What is Mixtuby?
A free YouTube music player and mixer. Pick a mood or browse curated playlists, paste your own YouTube links, and enjoy continuous, gapless playback (with crossfade on desktop). On top of the music: karaoke with synced lyrics, A-B loop, and Vibe Mode — the original Mixtuby experience, with relaxing games and sleep tools. Not just music: anything that plays on YouTube works here — full movies, podcasts, DJ mixes. No account required.
Tap Mix. Play. Enjoy. to dive into Vibe Mode.
Quick Start
1
Add music
Search for songs directly, paste YouTube links, or scroll down and tap any curated album card. Preview tracks before adding — tap ▶ to listen, drag the seekbar to seek, then tap + to add to your playlist.
2
Play & customize each track
Press Play, then tap the settings icon on any track in your playlist to set its speed, A-B loop region, and volume. Tap Next to save and move to the next track.
3
Enjoy continuous playback
Tracks flow one into the next with no silence — gapless on phone and tablet, with a smooth crossfade on desktop. Your playlist, position, and settings auto-save right on this device — reopen Mixtuby and you land back on the exact playlist, track, and spot you were last listening to here.
Continue on another device
Start a song on your phone, finish it on your laptop. Sign in with the same account on both — cross-device resume is off for guests. Each device is remembered on its own, so the card always points you at the other one.
1
Play on one device
Listen as usual. While music is playing, Mixtuby quietly saves your current track, exact position, and whole queue every few seconds.
2
Open Mixtuby on the other device
A Continue card appears near the top of the home page: “Continue from 📱 iPhone — Pick up at 2:14” . Nothing changes until you tap it. The same card also offers a plain Continue where you left off when your last listen was on this device.
3
You decide — continue or dismiss
Two clear choices, never automatic — see below.
▶
Tap ▶ on the card to continue
Tap the ▶ button on the card and your full queue jumps over and continues from the exact second you left off on the other device.
×
Tap × to keep this device
Don't want it? Tap × and whatever is already on this device stays untouched — the card stays away for the rest of your visit.
Search & Preview
The fastest way to build a playlist — search, listen, and add without leaving the page.
▶
Preview a track
Tap ▶ on any search result to hear it instantly. The full track plays in the main player with a seekbar on the result row.
DRAG
Seek within preview
Drag the seekbar on the previewing track to jump to any point. A time bubble shows the exact position.
+
Add to playlist
Tap + to add the track to your playlist. Preview stops automatically. Switch between results freely — only the last tapped plays.
TIP
Quick playlist workflow
Search → ▶ preview → + add → search again → repeat. When done, tap Start Mix. Your previewed and added tracks are ready for continuous playback!
Find a Song by Lyrics
Forgot the title but remember a line — or just a few fuzzy words? Open the By Lyrics tab (the magnifier, next to Quick Start and Add Tracks) and let Mixtuby find it for you.
TYPE
Type or paste a line you remember
Type a chorus line, paste a whole refrain, or just a few half-remembered words — the box grows to fit. Exact wording, spelling and order don't matter; a close fragment is enough.
🔍
Tap Search
Nothing happens as you type — tap the search button when you're ready. Mixtuby checks its own catalog first, and only reaches out to find the song if it needs to.
💡
Not sure? Pick a “Did you mean?” suggestion
If your words are too fuzzy to match exactly, Mixtuby AI suggests up to 3 songs it thinks you mean (artist — title, with the real line). Tap the right one and it loads into your player.
▶
Tap a result to play
Found it? Tap the matching song and it loads straight into your player, ready to go.
Notes — I have an idea ✨
Jot down ideas and to-dos without ever stopping the music. Tap the little pencil button next to Your Mood in the hero — a panel slides in from the right on phones, or opens as a centered window on desktop. Two tabs inside: sticky-note Ideas and a Todo checklist.
💡
Ideas — pin sticky notes
Tap ＋ New idea to pin a note to the corkboard. Tap any note to edit it right on the post-it — type your text, pick one of 8 colors, or tap 🗑 to delete. Drag the ⠿ grip in a note's corner to reorder the board. The first two notes are examples that vanish for good once you write a real one.
☑
Todo — a notebook checklist
Write a task on a line — press Enter or tap away to add it. Tick the box to cross it out in red, tap ✕ to remove the line. The pencil button shows a cyan badge with how many tasks are still unchecked (up to 9+).
⏰
Reminders — a nudge for any task
Tap ⏰ on a to-do, pick a date and time, and Mixtuby sends a push notification with the task's text when it's due. It works even without an account — just allow notifications when your phone asks. The reminder rings only on the device where you set it; checking off, deleting, or clearing the task cancels it.
⚙
Text settings — size, color, bold
Tap ⚙ at the bottom of the panel to set your writing size (13–48px), pick one of 6 ink colors, or turn on Bold. These stay on this device only — they don't sync.
CLOSE
Four ways to close — music plays on
Tap ✕, tap the dark backdrop, press Esc, or swipe the panel to the right. The music never stops, and the whole panel is hidden while you're in Sleep Mode.
☁
Saved on device — sign in to sync
Your notes always save on this device. Sign in to your Mixtuby account and they sync automatically across all your devices — stored encrypted, never shared, and deleted for good if you delete your account. Limits: 100 ideas, 200 tasks, 2000 characters per note.
NOTE
Anyone with your unlocked phone can read them
Notes aren't PIN-protected — on this device they're visible to anyone using your unlocked phone or computer. Keep anything truly private out of them.

Speed — 0.25x to 2x (great for practice or podcasts)A-B Loop — set start/end points, loop count, and what happens after loop endsVolume — override the global volume for this track
Tap Next in the dialog to save and jump to the next track — perfect for setting up an entire playlist quickly.
Settings Panel
Open Settings (gear icon in navbar) to find these options:
Sleep Timer
Set a timer (15m to 120m) and music fades out automatically. A countdown badge appears in the player. Tap again to cancel.
Notifications & Reminders
Set gentle reminders to come back and play music, even when Mixtuby is closed. Off by default. See the Reminders section below for details.
Now Playing
Shows the track name as an in-app toast (and a browser notification) when a new song starts, even with Mixtuby in the background. Stays on your device — off by default.
Crossfade (desktop) & Gapless
On desktop, crossfade blends tracks together (1-30s). On iPhone and iPad, playback is gapless — each track goes straight into the next with no overlap. Turn crossfade off any time to force gapless everywhere.
Stars Theme, Video Quality, Audio Mode
Enable animated stars background, choose video quality (360p–1080p), or switch to Audio-only mode to save data.
Reminders
Gentle nudges to come back and play music — they arrive even when Mixtuby is closed, in your own local time. Open Settings → Notifications to set them up. No account needed.
1
Turn on a reminder
In Settings → Notifications, flip on the Daily Mix card. The first time, your browser asks to allow notifications — tap Allow. On iPhone you must install Mixtuby to your Home Screen first.
2
Pick the time
Choose when the reminder fires — it arrives at the exact minute you set (17:44 means 17:44), always in your local time, no matter where you travel. Change the time later and you get a fresh reminder the same day.
3
Pick how often
Set the frequency: Daily , Every 3 days , Weekly (pick one weekday), or Custom (tap any days of the week you like).
Tap a reminder and Mixtuby opens right where you left off — same playlist, track, and spot. Turn a reminder off anytime — the device is unsubscribed and stops receiving it.
Sleep Mode tools
Sleep Mode is a calm full-screen mode with relaxing games and tools that play over your music — Karaoke, Rubber Duck, Baby Sleep, Typo, Breathe, Pomodoro, Party, Shooter, Constellation, Dropbeat, and Gems. They are all free, no account needed.
🌙
Browse every tool
Open the Features page (/features) to see the full list of Sleep Mode tools, each with a short description.
TAP
Play now — jump straight in
Tap Play now on any tool and Mixtuby enters Sleep Mode with that tool already open over your music — no setup.
🔗
Share a tool
Tap ⏸ to open a tool's Paused · Settings, then Share this game / tool 🔗 . It opens your device's share sheet (or copies the link on desktop) — whoever opens the link lands straight in that tool over their music.
Karaoke — Sing Along
Time-synced lyrics that scroll line by line over whatever is playing. Open Sleep Mode (moon icon) and tap Karaoke — the current line highlights automatically and follows the song. Switch tracks and the lyrics follow. Works on any YouTube song that has lyrics on file; if none exist, karaoke just stays off for that track.
Learn more about Karaoke →
Screen Lock (Child Lock)
Locks the screen so a child or a nightstand phone can't change the track, skip, or exit by accident — the music keeps playing. Screen Lock works with a free account. Tap the 🔒 lock button in the top navbar to lock; it then turns red.
Set or change the PIN in the Player Settings panel (Screen Lock card). Your PIN is saved to your account and follows you across devices. Forgot it? On the keypad, tap "Forgot?" — this signs you out (stops the music); set a new PIN after signing back in.
Rubber Duck (DJ Quack)
Digital debugging companion from The Pragmatic Programmer . Enable in Settings → Rubber Duck. Tap the duck button to summon DJ Quack — 12 skins, animated affirmations, particle effects. Explain your problem to the duck and find the solution yourself.
Learn more about Rubber Duck →
Sleep & Relax
Science-based sleep aid. Enable in Settings → Baby Sleep Game. In Sleep Mode, tap Sleep → choose a playlist (Baby, Rain, 528Hz...) → set timer → Start. Ducks fall slowly, tap to catch with warm particle effects. Screen dims progressively. Based on Cognitive Shuffle, bilateral tapping, and progressive dimming.
Learn more about Sleep & Relax →
Breathe
Guided breathing to fall asleep or calm down. In Sleep Mode, tap the Breathe card, pick a technique, then Start breathing. An animated circle expands as you inhale and shrinks as you exhale, with the phase and a countdown shown inside.
🎯
Pick by how you feel
Each technique shows the benefit it's linked to: 4-7-8 to lower cortisol and ease into sleep, Box to reduce stress, Coherent to ease anxiety, Physiological Sigh to lower panic fast, Long Exhale to wind down gently, Wim Hof to boost energy, Alternate Nostril to sharpen focus. A relaxation aid, not medical care.
🌬️
7 science-backed techniques
Choose 4-7-8, Box, Coherent, Long Exhale (4-8), Wim Hof, Physiological Sigh, or Alternate Nostril. Tap the info button on a technique to read what it does and the research behind it.
🫧
Long Exhale (4-8) — the gentlest one
Breathe in through the nose for 4 seconds, then out for 8 through pursed lips — as if cooling a hot spoon — which is what keeps the out-breath slow and even. Six cycles, tagged “Wind down”. There are no breath holds at any point, so it is the easiest one to try first or to use lying in bed.
🔊
Sound cues — breathe with eyes closed
Tap the Sound button to hear a real breath play as you inhale and exhale, with a short bip marking the end of each phase. Holds stay silent. Now you can follow along without looking at the screen.
⚙️
Pause & quick settings
Tap the ⏸ button to pause the exercise, or the ⚙ button for quick settings — toggle the breath Sound, the background Music, and a Mini player so your song stays in reach.
Pomodoro — focus timer
A focus timer that runs over your music — free for everyone, no account needed . Turn it on in Settings → Pomodoro, then open Sleep Mode and tap the 🍅 Pomodoro card. The outer ring counts the round down, the inner one is the song playing underneath, and the next unchecked item from your to-do list rides along on screen.
25/5
Pick your rhythm
25/5 is the classic — 25 minutes of focus, 5 of break — and 50/10 is for longer blocks. Every fourth round earns a longer break (15 minutes; on 50/10 it is every third round and 20 minutes). Tap Custom and the − / + steppers let you set all four numbers yourself: focus, break, long break, and how many rounds earn one.
∞
Flow — no fixed round
Tap Flow and focus counts up instead of down — it runs until you tap ☕ Take a break . The break is then worked out from how long you actually went (a fifth of it, never under 5 or over 30 minutes). Use it for work that a 25-minute cut keeps interrupting.
⚙️
Auto-start & alerts
Auto-start next phase is on by default, so focus and breaks flow into each other. Untick it and the clock waits at 0:00 with a ▶ button until you are ready. Alert me when a phase ends adds a notification on top of the alarm sound — worth it when the tab sits in the background, where a browser can mute its audio. Your browser asks permission once; refuse it and the box simply unticks itself.
🔥
Streak & your last seven days
Every finished focus round counts. Tap ✓ Finish to end the session and see rounds today, your day streak, your all-time total, and a seven-day bar chart of the rounds you ran. All of it works signed out, kept on this device — sign in and the streak follows you to every device you focus from.
Party Light Show
Turn the screen into a full-screen light show synced to the vibe. In Sleep Mode, tap the Party card to launch 11 effects — including a strobing Blitz mode and a packed Insane mode. Set the intensity, and drop your own custom text in the center with size and color controls. Great as a second-screen visual at a party while your playlist plays.
Rhythm games — Typo & Shooter
Two quick arcade games that play over your music. Open Sleep Mode and tap a card to start — your best score is kept on the leaderboard.
⌨️
Typo — type the falling words
Type each word before it reaches the bottom. You're scored on speed and accuracy. When lyrics are available, the words can come from the song you're playing.
🎯
Shooter — tap on the beat
Targets fly in to the beat — tap to shoot them before they pass, and chain hits for combo multipliers. Any track becomes a playable level.
Constellation — trace the stars
A calm star-tracing game in Sleep Mode. Open Sleep Mode (moon icon) and tap Constellation , then pick how you want to play. Your rank and collection are kept on this device — no account needed.
HUNT
Hunt — find the hidden shape
You get a constellation's name and a tiny FIND THIS poster in the corner. The real stars hide among look-alike decoys — tap the right ones to trace the figure. More decoys appear as your collection grows.
SLEEP
Sleep — calm & no-fail
The next star gently breathes — just follow it. No timer, no misses, made for drifting off.
PUZZLE
Puzzle — memorize, then rebuild
Watch the lit shape for a moment, then rebuild it from memory once the stars go dark.
✦
Score, ranks & the 88 collection
The big number counts every star tap (e.g. “4/4”). Finish clean — exactly the star count in Hunt, no wrong pairs in Puzzle — to earn an XP bonus; a sloppy finish still reveals the constellation but skips the bonus. XP builds a named rank (Stargazer → Cosmographer), and each first-time finish banks toward “X / 88 discovered” with a one-time First light bonus.
At the reveal you see the constellation's name, a short fact, and its myth — the story behind the figure. It holds a little longer so you can read it; tap Skip to jump ahead. Tap any discovered constellation in your collection to re-read its story. Want a harder Hunt? Pause and turn off the Reference poster in Settings to hide the FIND THIS outline.
Dropbeat — blocks on the beat
A falling-blocks game where the pieces drop on the beat. Open Sleep Mode (moon icon) and tap Dropbeat , then pick a vibe to start. Move and rotate the pieces to clear full rows — your best score is kept on the leaderboard.
🎵
Pick a vibe — it sets music & tempo
Choose Ambient, Lo-Fi, Hip-Hop, Pop, Electro, or Rock. Your pick sets both the background playlist and how fast the blocks fall — Ambient is the calmest, Rock the fastest.
⚙️
Pause & quick settings
Tap ⏸ to pause, then the ⚙ button for quick settings — toggle the game Sound, the background Music, and a Mini player so your song stays in reach.
Gems — match three
A match-3 puzzle over your music. Open Sleep Mode (moon icon) and tap Gems . Swap two neighbouring gems to line up 3 or more of a colour — they pop, the board cascades, and chains build into combos. Match 4 clears a whole line; match 5 makes a colour-bomb.
TIMED
Timed — 60-second score attack
Score as high as you can in 60 seconds — your best run is kept on the leaderboard.
ENDLESS
Endless — play with no clock
Keep matching for as long as you like, no timer pushing you.
ZEN
Zen — calm & no pressure
A relaxed mode for winding down — just swap and watch the gems cascade.

Why don't I always see ads?
Ad display is controlled entirely by YouTube — based on the video owner's monetization settings, autoplay behavior, your region, and your YouTube account. Mixtuby does not block ads. They may appear at any time.
How do I listen with the screen locked?
Background playback depends on your device and browser, not just on Mixtuby. On iOS, embedded players pause when the screen locks — YouTube Premium does not change this for third-party sites. On desktop and many Android setups, if you're signed in to YouTube in the same browser, playback can continue in the background. Lock-screen and Bluetooth controls work whenever the browser allows it. For guaranteed screen-off listening, keep the screen on (Focus mode) or use the official YouTube app.
Control from your car, lock screen & Bluetooth
Mixtuby talks to your device's built-in media controls — so you can skip tracks without touching the screen. Perfect for driving, the gym, or pocket listening .
🚗
Car & Bluetooth buttons
Steering-wheel, infotainment, and earbud/headphone next/previous and play/pause buttons control Mixtuby directly.
🔒
Title & artwork on display
The lock screen and car display show the current track title and artwork, with skip and pause controls.
🎙️
"Hey Google, next track" / Siri
Use Google Assistant on Android or Siri Now Playing on iOS to skip tracks by voice. (This is your phone's assistant — Mixtuby has no built-in voice command.)
With the screen on and Mixtuby in the foreground, these controls work for everyone. The real hands-free case — screen off or phone in your pocket — depends on your device and browser, not on Mixtuby (see "How do I listen with the screen locked?" above).
Ask your browser's AI to play music
If your browser has a built-in AI assistant (like Gemini in newer Chrome), Mixtuby teaches it a few tricks. Just ask in plain words — “play some focus music” or “search Mixtuby for Adele” — and the assistant can do it for you, hands-free.
🔎
Search & browse, hands-free
Your assistant can search Mixtuby's catalog, list the curated playlists, or check what's trending — and read the results back to you, without you tapping anything.
▶
Start a playlist or a Vibe tool
Ask it to play a curated playlist or open a Vibe Mode tool (Karaoke, Breathe, Party…) and it opens Mixtuby right on what you asked for.
NOTE
No AI in your browser? Nothing changes
This only works if your own browser has a compatible AI assistant. On every other browser Mixtuby behaves exactly as before — nothing is added, removed, or sent anywhere. The assistant runs inside your browser; Mixtuby just lets it search our own catalog and open links for you.
