Stop logging practice.
Start practicing.
Just play. Tempo Kit writes down the day, the minutes, the tempo you finally hit. So on the night you swear you're not getting any better, you can scroll back and watch yourself get better.
- Auto-logs metronome, timer & video sessions on its own
- Add tags, ratings, and notes when you want, or leave it hands-off
- A Today plan shows what to work on, checking off as you play, and a reminder of what you have been neglecting
- Heatmap, practice analysis, and weekly & monthly reviews
- Turn a week, month, or year into a share-ready recap card
- Your data stays yours. Export your practice history as PDF or JSON, and import your backup anytime.


Record a take.
Your biggest breakthrough is one playback away.
The metronome tells you where the beat is. A recording tells you how you actually sound. Press record while you practice; every take is named, tagged, and waiting in that day's journal page when you come back.
- One tap to record, right beside the metronome and video controls
- Name, tag, and search them; add a note to remember what to fix
- Each journal day holds its own takes: play them back inside the day
- Private by default, audio is saved on your device


Never set up twice.
Pick up where you left off.
One song, one preset: tempo, video, speed, pitch, loops, notes, saved together. Line them up in a set list, switch from any page, and tomorrow starts exactly where today ended.
- 3 presets free · unlimited with Pro + folders
- Set lists & drag-to-reorder
- Pinned practice notes per preset
- Export & import as a backup file

Slow it down.
Loop it. Nail it.
YouTube and Bilibili out of the box, or connect Spotify, Apple Music, almost any music tab. Slow the passage. Drop it into your key. Loop the two bars that keep escaping you, until they don't.
- Speed 0.1×–3×, pitch ±12 semitones
- 5-band EQ + vocal reduce or boost
- A–B loops and BPM & Key detection
- Press M to drop a marker on the passage you're drilling with a note, saved per video, and jump back to it later
- YouTube, Bilibili, your own files, or any tab you connect

Hold one note.
Train your ears against it.
A sustained reference drone for intonation, ear training, and long tones. Pick a note, stack intervals into a full chord, choose a timbre, and it keeps sounding while you use the tuner, metronome, or videos.
- Any root note and octave, with 12 stackable intervals (hear a full chord/scale)
- Six timbres from pure sine to harmonic-rich tanpura
- Keeps playing across tabs, with an auto-stop timer
- Save your favourite drone setups and recall them in one tap


Keep steady time.
Stay in tune.
A full metronome (30 to 600 BPM, tap tempo, subdivisions, swing) and a chromatic tuner that shows note, cents, and Hz in real time. Your mic audio never leaves your device.
- 30–600 BPM, subdivisions, tap tempo, swing feel, per-beat volume, 9 click sounds
- Precount, tempo ramp & polyrhythm layer
- Note, octave, cents & Hz · A4 reference 415–466 Hz
- Tuner mic audio processed locally, never recorded


Start the clock.
Showing up is the win.
Set a minute countdown to start, 10 minutes for the drill, let the stopwatch lap each take, or keep both on one screen. Then open the panel tomorrow and it says hello, and counts the day you showed up.
- Countdown timer with quick presets, and a lap stopwatch
- Show Timer, Stopwatch, or Both at once, and flip their directions
- A daily greeting welcomes you everytime you open the panel
- Counts every day you show up, never guilts a miss
- Optional practice reminders on the days and time you pick
- Six streak styles, and it all stays on your device
Less setup. More playing.
One side panel replaces your metronome, tuner, looper, drone, and practice notebook. Every tool inside, free and Pro.
Who it's for
One panel, different practice
The tools are the same. What you reach for depends entirely on what you're working on.
YouTube & Video Learner
Stop switching tabs while practicing
Watches song tutorials on YouTube while constantly pausing and switching tabs to a metronome or tuner. Tempo Kit puts speed control, pitch transpose, A–B loops, markers, tuner, and metronome right beside your video so you stay in flow.
Self-Reviewer & Recorder
Record takes & hear how you actually sound
Tired of guessing whether a passage is clean? Press record to capture a take on your device, listen back instantly with scrub controls, and keep recorded takes saved inside that day's journal.
Gigging Musicians & Performers
Setlists & one-tap preset recall
Rehearsing for a gig or stepping through a live setlist? Save your songs into ordered setlists with their exact BPM, count-in, tuning, and pinned performance notes. Switch from song to song in one tap without resetting your tools.
Data-Driven Student
Effortless proof of musical progress
Spreadsheets and paper logs feel like homework that gets abandoned by week two. Tempo Kit automatically logs your sessions, minutes, and tempos as you play, giving you heatmaps, tempo trends, and streak tracking without manual data entry.
Solo & Speed Driller
Break down the passages that fall apart
Isolate hard bars with A–B loops, drop playback speed down to 50% without altering pitch, and use Tempo Ramp to automatically step up BPM every few bars until the passage is effortless at full tempo.
Singers & Vocalists
Transpose key, reduce vocals & drone tune
Transpose backing tracks up or down ±12 semitones into your key, reduce lead vocals to hear yourself clearly over the mix, and use sustained reference drones to check your intonation on hard notes.
Great practice kit, everything I need is right here. I've been looking for something like this for a long time. The journal is fantastic, the auto-log and setlist is very cool.
as a musician honestly i gotta say this is one of the best metronome apps ive used, perfect for a browser
I just downloaded this and it works wonders with Youtube. It's one of the most useful extensions for my practice sessions, Thank You.
This is just so so so great and useful!!!!!!!! Helps me really stay focus
Woahhhhhh, this is lit. It helps me stay organized and get started faster, especially after a long day when I'm already tired and my brain is dead. I like how everything is in one place because I usually have trouble finding my tuner lolll, and it feels like work to keep switching and finding where those other tools are, when I just want to play and practice.
I love the mini timer, stopwatch, and notes feature. They're incredibly handy while practicing with a metronome. Great extension!
