Drum metronome & rhythm trainer: automatic tempo changes, click track with gaps.
Read full description
Accel is a free metronome app that handles the tempo changes for you. Instead of nudging the tempo by hand every few minutes, set a start tempo, how long to hold each step and how much to add, and Accel raises the tempo automatically, always on a bar line, never mid-phrase. When you reach your target it can ramp back down again, so one run takes you up and back.
Built for players who take their rhythm practice seriously: a practice metronome with a native, sample-accurate click track that keeps running with the screen off, tap tempo that doubles as a BPM counter, a gap trainer that drops in silent bars to test your inner clock, and a clean dark interface with nothing in the way.
Tempo trainer: dynamic tempo ramp
• Hold each tempo for a number of bars or a length of time
• Increase by 1–50 BPM per step, from 20 to 400 BPM
• Stop at a target tempo, or keep climbing open-ended
• Ramp back down to the start in the same steps
• Preview of the whole plan before you press play (60 → 65 → 70 · 5 steps · ~0:48)
• Live progress in the dial: bars left, time left, next tempo
Gap trainer: silent bars for timing practice
• Gap click with beat dropouts: silences whole bars while the clock keeps counting, so you hear whether you held the tempo
• Fixed pattern: e.g. 2 bars click, 2 bars silent
• Random pattern: set the chance of silence and the longest run of silent bars
• Ladder pattern: the gap grows one bar at a time up to a ceiling
• "Coming up" strip shows the next six bars as click, gap or ?
• Five built-in presets from Warm-up to Ladder, plus your own saved presets
Precise metronome for every time signature
• Sample-accurate timing in the native audio engine, visuals in sync with the sound
• 20–400 BPM, fractional tempi supported
• Tap tempo: tap the pulse you want and the tempo follows, even while the click is running
• BPM counter: tap along to a song and read its tempo, a quick beat counter for any music
• Time signature 2/4, 3/4, 4/4, 5/4, 6/8, 7/8 or 12/8
• Subdivision practice: quarter notes, eighths, triplets, sixteenths
• Accent any pulse, including the offbeat; accents play a higher click
• Beat ring around the dial that lights up on every beat
• Five synthesized click sounds: Tone, Click, Wood, Mechanical and Blip
• Volume control and haptic feedback on every control
Background metronome, made for practice
• Keeps clicking in the background and with the screen off
• Media notification on the lock screen with play, pause and stop
• Headset media buttons supported
• Every setting is remembered between sessions
• Full TalkBack support
• No account, no ads, no tracking. Online only for the Pro purchase, crash reports and feedback you send
