TuneKit - Tuner·Metronome

Pluck a string. TuneKit's guitar tuner figures out which one it is and shows you exactly how far off you are.

Then switch tabs to a metronome that stays locked to the beat, and let the app quietly log every minute you practice.

TUNE FAST, TUNE RIGHT
• Automatic string detection — no tapping through menus mid-tune
• A smoothed needle that settles instead of jittering
• Hold a string within ±5 cents for half a second and it gets a ✓; tune them all and you'll see "all strings in tune"
• Tap any string to hear its reference tone and tune by ear
• Set A4 anywhere from 430 to 450 Hz, with an A4 tone button

Built for more than six strings:
• Guitar: Standard, Drop D, ½ step down, DADGAD, Open G, Drop C, 7-string
• Bass: 4 and 5 string
• Ukulele tuner: high G and low G
• Violin, viola, cello, mandolin, banjo (open G)
• Chromatic tuner mode for any note
• Custom tuning: 1–8 strings, nudge each one up or down by a semitone

A METRONOME YOU CAN TRUST
• 30–250 BPM, plus tap tempo
• Clicks are placed at exact audio sample positions, so it won't drift over a long session
• 1–12 beats per bar in x/4 or x/8 — play 7/8 as 2+2+3, 3+2+2 or 2+3+2, and 5/8, 6/8, 9/8, 12/8 and more
• Eighths, triplets or sixteenths, with an accent on beat one
• Beep, wood block or rim click, with volume control
• Tempo trainer: add N BPM every M bars until you hit your target tempo, then it holds
• Keeps playing while you switch tabs; stops when you leave the app

PRACTICE THAT ADDS UP
• Time is logged automatically while the metronome plays or the tuner hears you
• One minute makes it a practice day — build a daily streak
• Daily goal from 5 to 120 minutes with a progress ring
• Last-7-days chart, month calendar and total practice time
• Home-screen widget with your streak and goal progress
• A 7 PM reminder, only on days you haven't played yet
• Back up to a file and restore it on a new phone
• A help screen full of practice tips

PRIVATE AND OFFLINE
Pitch analysis happens on your device. Mic audio is never recorded, stored or sent, and everything works offline. No account. No subscription — every feature is usable without paying. Ads stay in a single banner at the very bottom, never over the needle, and no full-screen ad appears while the metronome is playing. Prefer none at all? A one-time "remove ads" purchase is there. Available in 15 languages, with dark mode.

WHO IT'S FOR
Beginners tuning their first guitar, bassists and ukulele players, string students, drummers and guitarists working on odd meters, and anyone trying to practice a little every day.

Grab your instrument, tune up, and start day one of your streak with TuneKit.
