Music Practice Apps: Why Tracking Time Isn't Enough

Before downloading another practice app, decide what you're actually trying to measure. Time and tempo are different metrics, and most apps are built to track one, not both.

What time-tracking apps measure

Minutes practised, streaks, reminders. Good for building the habit of picking up the instrument. Bad at telling you whether today's session made you better than last week's — a timer can't distinguish focused work from repetition on autopilot.

What speed-tracking apps measure

Clean max BPM on a specific passage, logged over time. Good for anyone whose goal is measurable technical progress — getting a lick, run, or fill from unplayable to fast. Bad at capturing anything that isn't tempo-driven, like tone, phrasing, or sight-reading.

Which one fits your practice

• Teacher-assigned repertoire, general skill-building, casual playing — a time-tracking or habit app is enough; consistency is the whole game.
• Technique-focused practice — licks, runs, rudiments, passages with a target tempo — you need BPM data, or you're guessing whether you're actually improving.

Most players are a mix of both, which is why the honest answer is often "use two tools, or one that does both."

A quick gut check

Ask yourself one question before you download anything: "If I open this app in a month, will it tell me whether I got faster, or just how often I showed up?" If the honest answer is "just attendance," you've found a habit app, not a progress tool — and that's fine, as long as you know which one you're holding.

A short checklist

Whatever you pick, it should manage these without friction:

• Log a number in under 10 seconds, mid-practice
• Separate fragments — don't force one tempo per whole piece
• Show a chart, not just a list of numbers
• Work offline, since practice rooms rarely have signal
• Not require the app to "hear" what you're playing — you tell it the number, it does the tracking

Crank. is built for the second half of that list — BPM per fragment, charted progress, offline by default — with a built-in metronome so you're not switching apps mid-session. Free on the App Store for iPhone.
