# Practice Proof - Practice Log > A music practice log and timer that counts only the minutes it hears played.

"Yes!" Practice Proof settles it kindly.

Start a session and put the phone near the instrument. Practice Proof listens and counts only the minutes it actually hears an instrument or singing. Breaths, page turns and short rests count; a long break does not. At the end you see both numbers: the minutes heard, and the time spent.

MADE FOR PARENTS OF MUSIC STUDENTS
• A daily goal per player, set to whatever the teacher asked for
• A timeline of every session: when the playing happened and when it went quiet
• The teacher's assignments (pieces, scales, études) with a weekly target, and each session tagged with what was practised
• This week drawn as notes on a staff: a filled note for every day the goal was met
• A streak that keeps going as long as the goal is met each day, and stickers to earn along the way
• Several players on one phone: brothers, sisters and grown-ups too
• Add a session by hand for practice away from the phone. It is marked as added by hand, so the log stays honest
• Notes on each session: what was practised, what the teacher asked for
• A practice sheet for the teacher, as a PDF or a spreadsheet, for a week, four weeks or a year, with a line for a parent's signature
• Optional recording, per player: play a session back or share the recording with the teacher. Recordings stay on the phone and are removed after 30 days unless you keep them
• One reminder a day at a time you choose, skipped once everyone's goal is met
• A running session on the iPhone Lock Screen and Dynamic Island, and a Start practice button for Control Center (iOS 18). On Android, a Quick Settings tile and a notification while a session runs

NOTHING LEAVES THE PHONE
The sound is checked on the phone as it happens and thrown away. Nothing is recorded unless you turn recording on for a player, and recordings are saved on the phone only. No audio is ever sent anywhere, and there is no account to make.

One honest limit: music from a speaker sounds like practice too. Practice Proof hears that music is playing, not who is playing it.
