A practice diary app for music teachers: what to look for

Mikey Hurdle, 26 October 2026

If you're thinking of swapping the paper practice diary for an app, there are a few of them now, and they're built around quite different ideas of what a teacher needs. I make one of them, Mewstro, so read this knowing that. I've tried to write the list I'd want if I were choosing, and most of it applies whichever app you pick.

1. Who pays, and what students get

Some apps charge the teacher, some charge each student or family, and some do both. It matters more than the price, because asking parents to pay for another subscription is where a lot of studios stall. Find out what a student gets without paying anything, and whether that is enough for the app to be useful to you.

In Mewstro the teacher pays for the studio and every student they invite gets the whole app without paying. That was a deliberate choice, because I didn't want a teacher to have to sell an app to parents.

2. Does it record more than minutes?

A diary that only counts minutes tells you how long, not how. Look for one where students can say what they worked on and how it went, in a few taps. That's the part that changes the start of the next lesson. If students have to type a paragraph after every session, they won't.

3. Can you set specific work?

Check whether you can set an assignment like “bars 12 to 24, 15 minutes a day” for one student or several, and whether their practice counts towards it on its own. If you prepare students for graded exams, see whether it can hold a longer goal with a date, so a student can see the weeks between now and the exam.

4. What you see, and how quickly

Open the teacher side on a trial and ask yourself whether you could get what you need in the two minutes before a lesson. A busy page of charts is no use at 4.55pm. Some apps also send a weekly summary by email, which is often what teachers end up reading most.

5. Which devices your students have

Ask your students what they have before you choose. Some apps are iPhone and iPad only, some are on Android too, and some run in a browser. Mewstro is on iPhone and Apple Watch, and students without an iPhone can use the web version in any phone's browser.

6. Competition, and whether you can turn it off

Points and leaderboards suit some students and put others off entirely. Check whether a leaderboard is optional, for the studio and for each student. A student who practises for twenty minutes after a long school day shouldn't see themselves at the bottom of a table. Mewstro has a studio leaderboard, and each student chooses whether to appear on it.

7. Privacy, especially for children

You'll be asking families to trust the app with their children's practice. Read the privacy policy. Look for what the teacher can see, whether data is sold or used for advertising, and whether the app shows ads to children at all. If an app can't tell you plainly what you'll see as the teacher, that's a warning sign.

8. What happens to your data if the app closes

Small apps close. Tonara, which a lot of piano teachers relied on, shut down at the end of 2023, and teachers had about two months to move. Ask what you'd get if the app you choose went the same way. Mewstro's commitment is that every user on every plan would get a full CSV export before anything went offline. I wrote more about looking for a Tonara replacement if that's where you are.

9. Try it with real students

Demo accounts always look tidy. The only test that counts is whether your students use it in an ordinary week. Pick two or three students who'll give it a fair go, run it for a month, and see whether you're walking into lessons knowing more than you did.

What Mewstro looks like

Here's a minute of it: the teacher dashboard, then what a student does when they practise.

It's £14.99 a month for up to 25 students, or £24.99 for a bigger studio, both with a 30-day trial. The pricing page has the details. I'm one person building it, and Ellie's studio, where I learn, has used it since the spring. If you try it and it isn't right for your studio, I'd like to hear why.
