### 5/5 — Just discovering this

*2025-09-08*

My initial impressions: This is the most visually appealing, neat and tidy resource for practicing scales that I’ve found. I love the built in metronome, timer and playlist functions. I also want to point out that if a developer is still updating their app after six years it then they actually give a **** and it’s not just a cash grab like the majority of apps on the App Store. And that’s pretty cool. The price is great, too. I would like to see the option to prevent the screen from going to sleep, though. Also, the play/pause button gets switched around (performs the opposite function) when you exit and re-enter the metronome page. Thank you!
