Questions, problems and requests all go to the same place: support@dailyscales.com. You'll get an answer from the person who made the app.
Which devices does it run on?
Any iPhone running iOS 17 or later, and any iPad running iPadOS 17 or later. There's no Mac version.
Does it need an internet connection?
No. Everything works offline: the engraving, the band, the drone, your practice history. The app makes no network requests at all, so nothing is sent anywhere, ever.
I bought it on my iPad. Can I use it on my iPhone too?
Yes. The purchase belongs to your Apple Account, so install it on any iPhone or iPad signed in to that account and it's yours there too, at no extra cost. Your settings and practice history stay on the device where you made them.
My instrument is missing a fingering, or has a wrong one.
Tell me. Every fingering model was audited against the published methods, and a report from a player is how they get better. Send the instrument, the note, and what you expected to see.
Can I use it with my students?
Please do. Build a routine, then send it to a student as a QR code they scan with the Camera, or export it as a PDF and print it. If they're preparing an ABRSM grade, the graded shelves are already in there.
