Frequently asked questions

Which devices are supported?

iPhone running iOS 17 or later. Both apps work in portrait and landscape. They are not iPad apps, though they will install on an iPad and run at iPhone size. There is no Mac, Apple Watch or Apple TV version.

Do the apps work offline?

Yes, completely. Neither app makes a network request at any point. Everything, including the whole Theory curriculum, is installed with the app.

Do I need an account?

No. There is nothing to sign up for and no way to sign in. Your progress lives on your device.

Is my progress backed up?

Theory stores your completed lessons, bookmarks and quiz answers locally on the device. It is not synced between devices, and deleting the app deletes it.

How do I reset my progress in Theory?

Open Settings from the top of the Learn tab, then choose "Reset all progress". You can also use "Show welcome screen again" to see the introduction a second time.

Does Practice keep playing when I lock the screen?

Yes. Practice uses background audio, so the drone and metronome keep sounding when you switch apps or lock the phone. It also mixes with other audio, so you can run it alongside a backing track.

Are alternate tunings or left-handed mode supported?

Not yet. Both apps currently assume a six string guitar in standard tuning, right handed. Both are on the list. If they matter to you, say so by email, because that is how I decide what to build next.

Is there a light mode?

No. Both apps are dark only. Practice is designed to be usable on a dim stage and in a dark room, and a light theme works against that.

Can I buy the apps together?

Each app is sold separately on the App Store, and a bundle is available that costs less than buying them individually. Purchases and refunds are handled entirely by Apple.

I found a bug, or something is missing.

Email support@plectrum.app. Tell me which app, which device and which version of iOS, and what you were doing when it happened. I read every message.
