About Music Theory Helper
Music Theory Helper is an educational app built around the fundamentals of music theory, published by johgru apps under the package name com.okramuf.musikteori. It is aimed at anyone who wants to work through theory material on a phone or tablet rather than on paper.
What the app is for As an entry in the education category, the app is structured for study rather than entertainment. The name makes its focus clear: helping you engage with music theory concepts, and the tool is put together as a single self-contained package you install once and keep on your device for reference whenever a question comes up.
Device and storage requirements The build requires Android 7.1+ or newer. If your phone already runs that version or a more recent release, you should be able to install it without any special setup. The download occupies 88.9 MB, so it is worth checking that you have that much space free before starting the installation, particularly on a device with limited internal storage.
Version and release information This listing covers version v5.2, which is dated 2025-08-15. Keeping an eye on the version number is useful if you are comparing an installed copy with the one offered here, or if you want to confirm that you are looking at the most recent build the developer has published.
Who it suits Because the app sits in the education category, it works best as a companion for learners who want theory material close at hand, whether they are revising between lessons or working through topics independently. The compact footprint means it can sit alongside your other study tools without demanding much from your device.
