Description by Bum Tae Yoon Written by the developer, not by AppBrain. Click to read.
UtimateScale is a music scale learning assistant.

Are you confused and tired of difficult terms and complex scale structures such as Mixolydian and Locrian? With UltimateScale, you can learn by looking at a composition in staff score, directly touching a synth keyboard key on the app, listening by ear, and moving freely in key. In addition, you can learn the scale efficiently through a quiz using the Leitner System, which is famous for learning by memorization. In addition, you can upload and share comments of various scales and your own learning know-how through the Internet Archive.

- Learn the scale by looking at the sheet music and listening to the sound.
- The built-in touch synth keyboard allows you to learn while directly pressing the keys.
- This app does not support only C key. You can transpose from C to B and see how it performs in different situations.
- You can adjust the speed and octave during playback, and you can set the playback instrument as you like.
- In the quiz menu, learn various scales by solving problems and using flashcards.
- For quiz questions, effective learning is possible using the famous Leitner system as a memorization method.
- You can share and download new scales that have not yet been discovered through the Internet Archive, scales with comments containing your own learning know-how, etc.

This app is also

- Support dark mode.
- Compatible with both iPad and iPhone devices.
- Press scales using a hardware MIDI keyboard connected via Bluetooth or USB.
- MIDI keyboard is also supported in quiz mode.
