This is strange. There are 100s of scales. Each one at about 10 different positions and at all keys. 1000s of combinations. From the most basic Pentatonic scale to the more unknown Ukranian Dorian scale. Don't understand your comment. Please get in touch with the developers at LearnToMasterLtd@gmail.com so we can resolve.
Terrible
If you can get past the clunky, amateurish interface, I expect it is possible to use it to learn guitar scales, but it's not worth paying for.
Response from developer
Sorry you feel this way. The design is taken from all best practices like Nielsen principles and Material Design, so you can intuitively use the app to learn scales. Email the developers at LearnToMasterLtd@gmail.com to discuss.
Doesn't do what it says
