Hi!
Stolbitsa is an ear training app that can use real music for exercises, not just randomly picked notes like all other similar applications. This is a GitHub OAuth app and every ear training lesson is a public GitHub repository. You can create your own lessons and publish them on Github to share with other players.
All lessons are divided into 12 difficulty levels equal to the amount of notes in chromatic scale. You start learning from level 1 and gradually increase difficulty until you become an expert.
If you pass a lesson correctly you are rewarded with silver notes. If you guess 90% of notes you get 1 silver note, 95% - 2, 100% - 3. Later you can use the earned silver notes to give them to the lessons you like. The more silver notes a lesson gets the higher it is displayed on the main page listing. You can also star a lesson on Github and leave a comment. These are social network features of the app that all other similar apps are lacking as well.
This is intended to be some kind of a social network of people interested in music education on top of Github. You create and publish your lessons and get comments and stars for them. Every user has a public profile where their achievements and lessons they created are listed.
Currently only several initial lessons are created for each difficulty level. But nevertheless the app can already be used as a fully functional ear trainer. New lessons are constantly being added and I hope that more will be created by users.
You can play directly in the browser or as PWA on any platform, also Android apk is available for download. Playing is better on mobile, editing - on desktop. To create a new lesson click the edit icon in any existing lesson, then edit it and publish it as yours. I think the editor is self-explanatory. After you have created a lesson it is not shown on the main page until you give it at least one silver note, you can only view it on your profile page.
Please tell what you think about it, play it and try to create your own lessons!
