What jAMSKOOL is

jAMSKOOL is a collection of six music-training apps for musicians and curious listeners who want to understand music and improve their playing or singing. Ear Trainer offers 12 listening and singing quizzes, microphone pitch scoring, three difficulty levels, study mode, and progress tracking. Sing Trainer provides random-note, scale, and arpeggio exercises, with real-time pitch feedback and voice-range calibration. Polarity pairs tonal meditation sessions on interval polarity, chord gravity, and scale fields with a chord builder, library, journal, and quizzes. Build is an ear-training game in which players identify chord tones across five timed rounds, with three difficulty levels and a global leaderboard. The kIDS app has seven quizzes, a pass-the-phone Party Mode, and a Random Notes mini-game, also with three difficulty levels. The apps are available on Android and iOS, with free options and paid unlocks. Ear Trainer says it collects no personal data, processes microphone audio on-device, and stores progress locally. kIDS says it has no accounts, ads, third-party SDKs, purchases, external links, social features, or data collection, and also processes microphone audio on-device.
