Challenge
Before
Almost no learning app dedicated to string players existed on the market, leaving solo practice without accompaniment. An authentic ensemble experience depended on in-person lessons.
Practicing alone with no accompaniment
No sense of ensemble
Scores, tutorials and accompaniment in separate services
Requires juggling 3–4 apps
No sync between lesson videos and scores
Switching screens breaks concentration
Score-sales model inefficient with per-item downloads
A payment flow on every purchase
Solution
After
Simultaneous iOS / Android development with Flutter; Firebase backend (Auth + Firestore + Storage + Messaging). Semi-automatic accompaniment via MusicXML parser + audioplayers; tutorial sync through YouTube player integration. IAP point-purchase model.
