Medician is a cross-platform mobile app for tracking PROs (Patient Reported Outcomes). Users are able to track their symptoms, get notifications for medications, exercises, and appointments.
Right now SQLite limits the scope of the project. Realm or WatermelonDB would be more suitable for advanced features, e.g. group by cause instead of symptom. Currently both DBs are not officially supported by Expo (see here and here) however custom development client could be a solution. We could either look into this, or wait for SDK 43 (arriving Sep or early Oct) which should have better/complete support for these modules.
