Does the app work offline and in airplane mode?
Yes. Logging medications, symptoms, measurements and check-ins all work without a connection, which matters on a flight or anywhere with poor signal. Entries are stored on the device and sync to your account the next time you are online, so nothing is lost in the meantime. Features that pull live data, such as syncing a connected device, resume once the connection returns.
