Forked nestry into nestry+
nestry worked, but it carried a hosted backend and auth for what is fundamentally a two-person, private dataset. That's a monthly bill and an account system for data that never needs to leave the couple.
nestry+ is the same app rebuilt on Core Data with NSPersistentCloudKitContainer. Partner sharing is a CKShare. There is no server, no login, no analytics SDK — the app costs nothing to keep alive, which means it never has to die.
This is becoming a rule for me: if a hobby app needs a server to exist, it needs a reason to need a server.
