That's the most straightforward solution. I'm working on an Android app that syncs calls and texts to a Rails back-end and I try to keep the sync workflow as simple as possible. As for sync'ing, I found the following to be a huge boon for users:

- Allow the user to set sync to happen only when connected via Wi-Fi (not sure if this is possible in iOS, but it's easy to check how an Android device is connected to the Internet).

- Give options for sync intervals. Most of our users choose once a day. Other options include sync'ing a call or text right after it's finished or received if they need their data to be up-to-date within minutes.
