The network is not always available. The Omamori mobile app is designed to keep working without a connection.
How it works
When you lose the connection, you can keep recording your sales and routine operations. The app stores them on the phone and shows a note that they will be synchronized later.
Synchronization
As soon as the connection returns, the app automatically sends the pending operations to your online workspace. Your phone data and your office data become identical again.
Tip: open the app for a moment once the connection is back, to let the synchronization finish.
Note: until operations are synchronized, they are only visible on the phone that recorded them.
