Charts are created and stored in the AstroGraph Cloud and then downloaded to Android devices so that they may be subsequently viewed even when you do not have cell service or internet access; i.e. network is unavailable.
If you access TimePassages Online
with your Android username and password, you will then be able to view and edit your charts created either on the website or in your device app. The charts are automatically synchronized at a current timing of every 5 minutes, which can be changed in the settings under "Sync Frequency for Cloud Charts and Settings."
If you are actively switching between the online browser view and the Android app, you may wish to speed up the synchronization frequency. You can perform a manual synchronization by going to settings under "Sync Frequency for Cloud Charts and Settings."
