What is the difference between save settings and write settings in the app?

Write Settings

Writes configuration parameter settings to permanent storage on board the Mōvi. Settings that have been written will now be loaded upon the next power up. If setting are not written, the last written setting will be loaded at power up.

Save Settings

Retrieves the configuration parameter settings from the Mōvi, and stores them to the hard drive or SD card on the device. Useful for being able to reload known settings or share settings with other users.
