Hi, is there a way of staying logged in within the smart phone app for more than 24 hours?
In short, no.
As stated at
tokens obtained via email will last 24 hours for increased security.
Tokens obtained via Google or Apple last longer, but users can revoke them anytime on the Google or Apple side.
It is worth mentioning that authentication is only needed when communicating with the server, for example downloading a project or uploading entries. During the data collection, no exchange of credentials with the server is performed.
