I'm leaving my home for 3 months and keep this app running at my home to keep any eye on my home while I'm away. Will this app support running for 3 months with mobile data enabled and charger connected always?
Yes, it should. Please make sure you enable "Start at boot" option inside power management. Also make sure you calculate and allocate sufficient space for 247timelapse, otherwise, the app will delete older photos to reclaim disc space. I would also recommend you to conduct a trial for about a week or so in the same condition to see if it runs normally or able to achieve what you expect it to do.
