When ever and what ever inpired and always good done, even to think about it, having simply the Sangha of the Buddha in mind.
Good maybe collecting ideas and then coordinate it with Monastery master Moritz, maybe in 10 days, two weeks, he may have much more time.
Good to consider that monks, if keeping Vinaya, aren't that free to organice things and ones own labor, time, intention... may end, leaving things to carry behind.
Nevertheless it's all great practice on field and my person would always encourage to such, having the right perception of target for sacrifices in mind, the Tripple Gems, Nibbana.
Once Nyom get's more familar with all here (Dhamma), intent and conduct (especially), there isn't any problem to get any access.
In regard of app generally, Atma guesses that the main point of "need" is a matter of notification, maybe also login, since off-line as a whole isn't that interesting for a "social app".
