This will be useful for programmers and nothing more. It would be better to do something useful for all people. For example, the most important thing is how to find a lost iphone, I recently read https://moonlock.com/how-to-find-lost-iphone about this. Of course there is already an app for this. But it can be improved. There are a lot of gaps in the current one, scammers and thieves have already learned to circumvent these problems. If you lose your phone, you are unlikely to find it.
