Its original idea is actually interesting. Influencers always share perfectly composed scenes of their life, so it seems like they are always traveling, always doing something interesting. This app asks you at random times to please share what you are actually doing at that moment, it sends a notification when you should share, it has a window of some minutes to take a photo. You never know when the next bereal notification will show up. You can be sure, if someone always shares something interesting from their life constantly is not just faking it, it’s actually real.
I never used it, but some of my friends do, so this is based on their explanations.
While Shelly wifi devices can use their cloud, it’s optional. By default cloud is disabled, you can even make them report to your own MQTT server.
