I involuntarily open Instagram and start scrolling reels, sometimes many hours a day. I want to uninstall the app but I talk to multiple people on it. Is there any app that blocks the scroll on Instagram and not Direct Messages on it?

Hello, I am trying to download a video from my camcorder to my iPhone via hello cam app. It states download was successful but i dont see it anywhere on my device. I also tried my iPad which is low on space but i got the same message and cannot find it. Any advice would be appreciated. Thanks
