Changing my review again. This app is a good app, and it works for most people. If you have a Motorola Razr Flip phone like me, you might run into bugs with this app. Some people do and some don't, I would suggest paying for a week first to see if you run into issues before fully buying. It's definitely worth it. The devs do work to try and help everyone. There is another app by the same dev that does the same thing but covers Motorola, so far no issues there. Please support the dev!

I've been using the paid version on my z flip 6 for 2 years. There were some buggy periods, but lately it's been exactly what I want, and I think the paid subscription is worth it. My cover screen is a lot more usable since I can access any app without manually adding it, and I can add any widget (not just Samsung approved ones)

I really wanted to make this app work for a GIF for my Motorola Razr work but after countless tries and looking up tutorials it just doesn't work. Which really sucked because they make us pay for this, so now I just feel scammed.

Was planning to buy the premium for the external screen GIF and whenever I have clicked it, the app closes, restarted my phone and redownloaded the app multiple times and still crashes every time.
