Ratings and reviews

Update: Verizon S22 Ultra. Android 13. One UI 5.0. January security update. September Google Play Update. Been using the Ultimate version of the app for about 5 years now. I loved it from the get-go. I would still love it now, if it didn't force close every single time I open it. Please fix this soon! The app didn't have that many ads on the free version, but I went ahead and donated an OPTIONAL 5-6 bucks back in 2018 to get rid of them. Well worth it. Thanks for all the hard work, devs!

Love the app & how user-friendly it is. All the different categories are very helpful. A suggestion for an additional category: Time zones! Edit: As of 1/4/23 the app will no longer open on my Pixel 7. It crashes immediately whenever I try to open it, even after restarting. Will bring the stars back up to 5 once this is resolved.

It's good to see the switch button bug getting fixed! However it's still weird because it disappears whenever i scroll down and appears when i scroll up. It doesn't seems like there's any point in making it disappear in the first place. A nice change would be to move the switch button between the 2 values but if i could type in both boxes that would be even better. Another thing, what if the values would stay on top of the area at all times? Nice design, tons of units and well optimized though
