User Reviews

This app worked beautifully on my iPhone 14, but now that I upgraded to iPhone 17, it has stopped working. The two bars where you choose n and k no longer display the numbers. I can hear the sound when I scroll down but no numbers appear

all you have to do is turn off dark mode

This was a great little app, but on the last update, the scroll inputs (from and choose input numbers) are now blank. The results still show but I have to blindly attempt to change the inputs until the output looks correct. It was 5 stars before before that (and it may work for you... but if you update the iOS, Apple purposely kills your battery life to get you to buy a newer phone).
