Infinite big squeeze!
At first I liked this app. Very simple to use, free, and worked great the first time I used it. The second time, I thought the “big squeeze” was never going to end — it’s supposed to be 10 repetitions, but I think it was 20. The next time, I quit after 10, and it filled in random letters for my progress. Today I counted how many reps it wanted, and got to 40 before giving up. It’s positively evil for an exercise app to count reps wrong! I hope it gets fixed.
