I definitely pressed the spacebar every solve. I have no idea how to do that in cstimer.
fivetimer has a "drop to stop" feature. That's all I know.
I like FiveTimer for all my puzzle needs. Best timing app I've ever used on my phone. It has scrambles for all WCA puzzles (including Square-1). Easily worth a dollar.
