Evil Trainer Timer: Trick Yourself (or your clients) into longer planks
I’ve long suspected and frequently accused my personal trainer of having a fake timer app with imperceptibly longer seconds to trick me into planking longer. As it turns out, she was not using a fake timer app. We couldn’t actually find such a thing (probably because it wouldn’t exist in the App Store), so I threw one together. Evil Trainer Timer is an open-source SwiftUI clone of the iOS timer with a mode that extends each second imperceptibly such that “60 seconds” of planking takes 70 seconds.
