Kegelia

Kegelia is an iOS Kegel & pelvic floor exercise app. Most people don't struggle with doing kegel exercises - they struggle with doing them right. A glowing jellyfish sets the rhythm: as its bell rises, you lift and squeeze; as it opens, you release. A gentle haptic taps on the squeeze, so you feel the correct "up and in" motion instead of bearing down.

Two things set it apart from the usual clinical timers. It's beautiful - one calm underwater world instead of the same blue-and-white stopwatch - and it's completely discreet: in stealth mode there are no labels or timers on screen, just the jellyfish, so to anyone nearby you're watching an aquarium.
