This Plank Challenge timer is designed to simplify multi-day fitness goals by automatically calculating incremental daily targets, and automatically setting the timer accordingly for each day of your challenge.
Choose easy, medium, or hard difficulty, or live by your own rules and set up a custom challenge!
This app was built specifically with a 30-day Plank Challenge in mind, but can easily be used for any multi-day time-based fitness program.
The app also helps you remember to plank every day, by sending you a gentle reminder a day after your last plank.
If you ignore it, it will only remind you twice more after that (after another day, and after a week). This app won't judge you, and it won't keep nagging you.
