1SecPlank
+1 second of plank per day
Free · Designed for iPhone. Not verified for macOS.
1SecPlank is the simplest challenge in the world: every day, hold your plank 1 second longer than yesterday.
The app measures your max, then increases your goal by just one second each day. That's it.
HOW IT WORKS
• Start the timer and hold your plank
• Each successful day = +1 second tomorrow
• Build a streak and never let go
FEATURES
• Timer with visual and audio countdown
• Daily streak with streak freeze
• Detailed progress and statistics
• Levels to unlock
• Customizable daily reminder
WHY IT WORKS
The secret is minimal progression. 1 second seems like nothing — and that's exactly why it works. No excuses, no burnout.

- Apple Health: save each plank to the Health app, from your iPhone or your Apple Watch (turn on “Save to Apple Health” in Settings).
- Apple Watch: redesigned screens, sounds, and the app is now available in English and French.
- Fix: the watch now shows today’s target as soon as it opens, instead of staying on “Open 1SecPlank on your iPhone”.
