## What is One Plank?

A simple plank timer for building a daily core habit.

Tap Start, then just listen. Sounds and short voice cues guide you, so you don't have to watch the screen.

Made to keep you going
- Tell us how it felt: Hard, Just right or Easy. When it keeps feeling easy, we suggest adding 5 seconds
- Keep going past your goal and try for a personal best
- Tough day? Do just 10 seconds to keep your streak (up to twice a week)
- Celebrate milestones and unlock new app icons, like a gold crown at 30 days

Features
- Goal from 10 to 300 seconds, in 5-second steps
- Form tips during your plank, read aloud
- Streak, personal best and a 4-week history
- Widgets, Lock Screen widgets and a Control Center button
- Save planks to Health as core training (optional)
- Start with Siri, Shortcuts or the Action button
- Daily reminder at the time you choose

No account needed. Your records stay on your iPhone. No ads during your plank.
