One plank a day. Start the timer, hold as long as you can, and watch the streak grow. A simple daily habit tracker for your core — no account, no clutter.
One plank. Every day. That's the whole app.
Plank is a focused daily habit tracker built around a single move: the plank hold. Start the timer, hold as long as you can, and log it. Come back tomorrow. Watch the streak grow.
A TIMER THAT GETS OUT OF THE WAY
• Big, clear time display
• Tap to start, tap when you're done
• Live progress against your daily goal
• A daily reminder so you don't forget
STREAKS THAT KEEP YOU HONEST
• Day streak front and center
• Yesterday's best time at a glance
• Goal-met state that makes today feel finished
• A 21-day strip on the home screen to show momentum
HISTORY THAT SHOWS THE WORK
• GitHub-style heatmap — every day you held, colored in
• Stat cards: total time, best hold, active days, average
• Tap any day to see every session from that day
• Recent list of your last few holds
HOME SCREEN WIDGET
Add the Plank widget to your home screen and see today's progress, your streak, and the
week so far — without opening the app.
PRIVATE BY DEFAULT
• No account
• No sign-in
• No analytics, no third-party tracking
• All data stays on your device
Built for people who want one thing tracked well, not ten things tracked badly.
