## What is Plank?

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.
