Daily Plank
Time your plank, build a habit
Free · In‑App Purchases · Designed for iPad. Not verified for macOS.
Pick today's plank from 10 sec to 3 min and tap. After a 5-sec "Ready", the timer counts down. Days you train are logged, and your streak and best build up.
How many seconds will you plank today?
Plank Timer is a simple timer and log app that makes the classic core exercise easier to keep up. Pick a duration and tap the big center button. A 5-second "Ready..." lets you get into position, then the 1-second countdown begins. When you finish, it's logged automatically.
■ Simple to use
1. Pick a duration (10 sec to 3 min, in 10-sec steps)
2. Choose your target sets (1 to 10)
3. Tap the center button, "Ready" for 5 sec, then start
4. After each set, see "X / Y sets done, Z to go"
Because you can start short, even on a tired day, just 10 seconds is easy to keep going.
■ The more you keep it up, the more your record grows
- Streak: how many days in a row you've kept going
- Best time: keep updating your longest time
- Total count: total sets you've done
- Last 14 days dots: a calendar-style record
■ "Try going a little longer today"
The app suggests a duration just 10 seconds longer than last time. Tap "Use" and it's set. No need to push all at once.
■ Reminders (optional)
- A midday nudge if you haven't trained yet (12:30 by default, adjustable)
- After one session, a gentle "one more?" 3 hours later
You can turn notifications off; the timer and log still work.
■ Light / Dark
Switch between a bright and a dark navy background, or set "Auto" to follow your device.
■ Privacy and offline
All records are saved only on your device. No login, no account. Nothing is sent to a server.
