Hold today's target, beat yesterday's record. An 8-step plank program that climbs from 30 seconds to 2 minutes 30 — with a streak worth protecting.
PREMIUM — PURCHASE REQUIRED: All features described below are part of Pro and require a purchase: a weekly or yearly auto-renewing subscription, or a one-time lifetime purchase.
Time every plank hold and climb a program that actually climbs with you. PlankPro sets one clear target — starting at a 30-second hold — and moves it up a step only after your best hold beats it, all the way to 2 minutes 30.
Most plank apps hand you a fixed 30-day calendar and shame you when day 14 jumps too far. PlankPro works off your real personal record instead: the 8-step ladder adds about 15 seconds per step, waits until you clear it, and lets you repeat any step as long as you need. The timer itself is built for someone face-down on the floor — a huge countdown ring you can read from a metre away, a screen that stays awake for the whole hold, and second-accurate timing that survives a locked phone.
WHAT YOU GET
• Today's target waiting the moment you open the app — Step 3 of 8, 60 seconds, one lime START button
• A timer that flips to KEEP GOING when you pass your target, and a trophy screen the second you set a new personal record
• Put the phone down and look away: if the app is in the background, a notification tells you the instant your target is reached
• A day streak that understands training — turn on rest days and up to two days off keeps a 5-days-a-week schedule alive
• Your last 7 days on one bar chart, every session logged with date and duration, your PR badged in yellow
• Five presets from a 20-second starter to 3 × 30s sets with timed rest — plus a custom target anywhere from 10 seconds to 5 minutes
PERFECT FOR
• Beginners who cannot hold 30 seconds yet and want a target that grows only when they do
• Runners and lifters who finish every session with one honest plank
• Anyone who quit a fixed 30-day challenge because the schedule ignored their actual progress
• Streak-driven people who need one number to protect every day
WHY NOT JUST USE THE CLOCK APP?
A stopwatch does not know your target. It will not tell you when you have hit it while your face is ten centimetres from the floor, it will not log the hold, it will not remember that yesterday's best was 75 seconds, and it will happily record an hour if you forget it. PlankPro alerts you at the target, caps a forgotten timer instead of logging dead time, and turns every hold into a data point on your ladder.
PRIVATE BY DEFAULT
Every session stays on this device. No account, no analytics, no ads, and the app makes no network requests. There is also a one-tap way to erase all sessions.
PREMIUM (PURCHASE REQUIRED)
PlankPro is a paid app. Full access unlocks the complete 8-step progression, the guided plank timer with all presets, full session history with the weekly chart, and custom hold targets. Choose a weekly subscription, a yearly subscription, or a one-time lifetime purchase — subscriptions auto-renew and can be cancelled anytime in your Apple ID settings.
PlankPro is a general fitness timer, not medical advice. Talk to a doctor before starting a new exercise routine.
Drop to the floor, start the 20-second starter preset, and put the first rung of the ladder behind you today.
