Plank 30 Day Challenge - Core

Finally finish a 30-day plank challenge. Plank 30 builds a short daily core plan from one choice — your level — and keeps you coming back with a calendar streak, a home-screen widget and a daily reminder. All you need is a mat. ■ How it works • Pick Beginner, Intermediate or Advanced — beginners start with 20-second holds • Once a day: 3–6 moves — forearm, side, high, reverse and shoulder-tap planks • Finish and your 30-day calendar gets a check; your streak grows • Completed all 30? Move up a level, or run the same one again ■ Fixed what bugs people in other plank apps • No ads during your workout — not before it, not between sets • Remove ads once and every ad is gone. For real. • A 5-second countdown to get into position before each session • A gentle curve — no sudden jumps on day 14 or after rest days • Rough day? "Go easy today" makes holds 20% shorter • Missed a day? The plan waits for you instead of skipping ahead • Beeps for the last 3 seconds and every switch; the screen stays on ■ Keep it going every day • Home-screen widget: today's day, total time and streak • Daily reminder at the time you choose (default 7 PM) — skipped once you're done • Every 6th day is a rest day — just check in to keep your streak ■ No account, no subscription • Everything stays on your phone. No sign-up, no servers. • Free with light ads. Prefer none? A one-time purchase in Settings removes them for good. Stop if anything hurts.
