Plank Timer

Read full description

A plank timer that calls out every second for you. Set the hold, put the phone down, and let the voice, the 3-2-1 beeps and the haptic buzz tell you exactly when to brace, when you're halfway, and when you're done. Most people quit the plank early because they keep peeking at a stopwatch. This app takes the screen out of the equation: a full-screen countdown ring, spoken "Hold" and "Rest" cues, a halfway alert to keep your core tight, and a get-set countdown before every set. Then it logs the hold, grows your streak, and pushes the next target a little higher. WHAT YOU GET - Hold longer without watching the clock: voice cues, countdown beeps and haptics carry you through every second - Never wonder what comes next: multi-set core routines that chain forearm, high, side and reverse planks with timed rest between holds - A month-long plan that actually ramps: the 30-Day Plank Challenge takes you from a 20-second hold to a 5-minute hold, rest days included - Proof you are getting stronger: streak, longest hold, total core minutes, weekly total and a 7 / 14 / 30-day chart of core seconds per day - A level that climbs with you, from Core Rookie to Plank Master, so 40 honest seconds today still counts - Form you can trust: plain-English guides on plank technique, the four variations, the mistakes that kill results, and how to train safely PERFECT FOR - Beginners who can barely hold 20 seconds and want a plan, not a stopwatch - Anyone chasing a personal best on the forearm plank - Desk workers building core strength for posture and a happier lower back - Home and travel training with zero equipment and zero setup WHY NOT JUST USE THE STOPWATCH APP? A stopwatch makes you stare at your phone in the exact position where lifting your head wrecks your form. This one speaks. It counts you in, warns you at the halfway mark, beeps the last three seconds, buzzes when a set flips to rest, keeps the screen awake, and then writes the hold into your history so tomorrow's target is based on something real. A stopwatch forgets you the second you stop it. PRIVACY Every hold, streak and setting stays on your iPhone. No account, no sign-up, no ads, no tracking, no cloud upload. The whole app works offline, on a plane or in a basement gym. FULL ACCESS The full app opens with a membership: all four plank variations, all four multi-set routines, the 30-Day Plank Challenge and the 14-Day Core Reset, the custom-duration timer, your full history, and the charts and trends in Progress.
