Plank Timer
Read full descriptionHide 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. Choose weekly, yearly, or a one-time lifetime unlock that never renews.

Grasp builds your workout, then gets out of the way while you train. Tell it your goal, your experience, how many days a week you train, how long a session is, and what equipment you can actually reach. It puts a session together from that, you log each set as you do it, and it works out your next weights from what you actually lifted. It works offline. Everything lives on your phone. WHAT IT DOES • Builds each session around your goal, your schedule and your equipment • Suggests your next weights and reps from your own logged sets • Warm-up sets worked out from your working weight • Rest timer that rings between sets and counts down in the notification shade • Intervals: a timer for rope, sprints, planks and anything in rounds, with your own presets • A body map showing what you have worked and what is still fresh • Weekly set targets per muscle group • Saved equipment profiles for every place you train • Share your day as a card over a photo • Swap any exercise for another that trains the same movement • 600+ exercises, most of them animated, with step-by-step instructions • 15 languages WORKS OFFLINE There is no server deciding your workout. The part that plans your session and picks your weights runs on your phone. Basements, planes, gyms with no reception: same app. FREE, WITH NOTHING TO UNLOCK No adverts. No subscription. No paid tier. YOUR ACCOUNT An account is used for one thing: backing up your training so it survives a lost phone. Only the first sign-up needs internet. You can export everything at any time and delete your account from inside the app. We do not use advertising identifiers, analytics, or usage tracking. Grasp does not ask for your location, your contacts, or your microphone. The camera opens only when you tap to take a photo for a share card. BEFORE YOU START Grasp suggests training weights based on what you have logged. It is not medical advice. Talk to a doctor before starting a new training program, especially if you have an injury or a health condition. Stop if something hurts.

Verdict
The clearest difference is in-app purchases: Grasp at none against Plank Timer's 2. Grasp also leads on update cadence (weekly vs every 6 weeks). On price, ads, device support and iOS requirement there is nothing between them.
