About this app

Build unbreakable strength with dead hangs, planks, and wall sits. Hold Strong combines precision timing with smart tracking and Apple Watch integration — zero equipment needed. "Isometric exercise training is the most effective mode for reducing both systolic and diastolic blood pressure." — British Journal of Sports Medicine, 2023 WHY ISOMETRIC TRAINING Static holds are among the most effective and underrated training methods in exercise science. They activate up to 95% of muscle fibres, reduce systolic blood pressure by an average of 8.2 mmHg, and build functional strength with zero joint impact. No gym, no weights, no special clothing. Five minutes a day is all it takes. 30-DAY CHALLENGE Pick any exercise, set your current best and a 30-day goal, and Hold Strong builds a progressive daily plan that ramps up gradually. Track your streak, hit each day's target, and earn your completion badge. The first 7 days are free — unlock the full 30 days with Premium. PRECISION TIMER A tension-arc progress ring at 60fps with tenth-of-a-second precision. Hit your target and the ring turns gold — Overtime Mode keeps you pushing beyond your goal. PROGRESS TRACKING Personal records logged automatically. Weekly charts reveal your strength gains over time. Personal bests are celebrated when you hit them. APPLE WATCH A full-featured companion app. Track holds from your wrist with haptic feedback and real-time coaching — no phone required mid-set. VOICE CONTROL Completely hands-free. Say "start", "stop", or "next exercise". Over 200 motivational messages tailored to each exercise keep you going through tough holds. MOTION DETECTION Keep your phone in your pocket. Hold Strong uses the accelerometer to detect the moment you drop from the bar, stand from a wall sit, or break your plank — and stops the timer automatically. FREE EXERCISES Dead Hang, Plank, and Wall Sit — the three most effective isometric exercises, free forever. PREMIUM EXERCISES Unlock unlimited custom exercises with Premium. SIRI SHORTCUTS & NFC AUTOMATION Add Hold Strong to the Shortcuts app and say "Hey Siri, start my plank." Automate with NFC tags — tap your mat to launch instantly. APPLE HEALTH Every workout syncs to Apple Health automatically. SIMPLE PRICING Free to use. Upgrade once — no subscription, no recurring charges. Unlock unlimited exercises, 30-day challenges, 4-week chart history, detailed statistics, and Siri Shortcuts and support development

Latest release

What’s New

Version 4.2 Jun 12, 2026

You can now reorder your exercises. Hold any card to open the manage view, tap Reorder, and drag them into the order you want. Hidden exercises move to the bottom. Custom exercises now show their name on the card, so they're easier to tell apart. Also fixed a bug where the countdown voice could start late on your first workout after opening the app, along with some smaller stability fixes.
