PushUp Time makes exercise a daily habit by tying it to something you already do dozens of times a day: picking up your phone. Choose the apps you open most. Before they open, you do a quick set. The camera counts your reps, and once you hit your number, they're yours for as long as you chose. Small sets add up to hundreds of reps a week, without ever planning a workout. FIVE WORKOUTS Push-ups, squats, lunges, jumping jacks and sit-ups. Mix them up to work your whole body. HANDS-FREE REP COUNTING Prop up your phone and move. PushUp Time watches your form and counts each full rep. No wearables, no equipment, no logging. TRAIN AT YOUR LEVEL Set how many reps each break costs: 15 minutes, 30 minutes, 1 hour, 2 hours, or a custom length. Start easy and raise the bar as you get stronger. TRACK YOUR PROGRESS See your reps by day, week and month, build a daily streak, and watch your totals climb for every exercise. BUILT TO KEEP YOU GOING • Choose which apps need a set before they open. • Set times of day when a workout is always required. • Give apps a daily allowance before reps are needed. • Lock in focus time when you want no breaks at all. WORKS OFFLINE Sets done without a connection still count and sync when you're back online. PRIVATE BY DESIGN Reps are counted on your phone. Your camera video is never uploaded. Available in English, Arabic, Chinese, French, German, Hindi, Italian, Japanese, Korean, Russian, Spanish and Turkish. SUBSCRIPTION PushUp Time requires a subscription to use. Payment is charged to your Apple ID at confirmation of purchase. Subscriptions renew automatically unless cancelled at least 24 hours before the end of the current period, and your account is charged for renewal within 24 hours before the period ends. You can manage or cancel your subscription in your App Store account settings. Any unused part of a free trial is forfeited when you buy a subscription.
