The best apps that make you exercise to unlock your phone (2026)

An honest roundup from the person who builds one of them. Everything below is as of September 2026.

I make HonorFit, so I’m not a neutral reviewer, and you should read this with that in mind. I’ve tried to write the page I’d want if I were choosing. It lists the real apps in this small category, explains the one design decision that divides them, and says plainly where HonorFit is the wrong choice.

For each app, I only included what its own App Store or Google Play listing, or its official website, says. If I couldn’t confirm something, I left it out. I didn’t include prices, because they change often and differ by country. Check the store before you subscribe to anything. The sources are listed at the bottom of this page’s source code.

The one question that divides these apps

Every app here does the blocking the same way. On iPhone, they use Apple’s Screen Time. On Android, they cover the blocked app with a lock screen. The real difference is how they know you did the reps:

• Camera and pose detection. You prop the phone up, and it watches you and counts. It’s hard to cheat. In exchange, you need a spot to put the phone, enough light and room, and a camera pointed at you before every unlock.
• The honor system. You type in what you did. It’s quick, private, and works anywhere, but nothing checks you, so you can cheat.

Neither approach is wrong. If you know you’ll lie to yourself, a camera is worth the setup. If the setup is what will make you uninstall the app by Thursday, the honor system is better. As far as I could find, every other exercise blocker below uses the camera.

Exercise-to-unlock apps

Pushscroll: Exercise To Scroll

Pushscroll is made by Pushscroll GmbH and is on both iPhone and Android. Its store listings describe the deal as “one pushup = one minute of app time” and say it counts reps with pose detection (“Can’t cheat”). The exercise list is the broadest here: push-ups, squats, lunges, jumping jacks, diamond push-ups, squat holds and situps. You can also earn minutes from your daily steps, through Apple Health on iPhone and Health Connect on Android. There are guided workouts, streaks and community features too. It’s free to download with in-app purchases.

Good fit if you want camera-verified reps, lots of exercise variety, and extra motivation from streaks and a community.

PushUp Time: App Blocker

This is an iPhone app from KAMAN LABS LLC. The App Store listing says its on-device AI counts push-ups, squats and sit-ups, without an internet connection. The developer’s website says it uses the camera and that no frames are uploaded. When you finish a set, you choose an unlock window of 15, 30, 60 or 120 minutes, for either the app you opened or your whole blocked list. It’s free to download with in-app purchases.

Good fit if you’re on iPhone and prefer fixed unlock windows to a running balance. Be aware that there’s a separate Android app with almost the same name from a different developer, so check the developer name before you install.

PushUp: Screen Time & Fitness

This is an Android app from AscentTeam. According to its Google Play listing, it uses the camera as an AI rep counter for push-ups, squats and planks. It gives the example of 15 push-ups for 5 minutes. As well as apps, it can also block websites and short-video feeds such as Reels and Shorts. It includes schedules and a focus timer. I only checked its Google Play listing.

Good fit if you’re on Android and want to block websites and apps in the same tool.

Push Up Challenge: App Blocker

This is an Android app from Valid Fitness Group. It’s built around a 30-day push-up program, with an app blocker on top: one push-up earns one minute of scroll time, and reps are counted by an AI counter using the front camera. It also has a 60-second push-up test and tracks personal records.

Good fit if getting better at push-ups is the goal, and blocking apps is a nice extra.

HonorFit Blocker

This is mine. It’s on iPhone and Android, and it’s the honor-system option. You scroll a wheel to log pushups, situps, pull-ups or squats. Every rep adds time to one shared balance, which only counts down while a blocked app is on screen. There’s no camera, no motion tracking, no AI, no account and no analytics, and nothing is sent from your phone. The free version caps your balance at 20 minutes. Pro adds custom exercises and rep values, timed workouts, pause mode, a daily baseline and reset-at-midnight. It costs $3.00 a month or $19.99 once.

The trade-off: HonorFit takes your word for it, so you can cheat. If you know you would, pick one of the camera apps above. I don’t mind recommending them.

Side by side

If you want friction without the exercise

Some people don’t want to work out for their phone. They just want a pause before the app opens. These three are worth knowing about:

• one sec (riedel.wtf). When you open a distracting app, it makes you take a deep breath first, and then you choose whether to continue. On iPhone it works through a Shortcuts automation. It’s also on Android and as a desktop browser extension. It’s free for one app, and one sec pro covers more.
• Opal. A focus app built around focus sessions, recurring schedules, app limits and weekly reports, on iPhone and Android. It’s free with in-app purchases.
• ScreenZen. It adds a delay before a distracting app opens, and the wait can get longer each time you open it. It also has per-app limits and time-of-day rules, and lets you “earn your opens” by breathing, journaling or learning something. It’s on iPhone and Android. The App Store listing describes it as free, with optional tips.

If you mainly want to measure your usage or set a fixed bedtime, your phone’s built-in tools may be enough. I compared them honestly in HonorFit vs. Screen Time.

How I’d choose

• You want verified reps: Pushscroll or PushUp Time on iPhone. Pushscroll, PushUp: Screen Time & Fitness, or Push Up Challenge on Android.
• You want no camera and nothing to set up: HonorFit.
• You want to block websites too: check the website-blocking claims in each listing. HonorFit locks apps only.
• You don’t want to exercise at all: one sec, ScreenZen or Opal.

Whichever you pick, give it two weeks and adjust the exchange rate before you decide whether it works. The first version of the rules is almost never the right one.
