Gym first. Scroll later. GYMTIME locks the apps you scroll the most until you check in at your gym. Screen Time limits have an Ignore button. GYMTIME doesn't. HOW IT WORKS 1. Pick the apps you scroll the most, like TikTok or Instagram. 2. Check in at your gym. Check-in only works when you're actually there. 3. Your apps open back up once you've shown up, at check-in or after your workout. Your choice. WHAT PEOPLE SAY "I used to be so caught up in my phone that I would just end up pushing off the gym to some other time or not even go. But now that I use this I literally feel so much more productive and actually use the gym membership I'm paying for lol." Carter.Mitchell27, App Store review "This single-handedly forced me to get in shape since the regular iPhone screen time is too easy to bypass." Sophia Krause, App Store review WHAT CHANGES • You go on the days you planned. • The membership you pay for finally gets used. • You go to the gym instead of doomscrolling. • You scroll after your workout, without the guilt. • Your streak shows you you're someone who shows up. WHY THIS WORKS WHEN SCREEN TIME LIMITS DIDN'T Screen Time limits only work if you don't tap Ignore, and when you're tired, you tap Ignore. Reminders are easy to swipe away. GYMTIME has no Ignore button, so your apps stay locked until you go to the gym. MADE FOR YOU IF YOU • Open TikTok "for a second" and lose hours • Tap Ignore on every Screen Time limit • Pay for a gym you rarely use • Want to stay consistent without counting on motivation Gym first. Scroll later. Try free for 7 days. Subscription required after. Location permission is used to verify gym check-ins. An active GYMTIME Pro subscription is required for blocking.

Verdict
The clearest difference is monetization model: Built With Science+ at free with in-app purchases against GYMTIME's subscription. Built With Science+ also leads on ratings volume (5.4K vs 9) and device support (3 vs 1). GYMTIME's advantage is review sentiment (100% vs 80%). On price, rating, update cadence and ads there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. Built With Science+ sells 4 in-app purchases, starting at $29.99 per month and GYMTIME sells 6 in-app purchases, starting at $1.99 per 7 days. Whichever you choose, the download price is not the number that matters.
GYMTIME holds the better App Store score, 5.0 against 4.8. That said, the two scores are not equally well evidenced: Built With Science+ has 5.4K ratings behind it against 9, so its average is the more settled of the two. Written reviews point the same way: 80% of Built With Science+'s written reviews are positive against 100% of GYMTIME's.
Built With Science+ ships an update fortnightly, GYMTIME every 3 weeks. The most recent releases landed on November 9, 2026 and November 5, 2026 respectively.
