RotStop

A completely free, secure, simple exersice based screen time limting app.

Functionality

Movement is the unlock.

RotStop sits on top of Apple's Screen Time framework. The apps you pick stop opening — until you've done something physical, waited something out, or until the schedule says they can again.

Walk to unlock

Set a step target for a blocked app. RotStop reads your live step count from CoreMotion — when you hit the target, the app opens. Stop walking, and the wall comes back the next day.

Fitness prerequisites

Require that a fitness goal be met before an app can open at all. Pulled from Apple Health, so any source counted by HealthKit — phone, watch, or third-party tracker — qualifies.

Timer challenges

Prefer to wait it out instead of moving? Set a cool-down timer the app must survive before opening. Hard Mode locks your unlock decision in for the rest of the day.

Schedules & limits

For the apps that don’t need a challenge — block them outright on a recurring schedule, or cap how long they can be open each day.

Pricing

Free. No ads. No catch.

RotStop was built as a personal tool and shared because others might want it too. There's no paid tier, no subscription, no “pro” unlock, and no ads. That's the whole pricing page.

No ads, anywhere.
No in-app purchases.
No subscriptions.
No upsells or paywalled features.

RotStop Privacy Policy

1. Data we collect

None. RotStop does not collect, store, or transmit any personal data. The app has no user accounts, no logins, no servers, no analytics, no crash reporting, and no advertising identifiers.

2. Data we share

None. There is no data to share because there is no data collected. We do not sell, rent, disclose, or otherwise transfer any information to third parties — there are no third parties involved.

3. Third-party SDKs

RotStop does not embed any third-party analytics, advertising, attribution, A/B-testing, or crash-reporting SDKs. There are no integrations with services such as Firebase, Google Analytics, Mixpanel, Amplitude, Sentry, AppsFlyer, or similar.

4. Permissions and how they are used

RotStop requests the following permissions. Each is used exclusively on your device and never transmitted off it:

Screen Time (Family Controls). Used to select which apps and categories to block and to enforce those blocks. Selected app identifiers are tokens generated locally by Apple's framework.
Health (read). Used to check whether you have met fitness prerequisites (for example, a daily step goal) required to unlock blocked apps.
Health (write). Used to record completed unlock challenges as workout entries in Apple Health, if you opt to grant write access.
Motion & Fitness. Used for live step tracking during a step-target unlock challenge.

5. Network access

RotStop makes zero network requests. The app does not contact any server we operate, any third-party service, or any analytics endpoint.

6. Children’s privacy

RotStop is appropriate for users of all ages. Because the app collects no personal data from anyone, it collects no personal data from children — including no data covered by the U.S. Children’s Online Privacy Protection Act (COPPA), the UK Age Appropriate Design Code, or comparable regulations.

7. Your rights under GDPR, CCPA, and similar laws

Because we do not collect or process any personal data, there is no data to access, correct, port, restrict, or delete. The configuration RotStop stores lives only on your device — uninstalling the app deletes it. You may withdraw permissions at any time in iOS Settings.

8. Data retention

Not applicable. No data is collected, so no data is retained. App configuration is held in local iOS storage and is removed when you delete the app.

9. Changes to this policy

If RotStop’s data practices ever change, this policy will be updated. Material changes will be highlighted in the release notes of the app update that introduces them.
