NurseLock is an NCLEX-RN® study app for iPhone and iPad. Finish a short daily drill and the apps you chose to block open again until your next study day.
The practice question NurseLock opens with. Answer it here.
How NurseLock works
First, choose what waits.
Pick the apps or app categories to block in Apple's own Screen Time picker. Blocking is optional, so you can also study without it.
Then set your study day.
Choose your blocking days and when a new study day starts. The default start is 4:00 AM, your local time.
Next, do today's drill.
Up to 12 NCLEX-style questions a day by default: 10 for review and 2 new. Every answer shows its reasoning.
Last, your apps open.
Finish the drill and NurseLock asks Screen Time to lift the block until your next study day starts.

You stay in control.
NurseLock asks a lot of trust: it can keep apps closed. So it keeps the rules plain.
- Blocking is optional.
- Use the drills without Screen Time, or add blocking when you want it.
- Turning it off is always free.
- Help with blocking removes every restriction, with or without NurseLock Pro.
- No account.
- No sign-up, no NurseLock server and no cloud sync.
- Your study stays on your device.
- Answers, notes and review history live in a local database on the device.
- Your apps stay private.
- Screen Time gives NurseLock opaque tokens, so it can’t read which apps you picked or how you use them.
- No ads, no tracking.
- No advertising, no behavioural analytics and no crash reports. Apple and RevenueCat handle purchases.
Pay once, or weekly.
NurseLock is free to download, and the sample question is free. The daily drill and app blocking need NurseLock Pro. Turning blocking off never does.
NurseLock Pro Lifetime: US$24.99, paid once.
- Lifetime: every Pro feature, paid once.
- Or Weekly at US$4.99 a week, with 7 days free for eligible customers.
- Both give the same full access: the daily drill, the complete question set and Screen Time blocking.
- In Australia: A$39.99 once, or A$7.99 a week. The App Store shows your local price.
The Weekly subscription renews automatically at the price shown before purchase unless you cancel in your Apple account’s subscription settings before the trial or current period ends. Payment is charged to your Apple ID. Deleting the app does not cancel a subscription. The Lifetime purchase does not renew. See the terms.

Finish the day’s drill and NurseLock asks Screen Time to lift the block until your next study day starts. The default start is 4:00 AM, your local time, and you choose which days are blocking days.
Yes, at any time. Open Settings, then Help with blocking, to turn blocking off or remove every restriction. It works with or without NurseLock Pro.
No. You pick apps in Apple’s Screen Time picker, and Apple gives NurseLock opaque tokens it cannot read. NurseLock does not read your use of other apps. It only schedules and lifts its own restriction.
The daily drill and turning on blocking. NurseLock is free to download, and the sample question comes before the paywall.
Pro is a one-time Lifetime purchase (US$24.99) or a Weekly subscription (US$4.99 a week), shown in your App Store currency. Eligible customers can try Weekly free for 7 days.
No. There is no account, no NurseLock server and no cloud sync. Your study data stays on your device, and device backups can contain it.

No. NurseLock is study practice for the NCLEX-RN. The question set is educational material. It is not clinical guidance, not medical advice and not a guarantee of exam results.
iPhone and iPad, on iOS or iPadOS 26.5 or later.
Remove restrictions first in Settings, then Help with blocking, so the block does not linger. If NurseLock is already deleted and a block remains, check Screen Time access for NurseLock in iPhone Settings and restart the iPhone.
Cancel the Weekly subscription in your Apple account’s subscription settings. Deleting the app does not cancel it, and refunds are handled by Apple. Lifetime is a one-time purchase and never renews.
