How it works
Three steps, every day.
You set the rules once. From then on, screen time stops being a negotiation.
Create tasks
Type a task and the minutes it's worth, or take a photo of the school planner and AI suggests the week's tasks.
Your child does it and proves it
They take a photo with the in-app camera (no gallery photos) or answer a quiz about what they studied.
Minutes unlock the apps
Approve with one tap, or let approval be automatic. When time runs out, apps lock again on their own.
Features
Everything you need. Nothing you don't.
School planner by photo
One photo of the timetable or planner and AI turns it into tasks. You review and edit before saving.
Real app blocking
Choose the apps or categories to block. Works with the app closed, even offline.
Approval your way
Approve every task, or go automatic and cancel later if needed. The photo arrives on your phone.
Simple rules
Daily limit, blocked periods (school, meals, bedtime) and a button to lock or unlock right now.
Motivation without pressure
Badges, levels and a monthly completion rate. No daily streaks that punish a bad day.
Requests from your child
They can ask for extra time or suggest a task: "Can I wash the car for 30 minutes?" You accept or decline.
For the whole family
Several guardians and several children on one subscription. Mum, dad, grandparents: each with their own name.
Always reachable
Emergency calls and the apps you choose (Phone, Messages, WhatsApp) are never blocked.
For kids
A lock screen that motivates, never punishes.
When an app is locked, your child sees why and what they can do to unlock it.
- Shows the reasonNo minutes left, bedtime, or required tasks still to do.
- Straight to the tasksWith the minutes each one is worth.
- Minutes that don't vanishThey add up for 30 days; the oldest are used first, with a warning before they expire.

Frequently asked questions
Does it work on iPhone and Android?
Yes. On iPhone it uses Apple's Screen Time; on Android it uses accessibility and usage-access permissions. Parents and children can use different systems.
What does my child's iPhone need?
Apple only allows blocking that a child can't switch off when their iPhone uses a Child Account in your Family Sharing group. The app guides you through it.
Does my child need an account or email?
No. You link their phone with a code or QR from your app. We never ask for an email, date of birth or surname.
Does blocking work offline?
Yes. Rules and unlocked time are stored on your child's phone. Actions taken offline are sent when the connection is back.
What if my child tries to get around it?
On an iPhone with a Child Account, they can't remove the permission. On Android, you get an alert if permissions are removed, the clock changes or the phone stops checking in for 24 hours.
Does the AI see photos of my children?
Only photos of study material and the school planner, to create quizzes and tasks. Photos of tasks like tidying a room never go through AI. All photos are deleted within 7 days.
How much does it cost?
14 days free, then from €5.99 a month or €44.99 a year for the whole family. Cancel during the free trial and you pay nothing.
Can I share it with my partner or the grandparents?
Yes. Invite other guardians with a link. Everyone sees the same and can approve tasks, at no extra cost.
Fewer arguments about screens. Starting now.
ScreenDuty is coming soon to the App Store and Google Play.
