Parent-configured Screen Time

Screen time, earned one word at a time.

SpellTo gently blocks distracting apps until your child completes a quick spelling challenge — turning idle taps into a moment of learning. You stay in control; everything stays on the device.

How SpellTo works

đŸ›Ąī¸

1. You choose the apps

In the parent area, pick which apps to guard using Apple's Screen Time picker. Your selection never leaves the device.

🔤

2. Your child spells to unlock

When they open a guarded app, a friendly shield appears. A short spelling challenge unlocks it for the time you set.

âŗ

3. It re-locks automatically

Once the earned time is used up, the app locks again — so screen time always comes with a little learning.

Built for parents who want calm, not surveillance

📊

Weekly progress report

See words completed, accuracy, and streaks at a glance — a simple weekly summary, computed on-device.

đŸŽšī¸

Grade-level difficulty

Pick an age or grade level and the word bank adapts — from three-letter words to real challenges.

🔒

Private by design

App selections, settings, and stats stay in a secure on-device store. No child data is sent to our servers. No tracking.

âœī¸

Your own words

Add custom spelling words with a picture or emoji — perfect for this week's school list.

🍎

Apple Screen Time

Built directly on Apple's Family Controls. Reliable OS-level blocking, no profiles or workarounds.

Effortless return

After the challenge, one tap takes your child right back to where they were. No friction, no confusion.
