Questions

How does it block apps? ▼
LearnScreen uses Apple's official Screen Time API (FamilyControls). When you open a blocked app, iOS shows a shield screen with your vocabulary flashcards. It works system-wide — even in the background.
Can I bypass the block? ▼
The block uses Apple's native Screen Time framework, so blocked apps can't be opened without reviewing flashcards first. After you complete a review session, the app unlocks for a calculated period (from 15 minutes up to a few hours, depending on your settings). It re-locks automatically when the unlock period expires.
What languages are supported? ▼
LearnScreen supports 11 languages: English, German, Spanish, French, Italian, Japanese, Korean, Polish, Portuguese (Brazilian), Russian, and Chinese. Each language has 1,080 curated words organized into 18 directories by topic. You can also add unlimited custom words in any language.
Is it really free? ▼
Yes! The free plan includes 5 review sessions per day, 5 words per session, and access to all word directories and custom words. LearnScreen Pro lets you review up to 50 times a day, customize words per session (3–20), skip sessions, and learn words 3x faster. Available as monthly, annual, or lifetime purchase.
Does it need internet? ▼
Daily use works offline — all 1,080+ words are bundled with the app, and shields fire on the lock screen without any network. Internet is needed only for restoring purchases and for the optional iCloud backup that syncs your progress to your own iCloud (not our servers). No account required.
Where is my data stored? ▼
On your device by default. If you’re signed into iCloud, your vocabulary progress backs up to your own iCloud (Apple, not us) so you can restore it after reinstalling or switching iPhones. We never see your words. We use anonymous usage analytics (no personal data, no email) to understand which features matter and fix bugs.
