PlainLock
Read full descriptionHide full description
PlainLock is a deliberately simple screen-time self-control tool. TWO WAYS TO SET A LIMIT • Schedule blocks: choose days and times, then the selected apps are blocked. • Daily limits: after the minutes you set are used, the apps stay blocked until tomorrow. • Shared group limits: put distracting apps in one group so switching apps cannot bypass the limit. • Group app limit: each group supports up to 50 apps, with a clear message when the limit is exceeded. • Cooling-off period: when you really need temporary access, wait 5 seconds, then unlock for the short duration you chose. LANGUAGES • Available in Traditional Chinese, English, Japanese, and Spanish. READ BEFORE YOU BUY • One purchase. No subscription. No in-app purchases. • Every rule stays on your device. The app makes no network requests and collects no app data. • This is a self-control tool, not a security tool. You can always remove restrictions by disabling its Screen Time permission in Settings. • Applying or clearing a block depends on iOS scheduling and can take one to two minutes. • Requires iOS 17.0 or later. Only iOS versions tested at release are supported; future compatibility and continuing updates are not guaranteed.

Marked helps you save the words worth remembering, and brings them back into your life through daily reminders and home screen widgets. Save quotes, highlights, and passages from the books and things you read. Instead of letting them disappear into screenshots, notes, or forgotten highlights, Marked gives them a place to come back to. REDISCOVER WHAT YOU’VE READ Your favorite quotes shouldn’t disappear after you save them. Marked resurfaces your saved highlights so you can revisit ideas, sentences, and passages you once found meaningful. SAVE QUOTES AS YOU READ Found something worth keeping? Capture quotes from physical books with your camera, or import highlights from your favorite e-readers and reading apps, including Kindle, Apple Books, Kobo, Readmoo, WeRead, and HyRead. DAILY QUOTE REMINDERS Receive a daily reminder with something you’ve saved before. A small moment to revisit an idea, remember a book, or rediscover a sentence you had almost forgotten. HOME SCREEN WIDGETS Keep your favorite highlights where you’ll actually see them. Add Marked widgets to your Home Screen and let saved quotes naturally reappear throughout your day. ADD YOUR OWN THOUGHTS Reading the same sentence months later can mean something completely different. Add notes and reflections to your saved highlights and keep track of what they mean to you over time. MADE FOR READERS WHO HIGHLIGHT EVERYTHING Marked is for anyone who saves passages from books, articles, essays, and other things they read, but rarely goes back to them. Instead of building another archive you never open, Marked helps the ideas you care about find their way back to you. Save what matters. Rediscover it later. Remember more of what you read.
