Never Forget – The Smart Way to Retain What You Learn We put so much time and effort into learning new things, but without regular review, we forget most of it in just a few days. That means all that hard work goes to waste. Never Forget helps you retain newly learned information (NLI) that doesn’t quite fit in flashcards. Using Spaced Repetition, a powerful learning method, it reminds you when to review so you can actually remember what you study. How It Works 1. Add something you’ve learned that you don’t want to forget. 2. Never Forget automatically creates reminders based on the repetition schedule you select. 3. Get a notification when it’s time to review. 4. Mark it as repeated within 24 hours to stay on track. With Never Forget, You Can: • Organize NLIs with custom colors, emojis, categories and tags • Set reminders at your preferred time • Add links and notes for extra context • Track your progress and upcoming reviews • Stay motivated with daily review widgets Beat Procrastination with the 24-Hour Rule Timely review is key to remembering what you learn. If you don’t mark an NLI as repeated within 24 hours of receiving a notification, it’s marked as failed, and your progress stops. Snoozed info is forgotten info. Why You’ll Love Never Forget: • Minimalist & distraction-free – No unnecessary features, just what you need. • No sign-up required – Start using it right away. • Free forever for up to 5 NLIs – No ads, ever. • Dark mode – Because we love it too. • iCloud backup – Keep your NLIs safe and synced. Upgrade to Premium for Even More: • Add unlimited NLIs • Unlock all repetition schedules (Fast & Super-fast) • Create and save custom repetition schedules • Access all colors and emojis • Back up and restore your data Work smart. Don’t learn to forget. Got any questions or feedback? We’d love to hear from you!
