About this app

Focus on one thing. Keep it forever.

In a world full of noise, Retn is your sanctuary for the single most important thought. We believe that multitasking is a myth. To truly remember something—to make it part of you—you must focus on one thing at a time.

Retn is not a notepad. It is a ritual for your brain.

■ THE PHILOSOPHY
Your brain needs rhythm, not overload. Retn restricts you to a single active note. You cannot start the next one until you have fully absorbed the current one. This constraint is the most powerful experience we offer.

■ THE RITUAL OF IMPRINTING

1. Write (Focus)
Open the app. A clean, distraction-free canvas awaits. Type your quote, vocabulary, or goal. Pull down to lock it in.

2. Absorb (Imprint)
Close the app and live your life. Retn works in the background.
- Widgets: Your focus stays visible on your home screen, seeping into your subconscious.
- Notifications: Scientifically timed nudges arrive 3 times a day (Morning, Noon, Evening). Just read, acknowledge, and let it settle.

3. Complete (Release)
Once the text is etched into your memory, swipe right to destroy it. Feel the satisfaction as it shatters into particles and disappears.

4. Rest (Consolidate)
After completion, Retn gives your brain a 24-hour cool-down period. Use this time to let the memory settle. True learning happens during rest.

■ KEY FEATURES

- Hyper-Minimalist Design: Zero clutter. Just you and your text.
- Tactile Interactions: Pull-to-save, elastic scrolling, and haptic-rich swipe gestures for a physical feel.
- Smart Scheduling: Notifications are delivered at optimal intervals (08:30, 12:30, 20:00) based on retention science.
- Home Screen Widgets: Keep your focus comfortably in sight without opening the app.
- Archive (Premium): Unlock your history to revisit past imprints.

■ WHO IS THIS FOR?

- Language learners mastering one difficult word at a time.
- Thinkers internalizing a life-changing quote.
- Goal achievers focusing on a single daily priority.
- Anyone tired of complex, bloated productivity tools seeking an essential experience.

Don't just take notes. Imprint them.
Download Retn and start your first focus today.
