About

Plato

Features
Read full description

Some thoughts aren't meant to last forever. Plato is a beautifully crafted notes app inspired by ancient Greek aesthetics. Write your thoughts on digital scrolls, set a timer, and watch them vanish โ€” like words dissolving into the aether. DISAPPEARING NOTES Every note you create has an expiration timer. Choose from 5 minutes, 1 hour, 24 hours, 3 days, or 7 days. When the timer hits zero, the note is gone forever. LIVE COUNTDOWN Watch the time tick down in real time. A progress bar on each note shifts from gold to bronze to flame red as it nears its end. You'll always know how much time remains. BURN ON DEMAND Can't wait for the timer? Tap the flame icon to destroy a note instantly. Once burned, it can never be recovered. CLASSICAL DESIGN Every detail is crafted with care โ€” serif typography, parchment textures, gold accents, and daily quotes from Plato himself. Your fleeting thoughts deserve a beautiful stage. COMPLETELY OFFLINE Plato works entirely on your device. No accounts. No cloud. No internet connection required. Your notes exist in your hands and nowhere else. FREE & OPEN SOURCE Plato is completely free with no ads and no in-app purchases. The entire source code is publicly available on GitHub for anyone to inspect, modify, and contribute to.

About

Dayfly

Read full description

Dayfly is for notes you only need for a little while. Notes quietly disappear after 24 hours by default. Parking spots, Wi-Fi passwords, locker numbers, today-only reminders โ€” jot it down and forget about it. Dayfly cleans up after itself. Attach photos and videos too. That whiteboard, a receipt, a photo you only took to ask an AI about โ€” capture it and share it straight from Dayfly. Dayfly-managed attachments are removed when an expired note is cleaned up. Photo-library originals and shared copies remain. Want to keep something? One star makes a note permanent. โ€ข No account, no sign-up โ€” open and write โ€ข Stored on your device, with no account or cloud sync โ€ข No ads, no tracking โ€ข Minimal design, dark by default Dayfly Pro (lifetime ยท one-time purchase): โ€ข Multiple photos + video attachments (free: one photo per note) โ€ข Per-note expiry โ€” from 1 hour to 7 days, or forever โ€ข Lock Screen widget with your latest note and time left โ€ข Action Button & Siri quick capture (Control Center capture is free) โ€ข Notes fade out as they near expiry โ€ข Extra themes Not a subscription.
