Description by Goo wong Kwon (from the App Store)

Ever had a great idea, written it down, and never found it again?

Notes apps just pile up. All-in-one tools get overwhelming. Lucid sits in between.

■ Catch the 3 seconds it lives
Tap the home screen widget and start typing. Don't pick a type or a place — just get it down.

■ Organize in 5 minutes a day
Swipe through your thoughts and answer one thing: "Where does this go?" No jargon — Projects, Areas, Resources, Archive.

■ Today, only what matters
Open the app and today's tasks come first. Each one done is a small win.

■ Your second brain, in your hand
No account, no login. Every thought stays safe on your iPhone.

Stop losing your best ideas. Let Lucid remember them for you.
