A frictionless capture pad for the ideas you would otherwise lose. If you have ever woken at 3 AM with a great idea and nothing to write it on, or watched a brilliant phrase evaporate while you opened a heavier app, Fast Idea Book is for you. It is a calm, on-device idea book built around one job — capture the thought before it fades — and one principle: never make you wait or sign in. Open the app and you are already typing. Quick notes save with a single keystroke. Brainstorm freely without folder rituals, then tag entries afterward when your brain wants structure. Voice memo capture for hands-free moments, brain-dump templates for foggy mornings, and a search that surfaces the half-remembered note in seconds. Home Screen and Lock Screen widgets keep the latest idea visible, and the interface ships in 39 languages with full accessibility. Built for writers, founders, students, designers and anyone whose best ideas arrive at the worst possible moment.
