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.

Ignite Your Focus. Ember is a tool for Radical Simplicity. In a world of digital noise and endless scrolling, Ember helps you reclaim your attention through a unique visual ritual. How It Works Unlike standard timers that just count down numbers, Ember uses "Visual Engines"—beautiful, animated themes that evolve and grow as you focus. Press to Ignite: Simply press and hold the screen for one second to start. This intentional act creates a moment of commitment to your focus session. Visual Anchor: Watch as a tree grows or a crystal forms. These Skia-powered visuals provide a calming anchor for your eyes, preventing the urge to check other apps. Zen Mode: The interface auto-hides after 3 seconds, leaving only the living visual to keep you tethered to the present. Key Features Living Visuals: Choose from engines like Growth, Crystal, Spiral, and Eclipse to match your mood. Track Your Journey: A clean calendar heatmap tracks your daily streaks and total focus hours. Earn Your Progress: Maintain a 30-day streak to unlock the exclusive "Orbit" engine. Flexible Flow: Set sessions from 1 minute to 12 hours (Premium) to suit everything from a quick breather to deep work. OLED Optimized: A minimalist, dark aesthetic designed to reduce eye strain and save battery. Why Ember? Ember is designed to fade away. There are no ads, no social feeds, and no gamified clutter. Whether you’re trying to stop doomscrolling, studying for an exam, or managing ADHD, Ember provides the calm environment you need to stay on track.
