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.
Tenoa

Tenoa is a local-first visual library. You save the things worth keeping: pages, images, videos, notes. They become plain files in a library you own, on your own devices. WHAT YOU DO WITH IT - Save from anywhere. Share to Tenoa from Safari, Instagram, or any app with a share sheet. - Browse it visually. Your library is a grid of the things you saved. - Find things again. Search across everything you have saved. - Open it anywhere. Your items are plain files. You can read them, back them up, and move them without Tenoa. NO ACCOUNT There is nothing to sign up for. You never give Tenoa an email address. Open the app and start saving. YOUR LIBRARY STAYS YOURS Tenoa has no accounts or tracking. It hosts no library, and items live on your devices. If you pair Tenoa on this device with the Tenoa desktop app, your library syncs between them peer to peer with end-to-end encryption; Tenoa-operated rendezvous servers only help your devices find each other and never see readable content. WORKS WITH YOUR COMPUTER The desktop app adds browser capture and runs AI summaries and tags on your computer. An optional cloud AI is off by default and uses only your own provider key. Searching by meaning also lives on the desktop. Pair once and everything you save on your phone appears on your desktop, and the other way around. The iPhone and iPad app also works on its own: save, browse, and search without any other device. WHAT IT COSTS This app is free. No subscription, no in-app purchases. A sample library is included so you can look around before you save anything of your own. Questions: hello@tenoa.app
