Your personal discovery roulette deck and offline library for everything you notice, wonder about, and want to remember.

Curio is a beautifully crafted Android app that combines two powerful ideas: discovery and collection. Imagine a deck of cards, each one prompting you to notice something new — a fleeting thought, an interesting pattern, a strange observation. You flip the card, explore the prompt, and decide to keep what resonates with you. Those "keeps" become part of your personal library — a private, offline collection of little curiosities that make life interesting.
Built with Kotlin and Jetpack Compose, Curio is designed to feel fast, responsive, and delightful to use. It's not just a tool; it's a companion for your natural curiosity.
Swipe through a randomized deck of prompts and ideas designed to spark your curiosity and help you see the world fresh.
Save your favorite discoveries and curate your own collection. Everything works entirely offline — your data never leaves your device.
No accounts. No tracking. No cloud servers. Your notes and what you notice are 100% private and stored securely on your phone.
A clean, modern interface with smooth animations and thoughtful typography, making note-taking feel premium and enjoyable.
Capture quick thoughts, long reflections, lists, or freeform text. Organize with tags and revisit your past discoveries with ease.
Native Kotlin and Compose mean blazing-fast performance with a small footprint. Runs great on any Android device.
Curio is primarily designed for Android, but you can run it on your Windows computer using an Android emulator. Here's a step-by-step guide that requires zero programming knowledge.
.apk — that's the Android app package. If you see multiple files, choose the one with the highest version number.
.apk file onto the emulator window. It will install automatically within a few seconds.
Don't worry about knowing what these terms mean — most modern computers and Android phones easily meet these requirements. If you have any doubts, try it anyway; Curio is very efficient and runs smoothly on modest hardware.
Open Curio once a day, pull a card from the roulette deck, and spend just two minutes noticing something in your surroundings — a color pattern, a sound, a design detail, an idea. Write it down, save it, and watch your collection grow. After a week, you'll be surprised at how much richer your daily life feels.
Use tags like #brainstorm, #inspiration, #peoplenotes, or #random to categorize what you save. Later, you can filter by tag to revisit specific kinds of discoveries whenever you need a spark.
Since everything is stored locally, you can take Curio anywhere — on a plane, in a remote cabin, or on a commute with spotty signal. Your library is always with you, always accessible, and always private.
Once a month, scroll through your entire library. You'll find forgotten ideas, laugh at old thoughts, and reconnect with your past self. This reflection can be surprisingly powerful and a great source of inspiration.
Curio is for the artist collecting glimpses of life, the writer looking for prompts, the student making unexpected connections, the busy professional slowing down to notice details, or the curious soul who simply enjoys collecting the odd and beautiful fragments of existence. If you appreciate your own thoughts and observations, Curio is for you.
Because it's built on offline-first architecture, no one else can see your notes — no ads, no data mining, no hidden servers. The app is yours, your data is yours, and your peace of mind is guaranteed.
Yes! Curio is 100% free and open-source. There are no in-app purchases, no subscriptions, and no premium tiers. You get the full experience forever.
