Casa do Zéps mascot markTHE HOUSE
OF APPS
A small independent studio
with room for big ideas.
A little about us

Built with curiosity.
Made for people.

Casa do Zéps is an independent app studio creating and maintaining digital products for different parts of everyday life. The collection ranges from personal tracking and movement to interactive storytelling and casual games.

Each app starts with a simple question: can software make this moment a little easier, more interesting, or more enjoyable? The answer looks different for every project, so each app gets its own personality and purpose.

Casa do Zéps is an ongoing, hands-on project: ideas are tested, details are refined, and existing apps continue to evolve after launch.

Say hello
How we think

Useful beats complicated.

Good apps don't need to do everything. They should make their purpose clear and help people get on with their day.

Start with a real need

Each app has a distinct job, whether that's recording a personal pattern, taking a small movement break, following a story, or playing a quick game.

Keep the experience clear

We aim for approachable interfaces, understandable choices, and features that serve the app's main purpose instead of adding complexity for its own sake.

Keep learning and improving

Apps are living products. Feedback, testing, maintenance, and thoughtful updates are part of making them useful over time.

Who makes Casa do Zéps apps?

Casa do Zéps is an independent app studio led by its developer, Gilson Nascimento. Apps are designed and maintained as separate products, each with its own purpose and support information.

Where can I download the apps?

Each app card links to its Google Play and Apple App Store listing, where you can check device compatibility, availability, pricing, and the current feature set.

Where can I find support or privacy information?

Visit the dedicated website linked from each app card for product-specific information. You can also email casadozeps@gmail.com. App privacy practices can differ, so check the relevant app's privacy notice and store listing.

Are the apps medical or professional advice?

Happy Poop is a tracking tool, not a diagnostic service or a substitute for medical advice. Movement Pills supports everyday movement and does not replace guidance from a qualified healthcare or exercise professional.
