Software & App Studio

Software with a purpose.

We build products that earn their place. Excellent in craft, bold in ideas, powerful where it counts.

01 / Purpose

Every product needs
a reason to exist.

We start there. Find the human need, then bring three things to everything we ship.

Excellence

Every detail is a decision. We sweat the pixels, the frame rate and the edge cases, so the product feels inevitable.

Creativity

Fresh ideas, built right. We begin with what people actually need, then explore the paths nobody has tried yet.

Power

Engineered to perform. Native, fast and secure, with room to grow from first prototype to a product people rely on.

02 / Launches

Our apps.

Shipped, and on the way.

Mobile apps

Native iOS with Swift and SwiftUI, and Android with Kotlin and Jetpack Compose. Designed, built and shipped end to end.

AI-powered features

On-device vision, language and recommendation features that feel like part of the product, not a bolt-on.

Senior engineering

Hands-on help for teams: modernizing legacy codebases, raising quality, and owning a feature from spec to release.

05 / Origin

About JayPi.

JayPi is a small studio founded by João D'Avila, a senior software engineer with 8+ years of experience in mobile, AI and games. We keep the team small and the standards high, so every app we ship is something we would want on our own phones.
