About

Small team.
Big craft.

Str4toX Studio is an independent studio of designers and engineers who have spent years shipping mobile products. We publish our own apps, and we take on client work only for projects we genuinely believe in.

Our philosophy is simple: speed, clarity, and craft. Every line of code, every pixel, every screen — a promise to the user.

What We Do

Everything you need to ship a mobile product

From the first concept session to launch day — owned by a single, focused team.

01

Product Strategy

Target users, problem space, MVP scope, and a measurement plan you can act on.

02

UI / UX Design

Dark-first, fast, and clear interfaces. Fully prototyped in Figma.

03

iOS & Android Development

Swift, Kotlin, and React Native. Tested, scalable codebases built to last.

04

Backend & Infrastructure

Auth, push, payments, analytics — managed cloud services, ready out of the box.

05

App Store Launch

ASO, screenshots, review process, and release management end-to-end.

06

Growth & Maintenance

Continuous iteration, A/B testing, and a tight feedback loop with users.
