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.

How We Work

A 4-week first release commitment

Define the problem fast, then move with small, sharp steps until launch.

  1. Week 1

    Discovery & Strategy

    Short workshops, user interviews, and a written scope.

  2. Week 2

    Design Sprints

    From wireframe to clickable prototype — daily reviews.

  3. Week 3

    Development

    A working build on TestFlight / Internal Testing.

  4. Week 4

    Launch

    App Store and Google Play submission, with launch-day support.

Portfolio

One app, lots of attention. We ship deliberately — quality first, then scale.

Dark Village

iOS · TestFlight 4.8 ★ in beta

A moody, narrative survival village builder. Lead a handful of survivors through the long nights — gather resources by day, light the watchfires by dusk, and protect your people from whatever stirs in the woods. Hand-crafted dark-fantasy art, ambient audio, and short, meaningful sessions designed for mobile.
