Revryn

We design and build web and mobile apps that last.

Revryn is a product engineering company. One team takes your product from the first screen to the servers it runs on, and stays with it after launch.

Where we come in

We’re most useful at three moments.

  1. When a product needs to exist.
  2. When it has outgrown the way it was built.
  3. When the roadmap needs more hands than the team has.

Work

Selected work

A selection across web, mobile and backend work.

Snipr

An offline code snippet vault for iOS and Android, built on an on-device SQLite database. It reads code out of screenshots and explains or improves snippets with the developer’s own Gemini, Claude or OpenAI key, kept encrypted on the phone.

Mobile application React Native, Expo, SQLite

Drivewise

A driving safety app for iOS and Android that reads the phone’s accelerometer, gyroscope and GPS to catch harsh braking, sharp turns and phone handling as they happen. Each drive ends with a score out of 100, and the history stays on the device.

Mobile application React Native, Expo, TypeScript

Clients

In their words

“We always knew where the project stood. Deadlines were met without us having to chase anyone.”

Services

Design and engineering, under one roof

The people shaping the product are the people building it. Decisions hold up because nobody has to translate them.

Stack

What we build with

Every choice comes down to how it behaves in production: speed, failure modes, and how easy it is to hand over.

  1. Interface

    Web

    React for interfaces, rendered on the server with Next.js so pages arrive fast and index well. TypeScript on every line.

    Mobile

    React Native for one codebase across iOS and Android. Kotlin when a feature has to be fully native.

  2. Product logic and APIs

    Backend

    Go for services that must stay fast and predictable under load. Node.js when a team wants one language from browser to server.

  3. Data

    Databases

    PostgreSQL for relational data and anything that needs transactions. MongoDB for document-shaped data that changes often.

Approach

How a project runs

Five stages, in order. Each one ends with something you can see and check.

  1. 01

    Understand

    We start with the problem, not the feature list. Who uses it, what exists today, and what success looks like.

    OutputA written brief both sides agree on

  2. 02

    Define

    We shape the product before building it. Flows, key screens and a technical plan, checked with real users where we can.

    OutputPrototype and architecture outline

  3. 03

    Build

    Short cycles with working software at the end of each one, running somewhere you can use it.

    OutputWorking software, reviewed as it’s made

  4. 04

    Refine

    Testing, performance, accessibility and edge cases. The unglamorous work that decides whether software holds up.

    OutputA product ready for real traffic

  5. 05

    Ship

    Launch is a handover, not an exit. Monitoring, documentation and support after release.

    OutputA live product your team can own

About

We’d rather build it right than build it twice.

Most software doesn’t fail loudly. It gets slower to change, harder to trust and more expensive to run.

We work to prevent that from the first week. That means understanding the problem before writing code, keeping systems simple enough to change, and caring about the details people only notice when they’re missing. We want long-term work with teams who care how their product is built, not only how it looks.

  • Clear over clever

    Code, interfaces and decisions should be easy for the next person to follow.

  • Less, but finished

    Fewer features that work completely beat many that almost do.

  • Built to hand over

    Documented, tested and readable. You should never be locked in to us.

  • Straight answers

    If something is a bad idea, a risk or running late, you hear it early.
