Services / Mobile applications

Your app,
in your customer's pocket.

I build mobile apps for iOS and Android from a single codebase: fast, clean and shaped around how people actually use a phone. From the idea to the App Store and Google Play, with everything that takes along the way.

From me

Sarghy, founder of Sarghy Design

A badly thought-out app gets deleted on day one. Slow, heavy, menus you get lost in, notifications that irritate. The phone is the most personal screen a person owns, and it has no patience for anything that gets in the way.

I don't squeeze your website into an app. I build something fast and clear, shaped around how someone holds a phone, from one codebase that runs on iOS and Android at the same time. So your app stays on the screen instead of going in the bin.

Why it matters

What actually kills most apps

01

The first impression is the only one

On mobile there is no second chance. If the app is slow or confusing the first time it opens, people close it and delete it. Speed and clarity are not polish, they are the condition for staying installed.

02

Two platforms, double the budget — or not

Done the wrong way, an app means building and maintaining everything twice, iOS and Android. Done the right way, one codebase covers both — far less to build and, more importantly, far less to maintain for years.

03

The app is only the tip

What you see on the phone sits on a backend, notifications, accounts and updates. An app is a whole system; if the foundation underneath is weak, you feel it in your hand immediately.

What I do

What I build, piece by piece

Everything that goes into a mobile app that stays on the screen. One at a time.

iOS & Android

One codebase (React Native / Expo) that runs on both. The same app, for far less effort and cost than two separate native apps.

Development & UX

An interface built around how you actually use a phone: gestures, smooth movement, clear screens. Quick and pleasant to use, not a website squeezed into a frame.

Push notifications

Notifications that bring people back without annoying them. Used with judgement, they are the best reason someone opens the app again.

Accounts & backend

Sign-in, data, syncing, everything sitting behind the screen. An app is worth as much as its foundation, not just the part you can see.

Publishing to the stores

I handle everything to do with the App Store and Google Play: requirements, rejections, release. The bureaucratic part everyone hates.

Security & updates

Protected data, and updates as the stores change their rules. An app nobody maintains quickly becomes an app that stops working.

How I work

From idea to a published app

  1. 01

    Discovery

    I work out the idea, the users and what the app has to do. What earns a place in the first version and what can wait.

  2. 02

    Design & flow

    I design the screens and the flow, for mobile. How someone moves through it, where they tap, what they see first.

  3. 03

    Build

    I build the app in stages, backend included. You watch the progress on your own phone instead of waiting months in the dark.

  4. 04

    Testing

    I test on real devices, iOS and Android. What works on mine has to work in your customer's hand.

  5. 05

    Release

    I publish the app to the stores and stay on for updates and new features. Launch is the start, not the end.
