App developmentfor iOS and Android

Apps for the people who don't work at a desk: drivers, field reps, technicians filing a report on site. You see a working demo of your case before you pay anything.

Which kind of app. We decide before the quote, because it's what moves the price most.

Native

Apps that use the phone hard. Camera, location, Bluetooth and offline work all day. Swift and Kotlin only when performance or a brand-new OS feature requires it.

Cross-platform

One codebase for iOS and Android. With React Native or Flutter. It's our default when you need a real app in both stores.

Web and PWA

A web app that works like an app. For occasional mobile use: portals, lookups, approvals. A PWA installs on the home screen and sends notifications, without going through the stores.

Stores

Publishing and new releases. We prepare it for App Store and Google Play review and document how the next release gets published.

What you keep. The app is yours, published under your accounts.

  • The code

    For the app and the web dashboard, in a repository in your name.

  • The accounts

    The app is published under your Apple and Google developer accounts, and the backend runs in accounts you own.

  • The documentation

    Store listings —copy, screenshots and icons— and the release process step by step.

  • The guarantee

    If the app doesn't work for you, you get your money back. We carry the estimating risk.

What's included. And what isn't, in writing before we start.

Included

  • An iOS and Android app from one codebase, unless there's a reason to split them
  • Offline mode, syncing when the connection comes back
  • Camera, location and push notifications where the workflow needs them
  • The web dashboard where you see what the apps capture
  • Publishing to the App Store and Google Play
  • Store listings: copy, screenshots and icons

Not included

  • Apple and Google developer accounts: in your name, with their own annual fees
  • What the stores decide in review: we prepare the app to pass it, but can't guarantee their timeline
  • Versions for operating systems the vendor no longer updates
  • Keeping the app live forever: the stores require periodic updates, and that's maintenance

Apps we've built. Each one with a demo you can click through.

How we work. From the first call to an app in the stores.

Step 01

Demo on your case

On the first call we look at who will use it and where. Within 24–48 hours you get the main screens to click through, free.

Questions about apps. The ones we get before the first meeting.

At Atomix, an app runs USD 5,000 to 10,000 depending on scope: native, cross-platform or web, how many user roles, and whether it needs offline mode or payments. Only exceptional, much larger projects go above USD 10,000. The price is fixed in writing before we start.

You need an app if the work has to continue without signal, uses the camera, GPS or Bluetooth all day, depends on notifications, or gets opened many times a day. If none of that applies, a well-built mobile web app costs less and nobody has to install anything.

The demo takes 24–48 hours. A store-ready app takes under a month for most projects. How long Apple and Google take to review is up to them: we prepare the app to pass, but that timeline can't be guaranteed.

You do. The app is published on the App Store and Google Play under your developer accounts, the infrastructure is in your name, and you keep the code for the app and the dashboard.

Yes. We're based in Argentina, one to five hours ahead of US time zones depending on the coast and the season, so our working day overlaps yours. Weekly demos and calls happen in your hours.

The stores require periodic updates and the operating systems change every year, so a published app needs maintenance. It's optional and separate from the build, monthly or per job.

Does any of these look like what you need?

Half an hour, free, to understand what you need. If we can build it, you leave the call with the scope, the timeline and the price; if we can't, we tell you right there.
