Notion Tech designs and builds mobile apps for iPhone and Android with React Native and Expo, so one team ships both. We handle the App Store and Google Play process too: the Rostery worker app is live on both stores and used on shift every day.
iOS + Android
from one codebase
Both stores
Rostery app live

and GPS ready
Fast, simple and reliable, on every phone your customers use.
Booking, ordering, loyalty and account apps that make repeat business easy.
Clock in and out with GPS, shift notes, checklists and photos, even with poor signal.
Mobile versions of your web platform that share the same accounts and data.
Reminders, alerts and updates that bring people back at the right moment.
Card, Apple Pay and Google Pay through Stripe, set up correctly for Australia.
App Store and Google Play listings, reviews and updates handled for you.
React Native and Expo let us build one app that runs natively on iPhone and Android. That means one team, one set of features and one release schedule, which usually costs far less than two separate native apps, without the clunky feel of older hybrid apps.
Where an app needs something special from the phone, such as background location, the camera or offline storage, we use native modules and test on real devices, not only simulators.
Getting an app approved by Apple and Google is part of the job. We prepare the listing, privacy answers, screenshots and review notes, and we deal with feedback from reviewers. The Rostery worker app is live on both stores and receives regular over-the-air updates without waiting for a full review.

A simple app with a few screens costs much less than an app with accounts, payments, maps and an admin system. We quote a fixed scope in AUD after a short discovery session. Our pricing guide explains how we price.
Mostly cross-platform with React Native and Expo, which gives native performance on iPhone and Android from one codebase. We add native Swift or Kotlin code where a feature needs it.
Yes. We set up the App Store and Google Play listings, answer the privacy questions, handle review feedback and publish updates.
Yes. We store data on the phone and sync it when the connection comes back. The Rostery worker app is built this way.
