Mobile App Development Services
Native and cross-platform apps, designed, built and released.
Field apps, customer apps, and the ones that have to keep working with no signal.
The first question is always whether an app is even the right answer. A mobile site does most of what people ask for. An app earns its cost when it needs the camera, the location, notifications, or has to work where there is no coverage.
Our crews fill in paper in the field
Inspections, job sheets and photographs captured on a phone and synced when signal returns. This is the single most common app we are asked for, and the one with the clearest return.
Customers want an app and we are not sure they need one
We will tell you when a mobile site does the job. When an app is right, one codebase across iOS and Android is usually the correct economics, and we will say when it is not.
It has to work with no signal
Offline behavior designed up front: what gets cached, what queues, and what happens when two people edited the same record. Discovering that after launch is expensive.
Our app was rejected by the App Store
We handle submission, including the parts that get apps rejected, and the ongoing releases that keep them from being pulled a year later.
You get an honest answer on native against cross-platform, what the first release should contain, and a range. Including the answer that you do not need an app.
What a mobile build involves.
We work out whether you need two native apps or one cross-platform build. Cross-platform saves money until you need deep device features, and then it does not.
What the app has to do, who uses it and how it connects to your existing systems, decided before the estimate. A mobile app that duplicates your website rarely justifies its cost.
A working prototype you can hold before the full build, because reading a specification tells you much less than tapping through the thing.
Tested across real devices and OS versions, on hardware we keep for it.
App Store and Play Store submission, review requirements and the rejections that come with them, handled by us.
Apple and Google change requirements every year. An app nobody maintains stops working, so we keep it current or hand you what you need to.
The apps clients bring us.
For people working away from a desk: jobs, photos, signatures, checklists. Usually the ones that most need to work with no signal.
Booking, account, loyalty or order tracking, for businesses whose customers open a phone rather than a laptop.
Internal apps for people on the move, connected to the systems already running back at the office.
Availability, reminders and rescheduling, synced with whatever calendar or system already holds the truth.

Work captured without a connection and reconciled when one returns. Harder than it sounds and the reason a lot of field apps get abandoned.

App Store and Play submission, the review requirements, and the yearly OS changes that break apps nobody maintains.
React Native, in production.
Straight answers.
Native or cross-platform?
React Native for most business applications. Native when you need deep platform features or sustained high-performance graphics.
Do you publish to the App Store for us?
Yes, under your developer accounts so you own the listings.
Can the app work offline?
Yes, if it is designed for it from the start. Retrofitting offline support is expensive, so we settle it early.
What about ongoing releases?
OS updates break things on a schedule. coreAssist covers keeping the app current.
