Build

Mobile apps that connect to the systems you already run

Native iOS and Android, or one cross-platform build. For teams who need the phone in someone's hand to talk to the ERP, the CRM or the warehouse system that already runs the business.

What this covers

Mobile apps that connect to the systems you already run, end to end.

Native iOS and Android

Swift for iOS, Kotlin for Android. The right choice when the app depends on the camera, background location, Bluetooth hardware or anything the platform ships first.

Cross-platform builds

One codebase compiled for both stores. Sensible when the app is mostly screens, forms and data from your systems, and you would rather maintain one thing than two.

Integration with your existing systems

Wiring the app into the ERP, CRM, warehouse or booking system that already runs the business. Where there is no usable API, we build the service that sits in between.

Offline and field use

Apps that keep working in a basement, a warehouse aisle or a van. Local storage, a sync queue, and agreed rules for what happens when two people edit the same record.

Store submission and releases

Listings, screenshots, privacy declarations, signing keys and staged rollouts. We handle App Store and Play review, including the rejections, and set up a release process you can repeat.

AI features inside the app

Where an assistant genuinely helps, we build it into the app with guardrails, monitoring and a way to turn it off. The same standard as the agents we put into production elsewhere.

How it runs

Plan. Build. Run.

01

A 30 minute call

You describe what the app is for, who uses it, and which systems it has to talk to. We ask the awkward questions early, because the integrations are what usually decide the cost.

02

Fixed scope, timeline and price

You get a written scope: the screens, the integrations, the platforms, the date and the price. Nothing starts until you have read it and agreed to it. Changes are priced openly, not absorbed quietly.

03

Build, with working builds in hand

We build in increments and put each one on your phone through TestFlight and the Play internal track. You use the real app while it is being made, rather than reviewing screenshots of it.

04

Launch, then run

We submit to both stores under your accounts, watch the first days closely, and then either hand over a documented codebase or keep running the app on a monthly retainer. Your choice, not ours.

Why infoloop

We do not hand over and leave.

  • We stay on after launchMost agencies hand over at submission. That is the point where an app starts needing attention: OS releases, store policy changes, crash reports from devices you do not own.
  • The integration is our problemConnecting to the system that already runs your business is where mobile projects stall. We take that on rather than treating it as your side of the line.
  • One team for the app and the back endThe same people build the app, the API it talks to and the service in between. Nothing gets lost in the gap between two suppliers blaming each other.
  • A price before we startFixed scope, fixed timeline, fixed price, agreed in writing after one call. You are not signing up to an open hourly meter that nobody is watching.
  • You keep everythingYour repository, your Apple and Google accounts, your signing keys. If you move to another team, they can pick the work up without asking us for anything.

What you get

Every engagement includes these, in writing, before work starts.

  • A written scope with a fixed timeline and a fixed price, agreed before any code is written.
  • Source code in your repository, with the build and signing configuration documented.
  • Test builds on your team's phones through TestFlight and the Play internal track.
  • Submission to the App Store and Google Play under your own developer accounts.
  • Documented integrations with every system the app reads from or writes to.
  • Crash reporting, analytics and release monitoring wired in before launch day.

Who this is for

Three situations where this is the right call.

Staff on the floor still work off paper

The back office has an ERP or a job system, and the people in the warehouse, the workshop or the van are filling in forms and typing them up later. A mobile app closes that gap and puts the record in at the point it happens.

Customers keep asking for an app

You have a website that works, and a group of regular customers who want notifications, saved details and one tap to reorder or rebook. An app earns its place when people come back often enough to keep it installed.

You have an app and nobody to maintain it

It was built by a team that has moved on, it has not had an update in a while, and the next OS release will break something. We take over existing apps, work out what is really in there, and either keep it running or plan a rebuild.

Questions

What buyers ask us first.

Should we build a native app or a cross-platform one?
It depends on what the app has to do. Native, written in Swift for iOS and Kotlin for Android, is the right call when the app leans on the camera, background location, Bluetooth hardware or features that arrive with each OS release. Cross-platform, one codebase compiled for both stores, is usually better when the app is mostly screens, forms and data from your systems, because you then maintain one thing rather than two. We recommend one or the other on the first call, and we tell you why.
How much does a mobile app cost, and how is the work priced?
We do not quote a range before we understand the app, because the same number of screens can mean very different work depending on what it has to connect to. The shape is always the same: a 30 minute call, then a written scope with a fixed timeline and a fixed price. You see the number before anything is built, and it does not move unless you ask for something outside the scope. Running the app afterwards is a separate monthly retainer, priced separately, and you are not obliged to take it.
Can the app connect to the ERP, CRM or database we already run?
That is usually the main body of the work. If your system has an API, we integrate against it directly. If it does not, we build a small service that sits between the app and the system and exposes only what the app needs, so the app is never wired straight into a production database. We agree what data moves, in which direction and how often during scoping, and the integration is documented and handed over with the code.
How long does it take to get to a first release?
Nobody can answer that honestly before the work has been scoped. The variables are the number of systems the app has to talk to, whether it needs to work without a signal, and how quickly your team can review builds. We set the date in the written scope after the first call, and then we hold to it. App Store and Play review add time at the end, and we build that into the timeline rather than treating it as a surprise at the finish.
What happens after the app goes live?
A mobile app is not finished at launch. Apple and Google each ship a major OS release every year, and both change store requirements without asking. Our managed service covers monitoring, fixes against agreed response targets, security updates, small improvements, and a monthly report showing what was done and what we recommend next. If you would rather run it yourselves, we hand over the code, the build configuration and the store setup, documented well enough that another team can pick it up.
Who owns the code, and whose developer accounts are used?
You own the code. It sits in your repository from the first commit, not in ours. The apps are published under your own Apple Developer and Google Play accounts, which we will help you set up if you do not have them, so the listings, the reviews and the signing keys stay with you. There is no licence to renew and nothing you have to keep paying us for to keep the app in the stores. If you move to another team later, they get everything without a conversation.
