How much does it cost to build a mobile app?

A fixed price, quoted after a 30-minute scoping call — no hourly billing. The quote covers a written scope and a delivery date agreed before the build starts.

How long does it take to build a mobile app?

Six weeks at most to a first working version on a real device, with a working demo every week as it comes together.

Do you build for both iOS and Android?

Yes — iOS and Android, for field teams who need the app to work away from a desk and for customers using it on their own phones.

Can the app connect to the systems we already run?

Yes. The app is built to talk to the systems you already have, so what happens in the field lands where the rest of the business can see it.

Yes. You own the code and the store accounts at handover.

Mobile App Development Agency

Havoric is a mobile app development agency building iOS and Android apps for teams in the field and customers on their phones — simple to use, quick to ship, and connected to the systems you already run. Fixed quote, weekly demos, and you own the code at handover.

What we build

Field-team apps — inspections, deliveries, site reports, and job sheets captured on a phone instead of on paper that gets typed up later.
Customer-facing apps — ordering, booking, and status tracking for the customers who live on their phones.
Companion apps — the mobile end of a web application or an AI automation pipeline: approve a flagged invoice from your phone, snap a document straight into the processing queue.

How a mobile project runs

The same way everything at Havoric runs: a 30-minute call, a written scope with a fixed price and delivery date, working builds on your own phone every week, and a handover where the code, the app-store accounts, and the backend are all yours. First working version in six weeks at most.

Cross-platform or native

Decided from your app, not from a preference. Cross-platform suits apps that are mostly forms, lists and sync, need both platforms, and will be maintained by a small team. Native earns its cost when you lean on the device — sustained camera work, background location, Bluetooth peripherals — or when one platform genuinely covers your users, which is common for internal apps on company-issued phones.

We settle it on the first call with four questions about the app, and occasionally the answer is that you do not need an app at all: a mobile-friendly web application covers more cases than people expect, with no store review in the loop.

What makes a field app get used

This is where most field apps fail, and it is rarely technical.

It has to work with no signal. Basements, plant rooms, lifts and rural routes all break connectivity. An app that needs a connection to submit gets tried twice and abandoned. Offline-first means the job completes on the device and syncs when a signal returns — which makes conflict handling the real engineering problem, not the interface.

It has to be faster than the clipboard. A crew doing twelve jobs a day will not tolerate a form designed by someone who filled it in once. Most of what is on the paper version is already known and can be prefilled.

It has to give the crew something back. An app that only serves the office gets completed on Friday from memory, which is worse data than the paper it replaced. What we have learned building these covers the rest.

One backend, every screen

Mobile apps rarely stand alone — they share a backend with the web tools and automation behind them. Because we build all three, you get one system and one handover instead of three vendors pointing at each other. The backend side of our work runs on Python and SQL; the review-queue post ships the real code and schema.

At handover the code, the app-store accounts and the backend are all yours.

When we would tell you not to build an app

The process happens weekly. A mobile-friendly web page does the job, and there is no store release sitting between you and a fix.
Nobody can name the task it makes faster. “We should have an app” is not a requirement, and an app without a job does not get opened twice.
You need to iterate quickly. Store review puts days between a bad assumption and its correction. Sometimes that is worth it; often it is not, and it should be a decision rather than a surprise.

If one of those describes your situation we will say so on the first call, the same way half our automation calls end with “not yet”.

Book a call — 30 minutes, no pitch deck, and an honest answer on whether an app is the right first build.
