Mobile apps for iOS and Android

We build mobile apps for iOS and Android from a single codebase, for companies that want to reach customers, members or staff on their phones: apps for subscription services, calculation and monitoring tools, customer areas, bookings and notifications. We design the interface and the backend, the part that handles data and users, publish it on the App Store and Google Play and look after it for years, as we do with our own. From €12,000 to over €35,000 excluding VAT, in 2–4 months.

Apps for companies and startups in Italy and abroad, developed remotely from first contact to the store release.

Why KVA

An app people use every day

A mobile app makes sense when the phone is where your service is actually used: a subscriber checking live data, a customer booking or receiving a notification, a technician filling in a form on site, a member logging in to their account. In mobile app development the first question is therefore a simple one: what must the user do in thirty seconds, with one hand, while doing something else. The screens come from there, and only then the technology.

We build apps for iOS and Android from a single codebase, so design, features and updates stay identical on both systems and costs do not double. The backend is shared with your website or web app: data, users and subscriptions live in one place. We also publish four apps of our own. Prop Trading Stat tracks prop-trading fees, payouts and ROI, with in-app subscriptions; Forex Sentiment shows sentiment on 29 markets and sends signal notifications. Forex Pip Calc works out pips, lot size and margin; Futures Tick Calc, tick value and profit and loss on futures. So we know first-hand what it takes to pass store review, handle subscriptions and in-app purchases and keep an app current with every new version of the operating systems.

We work fully remotely and internationally: remote analysis, a written functional specification, a clickable prototype, a preview of the app on your phone at every release, publication on the app stores under your company's name.

Method

How we work

  1. 01

    Analysis

    A first conversation about who will use the app, what it must do, which data and systems it must talk to and whether a web version is also needed. Then a written functional specification and a clear quote.

  2. 02

    Prototype

    Screens and flows in a clickable prototype you try on your own phone: you approve it before development starts and already know what the app will be like.

  3. 03

    Build

    Every few weeks a new test build to install on your team's devices; meanwhile we build the backend and APIs and test them with real data.

  4. 04

    Stores and growth

    Release on the App Store and Google Play under your company's name, monitoring, updates for new iOS and Android versions; new features are quoted before each release.

Indicative prices

What a mobile app costs

Indicative prices, excluding VAT. Each app is quoted on its own functional specification: screens, integrations, backend and post-launch services. You get the quote a few days after the analysis, with no obligation.

FAQ

Common questions

Before building an app, companies and startups mostly ask us about costs and timing, iOS and Android, the stores, the backend and maintenance.

Another question? Write to us

How much does it cost to develop a mobile app?

An iOS and Android app usually costs from €12,000 to €35,000 excluding VAT and takes 2–4 months; with many integrations or a complex backend it can exceed this range. The quote is based on a written functional specification, so you know in advance what you will get. To spend less at the start, you can release a first version with only the core features and add the rest later.

Should I build for iOS and Android at the same time?

Yes, in most cases: we build from a single codebase, so the second platform does not double the cost and the two apps stay identical at every update. Starting with one system only makes sense when almost all your users are on one platform, for example an internal app installed on company devices.

Is a mobile app or a web app better?

It depends on where and how it will be used. An installed app is at its best when you need push notifications, offline use, the camera and sensors or a presence on the app stores. For management software or a customer area used mostly on a computer, a web app costs less and needs no installation: it is the starting point we recommend most often. In many cases the answer is both, on the same backend: that is how Prop Trading Stat and Forex Sentiment were born.

How long does it take to publish an app?

Usually 2–4 months from approval of the functional specification, with test builds every few weeks on your team's devices. Store review takes from a few days to a couple of weeks: we put it in the schedule from the start, together with the materials the stores require, such as the privacy notice, screenshots and descriptions.

Will the app be published in my name?

Yes. The app is published on the App Store and Google Play with developer accounts registered in your company's name, so your brand appears on the app stores and the user data stays yours.

Do I also need a backend? Can I use my website or web app?

An app almost always needs a backend: users, data, subscriptions, notifications. If you already have a website or a web app, the app can use the same data through dedicated APIs. Otherwise we design the backend and the admin panel together with the app and host them on our European server, with backups and monitoring covered by the yearly fee; if you prefer your own infrastructure, the fee does not apply and maintenance is agreed separately, with its own quote.

Who handles updates after launch?

We do, if you wish. Every year iOS and Android change rules and requirements and the stores ask for updates: monitoring, fixes, compatibility updates and support are covered by a fixed yearly fee set in the quote. New features, on the other hand, are quoted separately before each release.
