Custom apps: from idea to store, published and working

We develop mobile applications with their backend, publish them on Google Play and App Store, and stay on to maintain them. Fixed budget by phases, so you know what it costs before you start.

Where app projects get stuck

Almost nobody fails at programming. Custom app projects get stuck on the three things nobody budgets for at the start and that all show up together at the end.

What we develop

We develop custom apps with a clear purpose and a specific user, in any sector. We don’t make “the app for everything,” and you don’t need to have an online store for it to make sense.

Own apps in the stores, not just client projects

The easiest thing in this sector is to promise. We develop and publish our own apps, with their business model built in, and that changes the conversation: when we talk about Google and Apple review, subscriptions, or advertising, we’re talking about something we’ve gone through ourselves, not something read in the documentation.

• Android apps with custom OpenGL rendering
• Backends in Laravel with an operations panel
• Automated image processing
• Subscription with Play Billing
• Rewarded advertising
• Server-side purchase verification
• Signed and published packages
• Scheduled tasks and backups

That means when we tell you a permission will cause problems in review, or that a subscription must be verified on the server and not on the phone, it’s not an opinion: it’s something that has already happened to us and that we’ve already solved. It’s the difference between a team that programs and one that also publishes and maintains.

How we work: four phases, and you come out of each with something

1. Definition · 1-2 weeks

   What the app does, who it’s for, and what it will NOT do in the first version. You get a document with the screens, the fixed scope, and the firm budget. This document is yours even if you don’t continue with us.

2. First version · 6-12 weeks

   The app working with the essentials, plus its backend. You test it yourself on your own phone before it exists in any store.

3. Publication · 2-3 weeks

   Developer accounts in your name, store listings, screenshots, privacy policy, data declarations, and review rounds until it’s approved.

4. Afterwards

   Fixes, version updates when Android or iOS require them, and the features you decide to add. With a monthly plan or by project, whichever you prefer.

Who is it for?

Custom apps pay off when they solve something the web can’t. If your case can be solved with a well-made website, we’ll tell you: it’s cheaper and easier to maintain.

What’s usually behind the app

Almost no app lives alone. The part you don’t see is what decides whether the project moves forward or stays a pretty demo. If you have an online store we connect it, and if you don’t, that’s fine too: most of the apps we make don’t sell products.

If you already have your own server and API, even better: the app connects to what’s there and the budget goes down. We look at that in the definition phase.

What’s included and what isn’t

It’s written down before we start, just like the budget.

Price, payment method and maintenance

The price depends on how many screens it has, whether it needs a new backend or connects to yours, and whether it includes in-app payments. That’s why we say “from”: we prefer to give you a firm figure after the definition phase rather than invent one before knowing what you want.

And it’s worth counting the full cost from the start, not just development: to the initial investment you have to add Google’s developer fee (€25 one time) and Apple’s (€99 per year), the server, and the maintenance we talk about just below. We’d rather you know now than be surprised in month thirteen.

• Fixed budget, no open-ended hours
• Phased payment, not all upfront
• The code and accounts are yours
• If we don’t see the project fit, we’ll tell you

And after that: maintenance

Custom apps are not delivered and forgotten. Google and Apple raise the minimum level they accept every year, and an app that doesn’t update its version can no longer be updated in the stores until it disappears from them. It’s worth knowing what you’re committing to before you start, not at the end:

The 30 days of fixes after publishing are included in the project, with or without a plan. The monthly plan starts when they end.

Frequently asked questions

Android and iOS, or just one?

Both, with a single codebase. If your audience is clearly on one platform, starting with one and adding the other later is cheaper and lets you launch sooner. We decide that in the definition phase with your data, not by default.

How long does it take?

Between two and four months to have it published, including the store review rounds, which are outside our control. The definition phase takes one or two weeks and is what most affects the real timeline.

Who owns the app when it’s finished?

You do: the code, the developer accounts, and the data. No strings attached. If one day you want another team to handle it, you hand it over and that’s it.

Can you connect it to my store or ERP?

That’s one of the things we do most. We’ve spent years syncing WooCommerce and PrestaShop with ERPs and suppliers, so the integration part is familiar territory.

What if my idea doesn’t need an app?

We’ll tell you in the first reply. Many ideas are better solved with a well-made website: it costs less, is cheaper to maintain, and doesn’t depend on two companies approving every update.

How much does it cost to maintain the app once it’s published?

From €190 per month with a plan, which covers mandatory version updates, bugs, backend monitoring, and store listings. Without a plan, each intervention is quoted separately: it’s cheaper in the first year and quite a bit more expensive from the second, because the mandatory updates still come. The 30 days after publication are included in the project either way.

What happens when Android or Apple change the requirements?

Every year they raise the minimum level and you have to upload a new version or the app stops being updatable. That’s included in the maintenance plan; without a plan, it’s quoted when needed.

Tell us your idea

If you’re considering custom apps for your business, you don’t need to bring a fully formed idea. Just tell us what problem you want to solve and for whom, and we’ll give you an initial assessment of whether it makes sense to build an app and where the budget would go.
