Mobile apps that make it through the stores

The most expensive mistake in a mobile app is not in the code — it is in the scope. We start with a version you can ship and measure, then build out only what people actually use. We publish our own apps, so we also know the part nobody talks about: App Store and Google Play review.

What we do

From a single-platform MVP to a product with an admin panel, payments and client-side integrations. We pick the technology for the budget and the product’s lifespan, not for fashion.

01MVP firstThe smallest version that makes commercial sense: a few screens, a backend, authentication and store publishing. It exists to gather data from real users before you spend the next hundred thousand.
02iOS and Android from one codebaseA shared codebase when you want both platforms on a single budget. Where it matters we drop to native — maps, camera, high-performance lists, deep system integration.
03Native appsSwift and Kotlin when the product leans hard on hardware or must stay smooth with large data sets. We choose this route deliberately, not out of habit.
04Backend and admin panelThe app is usually a third of the project. The rest is the API, database, roles, notifications and a panel where your team manages content and users without a developer.
05Store publishing and upkeepDeveloper accounts, listing assets, privacy policy, data declarations, responses to rejections. We keep shipping updates for new OS versions, without which an app quietly stops working.
06Analytics and post-launch growthEvents named so you can actually read behaviour: where users drop off, what they turn on, what they ignore. We plan the next features from that data, not from a wish list.

What an app actually includes

The things clients usually discover mid-project — with us they are costed from the start.

01Authentication and accountsEmail, phone, Apple, Google. Roles, permissions and account deletion compliant with both stores’ requirements.
02Payments and subscriptionsIn-app purchases, subscriptions with trials, refunds and purchase restoration. Plus external payments where store rules allow it.
03Push notificationsSegmentation, campaigns and event-triggered messages — measured, so you know how many actually bring the user back.
04Offline modeWorking without a connection and syncing on return, with conflict resolution. Essential in the field, in warehouses and on production floors.
05Integration with your systemsERP, CRM, warehouse, telephony. An app is rarely standalone — usually it is the front end of a process you already run.
06Security and GDPRData encryption, secure token storage, consent handling and user data export. Infrastructure in the EU region by default.

How we run it

Four stages — from scope to an app live in both stores.

01Scope and platformsA free 45 minutes on who will use it and why. We decide what goes into version one and what is deliberately deferred — the single biggest cost lever in the whole project.
02Screens and fixed priceA clickable prototype of the key flows and a fixed quote within 3 working days. Changes at this stage cost minutes, not weeks.
03Build and test versionsEvery two weeks you get a build on your phone via TestFlight and the Google Play testing track. You test on your own device, not on a recorded demo.
04Publishing and 90 days of supportListing preparation, passing review in both stores, crash monitoring after launch, and fixes included in the project price.

How we know this

We publish our own apps and go through store review ourselves — rejections included.

Frequently asked questions

Cost, time, and what happens after launch.

How much does a mobile app cost?

Mobile apps start at 8,100 PLN net with us. That is a realistic MVP scope: one platform or a shared codebase for iOS and Android, a handful of screens, a backend and store publishing. A larger product with payments, offline mode, an admin panel and integrations is usually 30,000–120,000 PLN. The biggest price drivers are the number of screens and whether the app has to talk to your systems.

How long does an app take?

An MVP is typically 8–12 weeks from kickoff to publication; a larger product runs 4–6 months. On top of that comes store review: Apple usually takes 1–3 days, but a first submission often comes back with notes, adding another cycle. We build that margin in upfront so the launch date is realistic.

Native or one codebase for both platforms?

A shared codebase makes sense for most business apps — you get both platforms for close to the budget of one, and users will not notice the difference. We go native when the product leans on hardware, needs maximum smoothness with large lists, or integrates deeply with the OS. We recommend after discussing the features, not upfront.

Do I need a separate backend?

Almost always. The app is the interface; data, accounts, notifications and the admin panel have to live somewhere. Our quote includes the backend from the start — that is a common reason competing offers look cheaper and end in a surcharge.

Who handles App Store and Google Play publishing?

We do. We set up or configure developer accounts under your company, prepare descriptions, screenshots, privacy policy and data declarations, then run the submission through to approval. The accounts stay yours — which matters if you ever change supplier.

What if Apple rejects the app?

That is a normal part of the process, not a failure. The most common reasons are missing account deletion, an unclear subscription description, or a feature the reviewer cannot reach. Fixes after a rejection and resubmission are included in the project price — we do not bill them separately.

What does upkeep cost after launch?

The app does not break on its own, but the systems around it change: new iOS and Android versions ship every year and the stores raise their requirements. Budget for a few technical updates a year. We can run that on a retainer or hourly — your choice.

Do I get the code and the accounts?

Yes. Once the project is settled we transfer full economic rights to the code, the repository, backend access and the App Store Connect and Google Play Console accounts. Nothing stays on our side.
