One app for iOS and Android, built once instead of twice

We build your app in Flutter or React Native, so a single codebase runs on both platforms. You pay for one build instead of two and launch on the App Store and Google Play together.

Quote and schedule after your brief

Who it's for

  • Businesses that need a customer app: orders, bookings, loyalty, personal accounts
  • Startups validating an idea on both platforms without doubling the budget
  • Companies with internal workflows: apps for sales reps, couriers, field staff
  • Owners of a website or online store who want a permanent channel to their customers

Problems we solve

Separate iOS and Android builds cost twice as much

We write one codebase in Flutter or React Native. UI and logic are shared; we only customize per platform where behavior truly differs.

I don't know which framework to pick and I'm afraid of regretting it

At the brief we explain the trade-offs in plain terms and choose for your use case. You get the full source code and repository, so you are not locked in to us.

I'm worried Apple will reject the app

We prepare the build to store guidelines: privacy policy, listing text, screenshots, demo accounts for reviewers. If there is a rejection, we fix the issue and resubmit.

The app lives apart from the website and our systems, so data gets copied by hand

We connect it to your website, CRM and payment provider through APIs. Orders and leads land in your CRM automatically.

How we work

01

Brief and requirements

You describe the task and current workflow. We clarify requirements, choose a first stage and prepare a quote.

02

Prototype and design

We design the screens in Figma and agree on flows before any code is written. Changes at this stage cost the least.

03

Development in sprints

We agree on the schedule after clarifying scope and dependencies. You see progress and can change direction.

04

Testing and release

We test on real devices, prepare store materials and submit the app for review.

05

Pilot with a KPI

We agree on a measurable goal, such as orders placed through the app. We review the numbers together and decide what to build next.

Scope and limits

  • We don't promise top store rankings or a set number of downloads. Installs depend on promotion, not only on code.
  • We don't recommend cross-platform for heavy 3D games, advanced augmented reality or apps tied to unusual hardware. Those often need native development (separate code per platform), and we will say so at the brief.
  • We can't guarantee Apple approval on the first try. We do guarantee we will fix the feedback and resubmit.

FAQ

Flutter or React Native: which one should I pick?

Flutter gives more control over visuals and looks the same on both platforms. React Native fits well if you already have a web team working in JavaScript or React. At the brief we recommend what suits your product.

What do I need to prepare?

A description of the task, examples of apps you like, your logo and brand colors. You also need an Apple Developer account (paid annually) and a Google Play developer account (one-time fee). We register them in your name, not ours.

Who owns the code and the accounts?

We agree on the handover of code, materials and account access before work starts. Third-party licences and services are listed separately when needed.

What does support cost after launch?

We prepare a quote after reviewing your brief. We list support and any third-party costs separately: subscriptions, APIs, hosting or media spend where the project needs them. Provider rates are checked before work starts.

How does payment work?

Payment terms are agreed with the quote before work starts. For a staged project, we describe the result and acceptance criteria for each stage. Support and third-party services are listed separately.

Can I start small and expand later?

Yes. A pilot with one flow and one KPI lets you test demand for less money. If the numbers look good, we add screens and integrations on the same codebase.
