How long does it take to build an app?

Weeks, not months. A first working version is usually ready within 6 to 10 weeks, depending on complexity. We work in weekly steps with demos, so you see the app take shape as we build.

Do you build for iOS and Android at once?

Yes. We build one app that works on both iPhone and Android, so you do not pay for two separate apps. We make sure everything works and looks right on both.

Do you publish the app to the App Store and Play Store?

Yes. We handle the full submission process, from registration to review by Apple and Google, including everything required such as the privacy policy. Updates for new iOS and Android versions can stay with us afterwards.

Everything a real app can: notifications, camera, payments and subscriptions inside the app, and use without internet if you need it. The code is entirely yours.

Challenge

AskTippi puts your network to work: post a question, attach a reward and let it travel through contacts to the right person. The platform was already running on web, but a network product belongs natively on your phone, with push notifications and a share flow that works in seconds.

Approach

A native app built with Expo and React Native on the existing Cloudflare backend. Sign in with Apple, Google or SMS, a feed with questions and rewards, safe tipping and payouts in the app, and a share flow to WhatsApp that keeps the chain going.

Outcome

The app is live in the App Store and keeps evolving in the same rhythm as the platform: short lines, fast releases, a steady developer who knows the product.

What every app ships with by default.

Cross platform with Expo and React Native. One codebase, two stores, no compromises on UX.

Native iOS & Android
One codebase for both stores, with onboarding, accounts and social sign-in. A native feel, not a half-baked hybrid.
Push & notifications
Targeted push notifications, in-app messages and email campaigns via Firebase, Resend or your own backend.
In-app subscriptions
Apple and Google in-app purchases with server side validation. Or your own subscription flow.
Offline-first
Apps that also work without internet. Local storage, sync as soon as you are back online, no data lost.

Building an app often goes wrong.

Two separate codebases, projects that drag on for months and store reviews that hold up your launch. These four points are where it stalls, and how we turn it around.

Why app projects stall

How we approach it

Everything gets built twice
A separate iOS team and a separate Android team means double the code, double the bugs and double the cost. You build and maintain every feature twice.
One codebase, two stores
With Expo and React Native we build for iOS and Android at the same time. Native modules where it genuinely matters, shared code where it makes sense, and one release flow for both stores.
A project takes months
At a traditional agency you easily spend half a year from briefing to store, with invoices running long before anything is in the hands of users.
In the store in weeks
AI-native development with senior developers: shorter timelines and lower costs. You have a working app sooner, one you put in front of real users and adjust as you go.
The store review holds you back
Rejections over privacy policies, account deletion or in-app purchase rules can delay your launch by weeks if you don't know Apple and Google's rules.
We handle compliance
We take care of submission, review rounds, privacy policies and all store requirements. Including in-app purchases and account deletion, so your launch doesn't stall.
A hybrid app feels cheap
Many low-code and webview apps feel slow, don't work offline and lose data the moment the connection drops. Users notice immediately.
A native feel, offline too
Smooth, native interfaces with local storage and automatic sync as soon as you are back online. No data lost in the elevator, the train or the car park.

The team.

We think along on what you want to achieve, and we build it too. Everyone on the team has their own discipline and expertise, and we bring those together per project. You talk directly to the people doing the work.

What clients often ask about apps.

Don't see your question? Send a message.

It depends on the project. The price comes down to the complexity, the number of screens and the features you need. In a first call we scope it out together, then you get a quote. No surprises afterwards.

An app idea you want to build?

You tell us what you have in mind, we tell you honestly whether and how we can help. No sales talk, no obligations.
