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 we bring

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.

The problem

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.

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

AI-Native Developers.

Not every project needs the same people. You work with a small team of specialists that flexes based on the project. That way we can scale up and down while keeping quality high. Sion always holds the architectural responsibility, because he's a developer himself. Through his network he brings in the right people where needed.

Frequently asked

What clients often ask about apps.

Don't see your question? Ask in a video call.

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