Mobile apps in both stores, in weeks.

Cross platform builds for iOS and Android at once. Push, offline-first, in-app subscriptions and App Store compliance.

  • iOS + Android
  • One codebase
  • Rapid development

Consumer apps

Apps for your end customers with onboarding, accounts and social sign-in. Ready for the App Store and Play Store.

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 via Stripe.

Offline-first

Apps that also work without internet. Local storage, sync as soon as you are back online, no data lost.

Recent work

An app we built recently.

Real numbers, no demos.

Challenge

A live network platform that, as a startup, has to iterate fast. AskTippi needed a steady technical partner who not only maintains the platform but sharpens it and grows with what the market asks for.

Approach

We got up to speed on the existing platform, improved the current flows and set a rhythm that lets us ship fast. Now we are extending the Cloudflare backend and building a mobile app, so AskTippi sits natively in the user's hand too.

Outcome

A platform that moves faster than before, a backend that scales with it and a mobile app on the way. Short lines, quick iterations, a steady partner who knows the product.

Engagement

The team

Senior developers, AI as the accelerator.

We are a small, senior team based on the Herengracht in Amsterdam. You work directly with the developer building your app, no middle layer, no delay.

Our approach

Full-stack: the right choice per project.

No fixed stack, but a deliberate choice. For each app we pick the tools that fit your users, features and timeline. A few examples.

One app for iOS and Android

Expo and React Native: one codebase that ships to both stores at once, with no compromise on UX.

Push, accounts and payments

Firebase or Supabase as the backend, in-app purchases with server-side validation, and targeted push notifications.

Offline or heavy functionality

Local storage with sync, native modules where they are truly needed, and a backend that scales with your users.
