Mobile app development services

From the first concept to the app store and beyond. Choose the part you need, or let us handle the whole project.

  • Android App Development for Small Businesses

    Android app development is building apps for Android phones and publishing them on Google Play. Apptavio builds Android apps for small businesses with React Native, Expo and TypeScript, sharing one codebase with the iPhone version.

  • API Integration: Connect Your App to the Systems You Already Use

    API integration connects your mobile app to systems you already run — booking software, online shop, CRM, point of sale or payments — so data stays in one place. Apptavio checks feasibility first, because every integration depends on what the other system's API allows.

  • Booking App Development for Appointment-Based Businesses

    A booking app lets your customers see availability, book, reschedule and get reminders from their phone. Apptavio designs and builds custom booking apps for iPhone and Android, and shows you a free interactive concept based on your website before you commit.

  • Custom Mobile App Development for Small and Medium-Sized Businesses

    Custom mobile app development means designing and building an iPhone and Android app around how your business actually works. Apptavio builds them for small and medium-sized businesses, and shows you a free interactive concept first.

  • E-commerce App Development for Independent Online Shops

    An e-commerce app gives your regular customers a faster way to browse, reorder and pay from their phone, connected to the online shop you already run. Apptavio builds custom shopping apps for iPhone and Android and shows you a free interactive concept first.

  • iOS App Development for Small Businesses

    iOS app development is building apps for iPhone and iPad and publishing them on Apple's App Store. Apptavio builds iPhone apps for small businesses with React Native, Expo and TypeScript, so the same app can also run on Android.

  • Mobile App Design: UX and UI for iPhone and Android

    Mobile app design is the work of deciding what your app does, how customers move through it and how every screen looks. Apptavio designs iPhone and Android apps that follow platform conventions, reflect your brand and meet accessibility standards, starting with a free interactive concept.

  • Mobile App Maintenance and Ongoing Improvements

    Mobile app maintenance keeps your app working, secure and accepted by the App Store and Google Play as operating systems, devices and store rules change. Apptavio maintains the apps we build and can take over existing React Native apps after a code review.

  • React Native App Development

    React Native is an open-source framework for building iPhone and Android apps from one JavaScript or TypeScript codebase that renders native interface components. Apptavio uses React Native with Expo and TypeScript for all production apps.

  • Turn Your Website into a Mobile App

    Turning a website into a mobile app works best when the app reuses your website's content but adds things a website cannot do well, such as accounts, reminders, loyalty and fast repeat actions. Apptavio starts by building a free interactive concept from your existing site.
