Flutter gives a London business its iPhone and Android apps, and a web app if wanted, from a single codebase: one build to pay for and one to keep current.
We write SDKs that let partners embed your service in their apps, for Flutter, React Native, iOS or Android, with documentation and sample code.
Swift apps for iPhone and iPad. We also deal with App Store Connect, including the screenshots and privacy questionnaire Apple reviews before launch.
Native Android apps in Kotlin, tested on real phones. We manage the Google Play release and the policy changes Google brings in each year.
Apple and Google ship new OS versions every year. App Care, at £675 to £1,495 a month, keeps your app current with them, fixes critical bugs and reports on its health monthly.
A senior technical lead for a few days a month: architecture, hiring and supplier choices, with honest advice when a plan won't hold up.
London businesses can get an iPhone app and an Android app from a single React Native codebase. We build with Expo on React Native's New Architecture and use EAS Update to push small fixes without waiting for app store review. If your team already knows React, it's often the quickest way to launch. Where Flutter or native would suit the project better, we'll tell you.

Foresight Mobile designs, builds and maintains iPhone and Android apps. Our London team works from the 4th Floor, Silverstream House, 45 Fitzroy Street, W1T 6EB, and our head office is in Cheadle, near Manchester. Since 2017 we've built more than 50 apps, and most builds cost £15,000 to £80,000.

New apps start with the App Gameplan: four weeks of work for a fixed £3,500, ending in a scope and a price you can take to your board.

Mobile App Development Services

Meeting our London team

You can meet the London team at Fitzroy Street by appointment; ring them on 020 4592 8294 and they'll arrange a time. Most of the work happens over a shared Slack channel and video calls, with a new test build on your phone every two weeks via TestFlight or Firebase App Distribution.

Flutter is our usual framework because one codebase covers iPhone and Android. Where an app needs native Swift or Kotlin, we'll say so in the Gameplan. More about our app development service.

London clients include Tenner, a free-to-play sports prediction game, and Schnap!, a messaging app for chatting to people nearby. We also built LPC Law's Flutter app for its advocates.

Budgets

3 to 6 weeks of development: £15,000 to £40,000. 6 to 12 weeks: £40,000 to £80,000. Larger platforms: from £80,000.

Our Mission

Built for the long run

A cheap build can turn into an expensive app to own. We use established tools and write code another developer could take over, and before you start we'll tell you what upkeep is likely to cost.

After launch, App Care runs from £675 a month. Already have an app that's failing? We'll check it for free, and if it needs a closer look, the £95 app rescue code review is credited in full when you hire us.
