Mobile app development · since 2011

Apps people keep on their home screen.

Native iOS and Android or one cross-platform build, designed, developed, tested and launched on the App Store and Google Play by one team, with the source code handed to you.

Sound familiar?

Downloads mean nothing if the app gets deleted a week later.

Apps rarely fail on the idea. They fail on crashes, slow screens, store rejections and updates that never ship.

  • Crashes and freezes

    Bugs that only show up on certain phones turn into one-star reviews before you hear about them.

  • Slow, heavy and battery-hungry

    Long load times and an app that eats battery and data give people a reason to uninstall.

  • Two apps, two budgets

    Separate iOS and Android builds mean double the cost, double the bugs and features that never match.

  • Stuck in store review

    Missed App Store and Google Play guidelines push your launch date back again and again.

  • Installed, opened once, deleted

    Confusing onboarding and no reason to come back, so users drop off after day one.

  • A developer who vanished after launch

    No updates for new OS versions, no fixes and no one else who knows the code.

Every one of these has a fix. Here’s ours.

What you get instead

One team designs, builds and launches your app on iOS and Android, keeps it updated after launch, and hands you every line of code.

  • Native feel, either way

    Native iOS and Android or one Flutter codebase, chosen for your budget and features, not for our convenience.

  • Fast and light

    Smooth screens, quick start-up and careful use of battery and data, tested on real devices.

  • Store-ready launch

    App Store and Google Play listings, submission and review feedback, handled for you.

  • Yours, outright

    Source code, designs and documentation are handed over in full, and the app is published under your own store accounts.

What we build

Every part of your app, under one roof.

Pick the kind of app you need. Not sure if native or cross-platform is right? Tell us your goals and we’ll recommend one.

Native iOS & Android apps

Fully native apps for iPhone, iPad and Android, for products where performance and platform polish matter most.

  • iPhone and iPad apps
  • Android phone and tablet apps
  • Camera, maps and location
  • Push notifications

Cross-platform apps

One Flutter codebase for iOS and Android, so you launch on both stores with one budget and one team.

  • One codebase, two platforms
  • Native look on each OS
  • Shared business logic
  • Features released together

In-app payments & subscriptions

Subscriptions, one-off purchases and secure checkout, set up to follow App Store and Google Play billing rules.

  • In-app purchases
  • Subscription plans
  • Stripe and PayPal checkout
  • Receipts and order history

App backends & APIs

The server side your app runs on: accounts, data, notifications and connections to the systems you already use.

  • User accounts and login
  • Admin dashboard
  • Push notification service
  • CRM and payment integrations

App Store & Google Play launch

Store listings, screenshots, review submission and release management, so launch day isn’t a guessing game.

  • Store listing and screenshots
  • Submission and review fixes
  • Beta testing builds
  • Release and version management

App modernization

Fix an outdated or crash-prone app, or move it to a modern codebase, without losing your users or their data.

  • Code and UX audit
  • Crash and performance fixes
  • Support for new OS versions
  • Data-safe migration

Not sure where to start? Tell us about your app idea. We’ll recommend native or cross-platform, with a scope and a quote.

What changes after launch

Same idea. An app people actually keep using.

Drag the handle to see what changes when your app is built right.

Before

  • Crashes on some phones
  • Two codebases, double the cost
  • Stuck in store review
  • Slow screens and long loading
  • Users drop off after day one
  • No updates since launch

After launch with us

  • Tested on real iOS and Android devices
  • One team and one plan for both platforms
  • Submissions prepared to store guidelines
  • Smooth screens and quick start-up
  • Onboarding that gets them to value fast
  • Regular updates for new OS versions

How it works

From app idea to the app store, in six steps.

  1. A call about your users, features and goals, with an NDA signed first. You get a scope and a quote.

  2. User flows, wireframes and a clickable prototype of the app, approved by you before development starts.

  3. Development in short sprints, with a test build on your phone after each one so you see real progress.

  4. Manual and automated testing on real iOS and Android devices, from small phones to tablets.

  5. Store listings, submission and review handled for you, through to a live release on both stores.

  6. Monitoring, fixes, OS updates and new features, so the app keeps getting better after launch.

In their words

What clients say after launch.

I recently worked with Think Done Solutions for the development of my mobile app, and I am very happy with the results. The team was professional, responsive and delivered a high-quality product in a timely manner. I would highly recommend them  to anyone looking for a reliable and skilled software development partner.

Ask a question
ThinkDone teamStraight answers to the questions we hear most
Hi! Pick a question below and you’ll get a straight answer.
How much does it cost to build an app?

It depends on the features, the platforms and the integrations you need. For a defined scope you get a fixed quote after discovery. The estimate itself is free.

How long does it take to build an app?

It depends on the scope. After discovery you get a roadmap with clear milestones, from design through to store launch.

Native or cross-platform: which is right for us?

Cross-platform with Flutter suits most apps and keeps one codebase for both stores. Native makes sense when you need heavy device features or the best possible performance. We’ll recommend one based on your app, not our preference.

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

Yes. We prepare the listings, handle submission and fix anything the reviewers flag, under your own developer accounts.

Can you take over an existing app?

Yes. We start with a code and UX audit, fix what’s urgent, then plan updates or a rebuild if one is needed.

Who owns the code?

You do. Source code, designs and documentation are handed over in full. No lock-in.

Will you sign an NDA?

Yes, before discovery, so you can share your idea in full confidence.

What happens after launch?

We can stay on for monitoring, bug fixes, OS updates and new features, on a plan that suits you.

Your next step
