The problem

What's holding your growth back

Two codebases, double the cost

Separate iOS and Android teams double your budget and timeline. Cross-platform done right removes that.

Apps that launch and stall

Without analytics, crash monitoring and a growth plan, most apps never get past a few hundred installs.

Scope creep sinks the budget

Undefined MVPs balloon. We scope ruthlessly so version one ships and earns.

How we solve it

Our Mobile App Development process

1

Discovery & MVP scope

Workshops to define users, core flows and success metrics; a fixed-price scope you can trust.

2

Prototype & test

Clickable Figma prototype validated with real users before engineering starts.

3

Build in sprints

Flutter or React Native front end, Node.js or Laravel backend, demos every two weeks.

4

Launch & grow

App-store submission, ASO, crash monitoring and paid install campaigns on Meta, TikTok and Google.

What's included

  • Product discovery and MVP scoping
  • UI/UX design and clickable prototypes
  • Flutter and React Native cross-platform builds
  • Node.js / Laravel backends and REST or GraphQL APIs
  • Push notifications, payments and analytics
  • App Store & Google Play submission and support

From idea to the app stores

We take mobile products from a sketch on a napkin to live listings on the App Store and Google Play. Our cross-platform approach with Flutter and React Native delivers native-quality apps for both platforms from a single codebase — cutting cost and time-to-market by up to 40%.

Our process

Discovery workshops define the MVP scope and success metrics. Designers produce a clickable prototype you can test with real users. Engineers then build in two-week sprints with demo access at every stage, backed by automated testing and a secure, scalable backend.

Beyond launch

Launching is the beginning. We provide app-store optimisation, crash monitoring, feature roadmaps and the paid user-acquisition campaigns (Meta, Google, Snapchat, TikTok) that grow installs profitably.

Frequently asked questions

How much does an app cost?

MVPs typically start from $15,000 and full-featured products from $40,000+, depending on complexity. We provide a fixed-price quote after discovery.

Flutter or React Native?

Both are excellent. We recommend based on your team's existing skills, performance needs and third-party SDK requirements.

Do you build the backend too?

Yes — APIs, databases, admin panels, authentication and cloud infrastructure are all in-house.
