Native iOS, Android and cross-platform apps — from MVP to enterprise. We design, build, test and launch apps that perform, for clients in the USA, UK, UAE, India and worldwide.
The first big decision in any app project. Switch between the options to see how the code is structured and how each approach scores.
One team and one codebase ship to both stores at the same time.
Dart — one codebase with its own rendering engine
Scores are our general guidance on a 1–5 scale, not benchmarks. The right choice depends on your app — we recommend one after discovery.
Pick your platforms and tap the features you need. Watch the app take shape and see an indicative scope and timeline.
1 · Platforms
2 · Features
Indicative planning model only, not a quote: a base of about 7 weeks for discovery, design and the core app, plus 1–3 weeks per feature, and about 20% more to cover both platforms.
The screen is only the top layer. A reliable app is seven layers working together — and we build all of them.
Screens, navigation, gestures and animation — what your users actually touch.
UI/UX design →Business rules, state and local storage that make the app respond instantly.
Camera, GPS, biometrics, Bluetooth and push notifications.
Payments, maps, messaging, and your ERP or CRM connected securely.
API & integration →User accounts, data, business logic and the admin panel behind the app.
Custom software →Hosting, automated releases and scaling as downloads grow.
Cloud & DevOps →Usage funnels, crash reports and performance tracking after launch.
Analytics →Scroll through the six stages and watch the app on the right evolve from user stories to a live store release.
User stories, feature scope and platform decisions — before any design.
Wireframes and an interactive prototype you can tap through, validated with users first.
Two-week sprints, real-device testing and regular builds you can install and try.
Automated and manual QA across devices, then a TestFlight / Google Play beta with real users.
Listing, screenshots, privacy details and review management for the App Store and Google Play.
Go-live, store optimisation and close monitoring — then updates driven by real usage.
Great apps are opened again and again. Here's how five features turn into five reasons to come back — follow the sun.
A well-timed push notification brings users back at the right moment.
Push notificationsSaved cards plus Face ID or fingerprint make paying take seconds.
Biometric paymentsOffline mode keeps the app usable underground and syncs later.
Offline syncReal-time maps and status updates cut “where is it?” calls.
Real-time & mapsTimely review prompts and referrals turn happy users into promoters.
Ratings & referralsFrom a first MVP to enterprise-scale apps, across industries.
No surprises. Every project covers design, build, testing and launch — with UX/UI design up front and secure development practices throughout.
The best apps keep improving. After release we watch crashes, reviews and usage data, then ship regular updates — and keep your app compatible with each year's new iOS and Android versions.
Grow downloads with our marketing team, too.
Released on the App Store and Google Play, monitored closely for the first 30 days.
Crash fixes and quick wins from early reviews and user feedback.
Roadmap items prioritised by real usage data, not guesses.
Tested and updated for each year’s new iOS and Android versions and devices.
