The app drains battery and lags.
We profile every screen against real devices, not just simulators, so performance issues get caught before launch.

Mobile App Development Company — iOS, Android & Flutter
Apps that feel native, not bolted on.
We build cross-platform and native mobile apps with clean, hand-written code — one Flutter codebase where it fits, fully native where the platform demands it.
Sound Familiar?
The problems we get called in to fix.
If you recognise two or three of these, a rebuild will pay for itself faster than another round of patches.
It keeps getting rejected from the store.
We build to Apple and Google's actual review guidelines from day one, not as an afterthought before submission.
iOS and Android versions drift apart.
One Flutter codebase for both platforms, so a fix or feature ships everywhere at once, not twice.
It breaks the moment the signal drops.
Offline-first data handling and sync logic, so patchy connectivity degrades gracefully instead of crashing.
Every update seems to break something else.
Automated testing across the core flows before every release, so a new feature doesn't quietly break an old one.

What's Included
Every build ships with all of this.
Not an upsell list — this is the baseline on every app project we take, whatever the size.
One Flutter codebase for iOS and Android where it fits, or fully native where the platform demands it.
Cold-start time, memory, and battery use checked against real mid-range devices, not just a flagship simulator.
Notifications, background sync, and offline-first data so the app stays useful with a weak signal.
Secure auth, encrypted local storage, and sensible API handling configured before anything ships.
App-store listing assets, screenshots, and compliance review handled as part of the build, not after.
A reliable backend with an admin panel your team can use, plus app-store account handover.
Cross-platform build
One Flutter codebase for iOS and Android where it fits, or fully native where the platform demands it.
Who It's For
Built for how your users actually behave.
The platform and the architecture change depending on who's using the app and what they came to do.
01
Corporate & B2B
Internal tools and field-service apps that replace paper forms and spreadsheets with something your team actually opens.
02
Startups & SaaS
A companion mobile app for a web product, built to ship fast without duplicating the whole engineering effort.
03
Retail & D2C
Shopping apps with a fast, low-friction path from browsing to checkout, built for repeat use, not a one-off visit.
04
Education
Student and parent apps for schedules, attendance, and communication that hold up under real daily use.
05
Healthcare
Appointment and patient-facing apps built with privacy, accessibility, and offline reliability in mind.
06
Finance & Legal
Secure, compliance-conscious apps where authentication and data handling actually matter.
Scope Estimator
Rough out your timeline in ten seconds.
Pick what you're building and we'll show an honest range. It's an estimate, not a quote — but it's the same maths we start from.
01 — What are you building?
02 — Which platforms?
03 — Anything else? (optional)
How A Build Runs.
Six stages from first call to a live app — nothing advances until the stage before it is signed off.
01
Discovery
2–3 daysWe work out what the app actually has to do — who it's for, what action matters, and what can be cut for v1.
02
Architecture
3–5 daysPlatform choice, data model, and the technical approach, agreed before design starts so nothing gets rebuilt later.
03
Design
1–2 weeksHigh-fidelity screens for every key flow, reviewed with you until the direction is signed off.
04
Build
3–10 weeksFront-end and backend built in sprints, with a test build you can install on your own device at any point.
05
QA & Store Submission
1–2 weeksDevice testing, crash monitoring, and store-guideline review — then submission and release.
06
Support
OngoingPost-launch fixes, monitoring, and OS-update compatibility. You keep the code either way.

We were able to successfully complete the project by meeting the best partner. They have a very good understanding of development and skills, and are fully committed to the task schedule.
Their communication and problem-solving skills are top-notch. The entire workflow was smooth and professional.
Amazing team! Delivered everything on time with exceptional quality. Totally recommend!
Honestly, we were struggling to keep up with our growth until they stepped in. They didn't just build the tech; they actually understood our users. It's been a total game-changer for our workflow, and the design is just spot on.
What I love most is that they don't just say 'yes' to everything — they tell us what's actually going to work. The whole process felt super collaborative, and they genuinely cared about making the project a success.
Our Principles
Three commitments that govern every project.
No deadline we don't hold ourselves to.
We pad the schedule honestly upfront so we don't have to renegotiate halfway through. If we say a date, we hit it.
DeliveredNo progress you can't see.
You get an installable test build early and often, so you're never waiting a month to see what's been built.

What You Receive
Everything, at handover.
Here is the exact list of what lands in your accounts when the project closes.
01
App store accounts
Apple Developer and Google Play Console accounts registered in your name, with credentials handed over.
02
Design files
The Figma project with components and styles, so future work doesn't start from a screenshot.
03
Admin access
A login to the admin panel, so your team can manage content and users without touching code.
04
User guide & walkthrough
A plain-language guide to running it day to day, plus a live walkthrough for your team at handover.
Everything above transfers to your accounts when the project closes.

FAQ
Questions we're asked before every engagement.

Flutter covers most consumer and internal apps well and ships to both platforms from one codebase. We'll recommend fully native Swift/Java only when a feature genuinely needs it — camera-heavy or hardware-specific apps, mostly.
A focused MVP is usually 4–6 weeks. A full consumer app with accounts and push runs 8–12 weeks. Marketplace and enterprise apps depend on scope — use the estimator above for a rough range.
Yes. We prepare the listing assets, handle the review process, and submit under your own developer accounts, so you're never locked out of your own app.
For apps that need it, yes — we build offline-first data handling that syncs once the connection returns, rather than the app simply failing.
Where it makes sense, yes — we build an admin panel or CMS so your team can manage content without waiting on a new app release.
Every project includes a post-launch support window for fixes and OS-update compatibility. After that, you can keep us on a monthly retainer for updates, fixes, and support.
