Apps people keep on their phone.

One codebase, both stores, and someone who stays after launch. We have shipped apps for an investment firm and a national payment network — the kind where a crash costs real money.

In short

We build iOS and Android apps from one codebase, so the second platform does not double the cost. That covers design, build, both store submissions and the updates after launch. Typical first version: three to four months from start to store. Your app store accounts stay in your name.

One codebase. Both stores.

what this actually means

Getting the app built is the easy part. Getting it approved, updated and kept alive is where projects die.

Most people asking for an app are really asking for three things: something their customers will actually install, something that gets through Apple and Google review without a month of back-and-forth, and someone who is still there when iOS 27 breaks a library.

We build for both platforms from one codebase, which is why the second platform does not double the cost. Your app store accounts stay in your name. When we hand over, the code is in your repository and another developer could pick it up.

Apps we have worked on run payments and investments — sectors where a bug is not a bad review, it is money. That standard is what everything else gets built to.

what we build

What we build.

01

One build, both stores

iOS and Android from a single codebase in React Native or Flutter. Native where the app genuinely needs it — heavy graphics, deep hardware access.

02

The submission, handled

Store listings, screenshots, privacy declarations, review responses. First-time rejections are normal; knowing why they happen is what saves you weeks.

03

Login people do not abandon

Phone, email, Apple, Google, biometrics. The sign-up screen is where most apps lose most users.

04

Payments that work in your market

Card, wallet, local rails, in-app purchases. We have built inside payment companies, so we know what actually clears.

05

Notifications with a reason to exist

Push that is timely and relevant. Badly used notifications are the fastest route to being uninstalled.

06

Offline that behaves

The app keeps working on a weak connection and syncs cleanly when it returns, without duplicating anything.

07

Your backend, or ours

We connect to what you already run, or build the API alongside the app so the two are designed together.

08

Updates after launch

Both platforms ship breaking changes every year. Optional monthly cover keeps the app working through them.

One codebase, or two native apps?

The question every app project starts with. For most business apps the answer is cross-platform — but not always, and here is where the line sits.

Apps we have worked on.

Investments

Mobile app for one of Pakistan's established investment firms — a sector where a bug is not a bad review, it is money.

AKD Investment
Payments

Our founder was CTO for six years, building the bill payment ecosystem used across Pakistani banking apps.

Kuickpay
National scale

Card lifecycle management for Pakistan's largest payment switch. Still in production after five years.

use cases

When an app is the right call.

01

Customers use you weekly, not yearly

An icon on the home screen is worth having when people come back often. For an annual purchase, a good mobile site is usually enough.

02

You need what a browser cannot do

Push notifications, offline use, camera, location, biometrics. If none of those matter, a website may serve you better and cost less.

03

Your team works away from a desk

Field staff, drivers, technicians, warehouse. Internal apps are often worth more than customer ones and get built far less.

04

Your competitors have one and you do not

Sometimes the honest reason. It still counts — but it should not be the only one.

approach

How we work.

01

We ask whether you need an app

Sometimes a fast mobile website does the job for a fraction of the cost and effort. We would rather tell you that early than build something that gets installed and forgotten.

02

We agree scope and dates

What is in version one, what waits, and when it reaches the stores — in writing before anything starts.

03

We design the screens first

Clickable screens you can hold on your own phone before a line of app code is written. Changing a design is cheap; changing a built app is not.

04

We build in two-week blocks

You install each build on your own device as it progresses. Not screenshots — the actual app.

05

We test on real devices

Not just the newest phone. Older Androids, smaller screens, weak connections — where most users actually are.

06

We submit and get it approved

Both stores, under your accounts. We handle rejections and resubmissions; a first rejection is routine and not a delay if you know the process.

07

We stay for the updates

Documentation and code handover, then optional monthly cover for OS updates, store policy changes and new features.

faq

Frequently asked.

7 questions answered. Still have one? Reach out.

A focused first version is usually three to four months from start to store, including review. Something with payments, several user types or an existing system to connect to is more often five to eight. Store review itself is normally one to three days now, but a rejection adds a cycle — which is why we plan for one rather than hoping to avoid it.
