Khattak Solutions Infrastructure
Mobile App Development
Applications people keep on the first screen — because they're fast, reliable and solve a real job.
Is this you?
- Customers are asking for something the website cannot do.
- Your field or warehouse team is working off paper or WhatsApp.
- You need push notifications, offline use, or a device camera or scanner.
- You have a web product and the next version has to live on a phone.
If more than one of those is true, the problem is usually the system around the work rather than the people doing it.
What we build
Customer apps, field-operations apps and internal tools for iOS and Android. We build on Flutter or React Native when one codebase serves both platforms well, and go native when the app depends on platform capability you can’t fake.
Beyond the app
The app is the visible part. Underneath sits an API, a database, authentication, push infrastructure and a release pipeline. We build those as first-class parts of the project, so version two doesn’t require starting again.
Decide this before you decide anything else
Most businesses that ask for an app need one of three different things, and they cost very different amounts. A progressive web app — installable, offline-capable, no store review — covers a surprising share of internal tools and customer portals. A cross-platform native app covers almost everything else. A fully native build per platform is for apps that live or die on device performance.
We will tell you which one your case is, including when the answer is that you do not need an app at all.
What we build
- Customer apps — accounts, ordering, booking, tracking, support
- Field and operations apps — jobs, inspections, stock, proof of delivery
- Companion apps to an existing platform or CRM
- Progressive web apps where store distribution is not required
- Offline-first apps for sites with unreliable connectivity
Store submission is part of the job
Apple and Google both reject first submissions for reasons that have nothing to do with code — privacy labels, account deletion routes, screenshot sets, age ratings, permission justifications. We prepare the submission, handle review correspondence and get it through, and we set up the release pipeline so your second version does not repeat the first version’s learning curve.
Backends and data
An app is a window onto a system. Where that system does not exist yet we build it — API, database, authentication, admin — so the app and the web product share one source of truth instead of drifting into two.
How the work runs
01 — Platform decision
Native, cross-platform or PWA, argued from your actual requirements and budget rather than preference.
02 — Flows
The screens that matter, mapped as a clickable prototype before a line of app code is written.
03 — Build
Two-week increments on a device you can hold, via TestFlight and internal testing tracks.
04 — Hardening
Real devices, poor networks, interrupted sessions, permission refusals, OS version spread.
05 — Submission
Store listings, privacy declarations, review correspondence, release.
06 — Iteration
Crash and usage monitoring, then the next version on an agreed cadence.
What it costs
App cost tracks the number of distinct screens and whether a backend has to be built alongside. An app onto an existing, well-documented API is a fraction of the cost of one where the API is part of the scope.
What moves the number
- Platform choice — PWA, cross-platform, or native per platform
- Whether a backend and admin already exist
- Offline behaviour and sync, which is the single most expensive requirement
- Payments, identity verification, or regulated data
- Device features — camera, scanning, location, Bluetooth
- Ongoing OS compatibility, which is a yearly cost, not a one-off
Every proposal is a fixed price against a written scope. We do not quote by the hour for work we have specified.

Common questions
Native or cross-platform?
Cross-platform when the feature set is shared and speed to market matters. Native when performance, hardware access or platform-specific interaction is central. We recommend one and explain the trade-off.
Do you handle store submission?
Yes, including store listings, review responses and staged rollout.
Can it connect to our existing systems?
That is usually the point. We integrate with CRM, ERP, payment and internal databases through a documented API layer.
iOS and Android at once, or one first?
Cross-platform gets both from one codebase and is the right answer for most business apps. Launching one platform first only makes sense when your users are genuinely concentrated on one — field teams on company-issued Android, for instance.
Do we need an app or a mobile website?
If it does not need offline use, push notifications, or a device feature, a fast mobile site or a progressive web app will reach more people for less money and nothing stands between you and your users. We say so when that is the case.
What does it cost to keep an app alive?
Budget for two OS releases a year, store policy changes, and certificate and account renewals, even in a year where you change nothing. An app left untouched for two years usually needs real work before it will build again.
Can you take over an app someone else built?
Often. We review the codebase and tell you honestly whether it is worth continuing or whether the remaining lifespan makes a rebuild cheaper.
