Mobile app development in Navsari & Surat.
Cross-platform apps for Android and iOS from one codebase, on the same tested backend patterns I use for production web systems.
Fixed quote after a free 30-minute scoping call. Store submission included.
Agreed as a date in writing before anything starts.
One codebase, both stores
I build in React Native, which means Android and iOS come out of a single codebase rather than two separate builds. For almost every business app — a booking tool, a delivery tracker, a customer account app, an internal tool for your field staff — that is the correct trade-off. You pay for one app and ship to both stores.
Where it is not the correct trade-off, I will tell you. If your app depends on heavy device-specific hardware, real-time video processing, or platform features that only exist natively, cross-platform will fight you and you should hire a native developer. That is a short conversation, not a three-week discovery.
What I can and cannot show you
My shipped app work is covered by client confidentiality, so it is not listed on this site and I will not name it on a first call. That is the normal arrangement for contract work, and you would want the same protection on yours.
What I can show you is the layer underneath, which is the part that actually decides whether an app succeeds — and all of it is public, inspectable and linked below.
The part that actually decides whether an app works
Most apps that fail do not fail at the screens. They fail at the backend — the API is slow, the data model was wrong, the auth leaks, there is no way to see what went wrong in production. That is the part I have the most production experience in.
On CGPE Connect I built exactly this layer: an Express and MongoDB backend with JWT authentication and role-based access on every route, rate limiting, input sanitisation, structured logging, realtime updates over Socket.io, and file storage on S3 behind signed URLs. An app is a client on top of a system like that. Getting the system right is most of the job.
How the work runs
The same way as the web work: a written specification first, with every screen and every state described — including the loading state, the empty state and what the user sees when the network drops, because those are where apps feel cheap.
You get builds on your own phone throughout, not screenshots. Testing an app on a real device on real mobile data is the only way to know it is any good, and it catches the problems that never appear in a simulator.
I handle the Play Store and App Store submission, the store listings, the privacy declarations and the review process. First-time submissions get rejected for predictable reasons; knowing them in advance is worth a fortnight.
Cost, timeline and honesty about scope
Apps start at ₹30,000 and realistically sit above that, because an app is a backend, two store listings and a review process as well as a set of screens. Two to eight weeks to a first release, depending on scope, and roughly one of those weeks is store review, which is outside anyone's control.
If your idea is really a website that people would open on a phone, say a menu, a catalogue or a booking form, then a fast mobile web app is cheaper, ships sooner, needs no store approval and updates instantly. I will point that out rather than sell you an app you do not need.

Questions
Asked and answered.
If yours is not here, ask it on the call. I reply within 24 hours.
How much does a mobile app cost?
+
Apps start at ₹30,000 and most sit meaningfully above it. The price is driven by the backend and the number of distinct screens with their own logic, not by the platforms — because one React Native codebase covers both Android and iOS, you are not paying twice.
How long until it is in the store?
+
Two to eight weeks for a first release, depending on how many screens have their own logic. Roughly one of those weeks is Google and Apple's review, which nobody can speed up. Updates after launch are much faster — usually days.
Do I need an app, or would a website do?
+
If people will use it occasionally and you mainly need to be found, a fast mobile website is cheaper, ships sooner, needs no store approval and updates instantly. An app earns its cost when you need push notifications, offline use, device hardware, or a customer who opens it every week. I will tell you which one you are.
Android and iOS both, or one first?
+
Both, from one codebase — that is the whole reason for React Native. Shipping one platform first only makes sense if you are validating an idea and want to spend less, and in that case Android first is usually right in India.
Can I see an app you have built?
+
Not on this page — my shipped app work is under client confidentiality and I do not publish clients' products without permission. I can talk through the architecture, the decisions and the problems on a call, and the backend and performance work linked below is public and inspectable. You get the same confidentiality on your project.
Who owns the developer accounts?
+
You do, and this matters more than people realise. The Play Console and Apple Developer accounts must be registered to you, not to me. If a developer offers to publish under their own account, that is a lock-in you will regret.
What happens after launch?
+
Thirty days of fixes for anything that does not match the spec are included. Beyond that I can work on a monthly retainer for updates and OS-version maintenance, or hand the codebase to your team with documentation. Both are fine; neither is compulsory.
