MOBILE APP DEVELOPMENT FOR MUMBAI BUSINESSES
Working with Mumbai
We work with clients across India and abroad. Here is how a project with us runs from a distance.
APPS WE BUILD FOR MUMBAI
8 kinds of projects we take on. Tell us which one is closest to yours.
HOW A PROJECT RUNS
4 clear stages, with regular demos so you can see progress and give feedback before we move on.
Start with a free consultation
We start on video with the person who owns the problem: the restaurant owner, the society committee, the operations head at a Bhiwandi warehouse or the founder. Together we list each type of user, the one task each must complete, and where they will be when they open the app, whether on a train, in a basement car park or on a warehouse floor. You get a written scope split into launch features and later phases, so the first invoice stays small. Our guide to building an MVP explains how we trim scope.
Before coding, our designers build a Figma prototype you can tap through on a phone. Five or six real users try the main tasks over screen-share, ideally holding the phone in one hand as they would on a commute. Wherever they hesitate, the screen is redrawn. Fixing it now takes an afternoon; fixing it after launch takes a new build and another store review. This stage is led by our UI/UX design team.
Most apps use Flutter or React Native so Android and iOS share one code base, with Kotlin or Swift where a feature needs deep device access. We connect UPI and Razorpay payments, OTP login, Firebase push alerts, maps and your existing CRM or ERP. Every sprint ends with a test build installed through Firebase App Distribution or TestFlight and a short demo call. We also test what happens when the network drops mid-order, because in Mumbai it will.
Each release is checked on entry-level and mid-range Android phones and on iPhones, then submitted to Google Play and the App Store under accounts your company owns. A new personal Play account must finish a closed test first, so we plan that wait. After launch we track crashes and reviews, and help you reach first users through QR codes at your counter, society WhatsApp groups and a link on your Google Business Profile.
