/ mobile app development

Mobile apps for your customers and your team.

We build Android and iOS apps around what your customers or staff need to do. Your project can include a server, admin panel, payments, notifications and offline use. We also help prepare store submissions and plan support after launch.

Good for

  • Businesses whose customers book, order or pay again and again
  • Teams with staff in the field — sales, delivery, collections
  • Owners of an unfinished app that needs rescuing
  • Founders with a product idea who need it built and run
  • Businesses whose users are more comfortable in Marathi or Hindi

A first version of a mobile app usually takes eight to fourteen weeks, depending on scope, plus time for store testing and review.

/ sound familiar?

What usually gets in the way.

  • 01

    Staff in the field, work on paper

    Orders, collections and site visits are written down and typed in later, if at all.

  • 02

    Customers have no easy way to reach you

    Booking, ordering or paying again means a phone call, and there is no simple way to remind them about you.

  • 03

    An app that was started and never finished

    Half-built, with no admin panel, or stuck in Play Store review — and the developer has stopped replying.

  • 04

    The store side feels like a project of its own

    Listings, data-safety forms, testing rules and review rejections take time to get right.

/ what we build

What we can build for you

  • Android and iOS apps

    A shared codebase using React Native or Flutter, with platform-specific testing and releases for Android and iOS.

  • The server and admin panel

    The back end, the database, and a web admin panel where your team manages users, content, orders and reports.

  • Offline support

    Apps that keep working on a weak signal and sync when the connection returns, for staff out in the field.

  • Notifications and payments

    Push notifications, WhatsApp alerts, and in-app payments through Razorpay and UPI.

  • Apps in your users’ language

    Screens in English, Marathi, Hindi or other languages, so everyone can use the app in the language they read best.

  • Store release and updates

    Play Store and App Store listings, data-safety forms, closed testing and release, then regular updates as Android and iOS change.

/ how it runs

Step by step.

  1. 1

    Decide what the app must do

    Who uses it, what they do in it, and what belongs in the app versus the admin panel. The first version stays small on purpose.

  2. 2

    Clickable design

    You tap through the app on your own phone before we write any code.

  3. 3

    A test build every week

    A new build on your phone each week, with milestones you pay as they are delivered.

  4. 4

    Testing and store release

    Closed testing with real users, the store listing, data-safety and privacy forms, and release.

  5. 5

    Updates and support

    Fixes, new features, and the yearly changes Google and Apple ask for, so the app stays in the store.

/ questions

Mobile apps: what people ask.

Should I build for Android, iPhone, or both?

Most smartphone users in India are on Android, so many businesses start there. We build with React Native or Flutter, so adding iOS later is mostly testing and store work, not a rewrite. We will help you decide based on who your users are.

How long does it take to build an app?

A first version usually takes eight to fourteen weeks, depending on scope. Store testing and review take additional time, and requirements vary by app and developer account. We plan for those steps in your timeline.

Whose account will the app be published under?

Ideally yours. We help you create your Google Play and Apple developer accounts and publish under your business name, so the app and its users stay yours. The stores charge their own developer fees, which you pay to them directly.

What does it cost to run an app after launch?

There are server and hosting costs, store fees, and the work of keeping the app updated — Android and iOS change every year, and apps need small updates to stay in the stores. We explain these before you start, and offer a maintenance plan to cover them.

Do I get the source code?

Yes. Once the project is paid for, the code for the app, the server and the admin panel is yours.

Can you take over an app someone else started?

Often, yes. We first review the code and the server to see what state they are in, then tell you honestly whether to fix it or rebuild parts of it.
