Since 201565+ in-house team6 cities
Android and iOS app development for D2C brands, field sales teams and booking businesses. Not every business needs an app. Build one only when it will take orders, bookings and leads.
A strategist calls you in one working day.
/ 01 Mobile app development company
An app shouldearn its place on the phone.
Most business apps are built before anyone names their job, and few people install them. PromotEdge plans and builds Android and iOS apps for Indian businesses, each with one job: repeat orders, bookings, leads or field visits.
If we can't name the job, we don't start building.
We build for corporate groups, listed companies and startups, selling B2B (to businesses), B2C (to consumers) or D2C (direct to customers online). Field apps suit industrial and real estate sales teams. Booking apps suit healthcare.
Our test: would a customer open the app once a month, and miss it if it vanished? If not, a fast mobile website or a WhatsApp flow costs less. We will say so, and point you to website design and development, or to web application development when staff and dealers will use it in a browser, or to web portal development for dealer and customer logins.

/ 02 What you get
From the first sketchto the hundredth update.
Unsure whether you need an app at all? Most businesses start with a fast mobile website or a WhatsApp flow (it needs the customer's consent; check Meta's current message charges). Send us the job and we will tell you honestly: want us to look at yours?
App UI/UX design
UX (user experience) is how easy the app is to use; UI (user interface) is how it looks. We map each flow and test a clickable prototype.
Android and iOS apps
Android reaches the budget phones Indians use. iOS suits urban or premium buyers. Apps leaning on camera, GPS or Bluetooth often need native work.
Cross-platform apps
One shared codebase for Android and iOS, using Flutter or React Native. It usually cuts build time and keeps both in step.
Admin panel and integrations
The back end your staff use, often built as a web application, plus APIs (connectors that let systems swap data) to your CRM, analytics, payments and SMS.
Testing on real phones
Every flow tested on real Android phones and iPhones, on slow networks and offline, before anything reaches the stores.
Store submission
Listings, screenshots, privacy details and review notes for Google Play and the App Store. We stay until the app is approved.
Maintenance and growth
Bug fixes, system updates, crash monitoring and new features, plus ASO (app store optimisation) so people find the app.
Our beliefWe're professionals. We'd rather be blunt than pleasing.
/ 03 Common hurdles
What usually gets in the wayand the way through.
“Lakhs spent, and few people installed the app.”
An app needs a reason to install and a plan to be found. We agree both before the build and plan the launch push with your marketing.
“People install it once, then delete it.”
Usually the app asks too much too soon, or does nothing a website couldn't. We design the first visit around one quick win: an order, a booking, a logged visit.
“The code and store logins sit with the old developer.”
Store accounts, code and server logins should be in your company's name from day one. We set them up that way and list each in a handover document.
“The Android app works, but the iPhone version lags.”
Two separate builds drift apart. Where the app allows it, we build once for both systems, so features ship together.
“Apple's review asked for changes.”
This usually means missing privacy details, a broken reviewer login or a feature that breaks store rules. We check the guidelines before submitting and fix what the reviewer flags.
“Orders from the app don't reach billing or stock.”
We map every place the app sends or fetches data before design starts: your ERP (software that runs stock and accounts), CRM, payment gateway and delivery partner.
“The sales team still fills paper forms after each visit.”
A field app with offline mode logs the visit, order and photo where there is no signal, and sends everything once the phone is back online.
“Most orders come through one marketplace or dealer, who keep the customer's details.”
An app pays off when your own customers will reorder on it. Where they will, we build the reorder path and a CRM (software that keeps every customer), so the relationship is yours.

/ 04 How we work
From ideato the app stores, and after.
As planning guidance, a focused first version takes about three to five months from first call to store launch. Want a timeline for your idea?
- 01
Discovery
Calls with sales, operations and service. We agree the job, the users, the first version and how success is counted. Usually one to two weeks.
- 02
Flows and prototype
User flows, rough screen layouts and a clickable prototype, tested with a few real users before any code. Usually two to four weeks.
- 03
Design and technical plan
Final screens for both phone systems, plus the data plan: what the app collects, why, where it is stored and who sees it.
- 04
Build in short cycles
Two-week rounds, with a test build on your own phone after each. We can't do magic alone: faster feedback means a faster app. Usually two to four months.
- 05
Test and fix
Real phones, slow networks, no network, payment failures and wrong OTPs (one-time passwords). Then a closed test with your staff or friendly customers.
- 06
Store launch
Listings, screenshots, privacy forms and review notes for both stores. Allow time for review, and for Google's 14-day closed test on a new personal account.
- 07
Measure, run and improve
We agree one number the app must move. A monthly report shows installs, users after 30 days, orders, bookings or leads, and crashes. No published case of ours is an app project, so we show no app results here.
Tell us what’s not working. We’ll send you an honest one-page growth plan, free.

How we deliver it, and why
- Name the job before any design. An app with no clear job gets installed once and deleted. The job also tells us if an app is the right tool. A one-page business case and an honest yes or no.
- Test a clickable prototype with real users. Changing a drawing costs hours, built code weeks. A prototype on your phone.
- Plan the data and the stores early. Privacy forms, account deletion and reviewer logins are what most often delay approval. A data plan and a store checklist.
- Test on the phones your buyers really use. Budget Android phones and slow data break apps that look fine on a new iPhone in the office. A test log with fixes.
- Watch use after 30 days. Installs flatter you. People still using the app a month later show the job is being done. A monthly report you can check.

Market
India saw 25.5 billion app downloads in 2025, up from 24.6 billion in 2024, and time spent in apps rose from 1.13 to 1.23 trillion hours. People use apps a lot, so yours needs a reason to stay on the phone.

Zepto
Aadit Palicha and Kaivalya Vohra first built KiranaKart, a grocery delivery app working with kirana stores. It closed in March 2021 for lack of market fit. They founded Zepto in April 2021 around 10-minute delivery from small warehouses. A first app that missed showed them what to build next.

Chaayos
Chaayos, the tea cafe chain founded in 2012, had 68 cafes in Delhi NCR, Chandigarh and Mumbai when it opened in Bengaluru. Facial-recognition login lets regulars repeat orders without OTPs, cutting two minutes to 20 seconds.

How your business model changes the plan
A D2C brand builds the reorder path and loyalty first. A dealer-led business starts with dealer ordering and offline field logs. A clinic or institute starts with bookings. See D2C and ecommerce and education.
Who sets the rules and who shaped the field in India
IAMAI, the Internet and Mobile Association of India, is a not-for-profit body of about 540 members working on policy, research and consumer trust in the digital economy. ASCI, formed in 1985, runs advertising self-regulation, so your app's ads follow its code.

AI in app development: today and next
Android's own page says Gemini in Android Studio can plan multi-step changes, suggest edits, make Compose previews, analyse crash reports and help with UI tests. We use tools like this for routine code; people review every line and decide what the app does. The free plan has usage limits.

Where this works best.
01
Construction equipment
Contractors trust the machine their peers run on site more than any brochure.
02Building materials
The person who pays for the cement is rarely the one who picks the brand.
03Industrial & manufacturing
Procurement checks you out long before your sales team is invited to talk.
04Automotive
A buyer's interest fades fast when the enquiry reaches the right showroom late.
05Real estate
Enquiries are easy to buy, but the sale is won or lost at the site visit.
06FMCG
Your ad works for a rival if your product is missing from the shelf.

No pressure. No sales pitch.
Tell us the job the app must do.We'll show you the plan.
Straight answers.
-
It depends on the screens, user types, platforms and integrations; a simple booking app and a delivery app with live tracking are different jobs. We quote against a written scope. Google Play charges US$25 once, and Apple's membership is US$99 a year.
-
As planning guidance, a focused first version takes about three to five months from first call to store launch. Discovery and design take about a month, build two to four months, then testing and store review. More integrations add time.
-
Look at your own buyers. Your website analytics show which phones your visitors use. Many Indian consumer apps need Android from day one, and urban, premium buyers may need iOS too. A cross-platform build often launches both for little extra cost.
-
We won't claim to be the best; nobody honestly can. Ask every company four things. Have they shipped an app like yours? Who owns the code? Who does the weekly work? Do they report orders, not just downloads? Ask us the same four.
-
Yes, wherever you are. We plan, manage and deliver the project, with one point of contact from scope to launch. Our in-house team of 65+ people does the work, with consultants and partner agencies where a job needs them. Our servicing team is based in cities across India, and we meet you at least once every three months.
-
No published case study of ours is an app project, so we show no app results on this page. We share relevant work in the first conversation, and you can ask how its results were counted. Ask any company the same, including us.
-
You should. The Google Play and Apple developer accounts, the code, the design files and the servers should be in your company's name. Any company should agree to that in writing, including us. If one won't, ask why, and put it in the contract.
-
General guidance, not legal advice: the DPDP Act, 2023 covers personal data your app collects, and its Rules, notified in November 2025, phase in over 18 months. Apple wants a privacy policy link in the listing and the app. Both stores need in-app account deletion. New personal Google Play accounts run a 12-tester closed test for 14 days.
