Android App Development That Fits How India Uses Phones
More than nine out of ten smartphones in India run Android, and most of them are not flagship devices. They are ₹8,000–₹20,000 phones with limited storage, shared data plans and networks that drop between buildings. An app that looks great on a developer's test phone but stutters on your customer's handset is an app that gets uninstalled in a week.
At Cartel Planet, we build native Android apps in Kotlin that are designed, tested and tuned for real Indian conditions. Whether you need a customer-facing app, a field-staff tool or the mobile front of a SaaS product, we plan it around your users, your numbers and your deadline, then deliver it at a fixed price you get in writing before work begins.

What Makes Our Android App Development Different
You see it before you pay for code. We build a clickable prototype first, so you can test the idea with real users and change direction while changes are still cheap.
Built for low-end phones and weak networks. We test on budget devices, keep app size lean and design offline-first, so the app keeps working in a basement shop or on a highway.
One fixed number, in writing. No hourly billing surprises. The scope, cost, timeline and what we need from you are written down before we start.
Progress you can open every week. A live staging build and a weekly demo, not monthly status emails.
You own everything. Source code, Play Console account, backend and domain are set up in your name from day one.
Our Process
Understand → Plan → Design & Prototype → Build → Test → Launch & Grow. Every stage has a clear deliverable and your sign-off before the next one begins. (Full steps below.)
Benefits
A well-built native Android app gives you a direct line to your customers: no marketplace commission, no algorithm deciding who sees you. Push notifications bring people back, saved details make repeat orders one tap, and in-app analytics show exactly where users drop off so every update is based on data, not guesswork.
Why Choose Cartel Planet
We are a development and growth team, not just a coding shop. The same people who build your app understand Play Store optimisation, performance marketing and conversion, so your launch is planned for downloads and revenue, not just for "go-live day". You get transparent pricing, a single point of contact, support on call, chat and WhatsApp, and a partner who stays after launch to help the app scale.

Our buyers in labs and industry used to call us just to check a spec. Now the full catalogue is online with exact details, and bulk enquiries come in with the right information from the start. Cartel Planet understood how a precision-parts business actually sells.
Ashwin GuptaDirector, Manufacturing company, Ambala · 26 days ago
We wanted to sell our honey, agarbattis and masalas directly and tell the hive-to-jar story behind them. Cartel Planet built a store that does both. Customers now see why our products are worth the price.
KrishanDistributor, Organic Fresh India · 1 months ago
We publish job notifications, admit cards and results all day. The portal Cartel Planet built stays fast under that volume, and our readers can filter to exactly what they need.
Himanshu GuptaOperations head [EDIT], Sarkari Job Portal · 2 months ago
We list plots, apartments, villas and commercial property across four states. Before, buyers couldn’t narrow anything down. Now they filter in seconds, and the enquiries we get are for properties that actually fit them.
Sandeep SinghManaging Director, Real Estate Industry · 3 months ago
We sell software to schools, hospitals and labs, plus hosting, training and SMS. Our old site made everyone read about everything. Cartel Planet restructured it so each visitor lands on what’s relevant to them.

FAQ
Questions about android app development
Straight answers on cost, timelines, ownership and support. Can't find yours? Ask us — a real person replies within one working day.
How much does Android app development cost in India?
Most Android apps we build fall between ₹3,00,000 and ₹15,00,000. A focused MVP sits at the lower end; apps with complex backends, multiple user roles or heavy integrations cost more. You get a fixed price in writing before we start.
How long does it take to build an Android app?
Typically 8–20 weeks. A simple MVP can launch in about 8 weeks, while feature-rich or enterprise apps take longer. Your written scope includes a milestone-by-milestone timeline.
Do you build native apps or cross-platform apps?
Both. For Android-first products where performance matters, we recommend native Kotlin. If you need Android and iOS on a tighter budget, we’ll suggest Flutter through our Mobile App Development service.
Will I own the source code?
Yes. The source code, Play Console account, backend, domain and all credentials are in your name from day one.
Do you publish the app on the Google Play Store?
Yes. We prepare the listing, screenshots, privacy policy and data safety forms, handle policy compliance and manage the release.
Will the app work on low-end phones and slow internet?
Yes. We test on budget devices and design offline-first, so key features keep working on weak networks and sync once the connection returns.
Can you integrate payments, maps and WhatsApp?
Yes. We regularly integrate UPI and payment gateways, Google Maps, SMS/OTP login, WhatsApp Business API, CRMs and ERPs.
Do I need to provide designs?
No. Our team handles UX and UI design and delivers a clickable prototype for your approval. If you already have designs, we’ll build from them.
What happens after launch?
You get 30 days of free support and a 3-month stabilisation window to fix any genuine issues real users find. After that, an optional care plan covers updates, new Android versions and new features.
Can you take over or rebuild an existing Android app?
Yes. We audit the current code, then recommend fixing, extending or rebuilding it in modern Kotlin, with a clear written quote either way.
