Mobile App Development Company in India

There is no single figure, and any company quoting one before understanding your requirement is guessing. Cost is driven by the number of screens, whether you need Android, iOS or both, how much custom design is involved, what systems the app connects to, and whether you also need admin dashboards or backend infrastructure. A Flutter build covering both platforms usually costs less than two separate native builds. Send through your feature list and you will get a range against your actual scope rather than a generic price.

Timelines depend on scope more than anything else. A focused MVP with one core user journey moves considerably faster than a multi-role app with dashboards, payment integration and offline support. The other variable is usually on the client side: how quickly feedback comes back on designs and test builds, and how stable the requirements stay. Progbiz shares an estimated timeline with milestones at the scoping stage, and flags immediately when a scope change will move a date rather than absorbing it silently

It depends on your users. If most of your customers or field staff are on Android — the majority in India — an Android-first release gets you to market faster and cheaper. If your audience skews towards iPhone, start with iOS. If you need both and the app does not depend on deep hardware access, Flutter gives you one codebase for both platforms at close to native performance, which is the route most Progbiz app projects take. React Native is a capable framework but is not currently part of the Progbiz stack.

Yes, and the work looks different for each. Startups typically need a lean first version that proves the idea and can be shown to users or investors, built to be extended rather than rebuilt. Established companies more often need an app that fits around systems already running — an ERP, a CRM, a dealer network, a patient database — where the integration work matters as much as the app itself. Whichever you are, choosing a mobile app development company in India should come down to whether they can show you comparable work.

Ask for apps you can actually open, not screenshots. Check whether design, development and testing sit in the same team or are handed between vendors. Get the post-launch support terms in writing before you sign, not after. Confirm who owns the source code. Ask who your point of contact is and what happens when they are unavailable. Anyone comparing the best mobile app development agencies in India will find similar claims on most websites — the differences show up in the answers to those five questions.

Yes. Testing is handled by an in-house team rather than left to the developers who wrote the feature, and it runs alongside development rather than only at the end. Builds are checked on real devices across screen sizes, Android and iOS versions and varying network conditions, including the slower connections many Indian users are actually on. Functional testing, usability checks and pre-submission store compliance checks are all part of the process, and the same team handles regression testing on later releases.

Post-launch support covers bug fixes, crash monitoring, compatibility updates when Android or iOS release new versions, and resubmission when Apple or Google change their store requirements. Beyond maintenance, most apps need feature work — the things users ask for once they are actually using it. Support scope and duration are agreed in writing before the project begins, so there is no ambiguity about what is included in the build price and what is billed separately.
