Mobile App Development Company in Chennai

A single-flow MVP is ₹80K-1.5L over eight to twelve weeks. A field force app with offline sync and GPS runs ₹1.5-3L. Dealer or technician apps integrated with an ERP are ₹2-4L, because the integration usually outweighs the app itself. Healthcare and diagnostics apps sit in the same band given the data handling. Both platforms and store submission are included throughout.

Yes, and for Chennai field operations it is the requirement that matters most. The app writes locally, queues changes, and syncs when connectivity returns, with conflict resolution decided up front rather than left to chance. We also handle the awkward realities: a technician whose phone dies mid-route, a partial sync that fails halfway, and a device that has been offline for three days. Those cases decide whether field staff keep using an app or quietly stop.

Yes, and properly. Real translation reviewed by a Tamil speaker rather than machine output, correct font rendering across Android versions including older devices, and layouts tested against Tamil strings that often run considerably longer than the English. That length difference breaks buttons and labels in most bilingual apps, and it is a layout problem to solve at design time rather than a translation problem to solve at the end.

Usually, and it is planned as its own workstream because that is where these projects slip. We start read-only to understand the data properly, put a thin API layer between the app and the ERP so the app never touches it directly, and design the sync assuming the ERP will be unavailable sometimes. For dealer and technician apps around Ambattur and Oragadam this integration is typically more than half the engineering.

The ones your team actually carries, which we ask about early. For most Chennai field deployments that means mid-range Android phones two or three years old, often with limited storage and an older OS version, not a current flagship. We test on physical devices in that range because performance and storage behaviour there is genuinely different, and an app that only works well on new hardware fails in the field.

You do, from day one. The repository sits under your organisation, the Play Console and App Store Connect accounts are registered to your company, and signing keys are handed over with rotation documentation. We have inherited too many apps where a previous vendor held the keys and could not be reached, which forces a new listing and the loss of every existing install.
