Mobile App Development in Kolkata FAQs

Clear answers about building iOS, Android, and Flutter mobile apps for your Kolkata business or startup.

Yes, definitely. We build mobile apps for startups, retail shops, clinics, schools, and companies in Kolkata. Everything is managed online with weekly progress updates and test builds sent directly to your phone so you can try features as we build them.

Yes. Most of the time we use Flutter, which lets us build one app that works smoothly on both Android and iOS without doubling your costs. If your project specifically needs native code, we can build separately for each.

Yes, 100%. We handle the entire submission process for both Google Play and the Apple App Store, including screenshots, privacy compliance, and store descriptions, so it doesn't get rejected over small technical details.

Yes, we integrate UPI, Razorpay, PhonePe, Paytm, and any other payment gateways you need so your customers in Kolkata can pay smoothly without friction.

It really depends on what the app needs to do. A straightforward app costs much less than one with payments, real-time tracking, or complex user roles. We'll give you a clear, itemized quote after a quick chat about your idea.

We don't just hand it over and disappear. We include post-launch support and offer maintenance plans to handle new Android/iOS updates, bug fixes, and security patches.
