Kolkata, West Bengal · iOS / Android / Flutter
Mobile App Development for Kolkata's e-commerce & d2c brands and education & coaching businesses — designed and built by Chetan Sharma from Faridabad. Production-ready mobile applications designed for real devices, variable networks, clear journeys, and long-term ownership.
Kolkata's trading houses, retail brands, schools and restaurants are moving from word-of-mouth to online discovery.
Fixed quotes and milestone payments, priced fairly for the market rather than assuming a metro-agency budget.
The usual problem: D2C apps lose sales to checkout friction that native platforms are specifically built to remove — brands still bolt on a generic web checkout instead of native Apple Pay…

What I build: Real-time order-status sync (via websockets or polling tied to POS/KDS state) so the customer's screen reflects kitchen progress, plus location-aware ordering that…
Slot booking that stops the reception phone from being the calendar.

Mobile App Development starts at ₹1,50,000, with a typical timeline of 6–12 weeks. You get a fixed quote after a short scoping call, paid in milestones — no hourly meter.
Same timezone; the project runs async with written specs and a weekly call, same as any other Indian city.
Fixed quotes and milestone payments, priced fairly for the market rather than assuming a metro-agency budget.
A D2C skincare brand's app where cart state, wishlist, and browsing history persist across sessions and devices, checkout completes in two taps via Apple Pay, and an abandoned-cart push fires six hours after a stalled checkout. That is the shape of mobile app development work e-commerce & d2c brands businesses in Kolkata usually need.
Kolkata's trading, education and heritage-brand businesses often have strong offline reputations that their websites don't reflect yet — the fix is usually clearer structure and real photography, not more pages.
Cross-platform is efficient for shared workflows. Native is preferable when platform-specific performance dominates.
Cost depends on journeys, roles, integrations, offline behavior, backend requirements, and release scope.
