Sonic Infosystem is a mobile app development company in Mumbai and Navi Mumbai that builds Android and iOS apps for businesses. We design and develop apps for customer ordering, field sales, dealer and distributor networks, bookings and service management, connected to your website and the systems you already use.
A successful app starts with a clear purpose: helping customers reorder, letting field teams log visits, giving distributors live stock and pricing, or allowing patients to book appointments. We define that purpose, the users and the data first, then build an app that is simple to use and reliable every day.
App development services
Android and iOS apps with Flutter
We build cross-platform apps with Flutter, which delivers a native look and performance on both Android and iOS from a single codebase. This reduces development time and cost and keeps future updates simple.
Business and B2B apps
Dealer ordering apps, sales force apps with visit tracking, service technician apps, inventory and warehouse apps, and customer portals for manufacturers and distributors.
Customer apps
E-commerce apps, booking and appointment apps, loyalty programmes and membership apps for retail, healthcare, hospitality and service brands.
Backend, APIs and admin dashboards
Every app comes with a secure backend and an admin dashboard to manage users, content, orders and reports, usually built in Laravel and connected to your website, CRM or ERP.
Do you need an app, or a better website?
Not every business needs an app on day one. If your customers visit once or twice a year, a fast mobile website or a WhatsApp chatbot may serve them better. An app earns its place when people use it often: distributors placing weekly orders, technicians closing service tickets, or customers rebooking. We will tell you plainly which route fits, and if an app is right, we plan a focused first version rather than a long feature list.
Our app development process
- Discovery and planning: users, features, integrations and success measures agreed and documented.
- UX and UI design: clickable prototypes so you can try the app before development starts.
- Development: built in sprints with regular test builds on your own phone.
- Testing: on real Android and iOS devices across screen sizes and network conditions.
- Launch: Google Play Store and Apple App Store listings, review and publishing handled by us.
- Support: bug fixes, OS updates and new features after launch, planned around how people actually use the app.

Working with a mobile app development company in Navi Mumbai means planning workshops and device testing sessions can happen face to face. We often combine apps with WhatsApp chatbots and business automation to give customers and teams a complete digital experience.
How much does app development cost?
App cost depends on the number of screens, user roles, integrations and backend features. A focused first version can launch quickly and grow over time. After a discovery call we provide a detailed, fixed quote and timeline.
