Short answer: the cheapest route is a WebView app for a website you already have; a full custom Flutter app falls in our custom software range of approximately ₹1,00,000 and above, depending on screens, user roles, payments and integrations. There is no honest single price for "an app" — the feature list decides it.
Three build options
| Option | Relative cost | When it fits |
|---|---|---|
| WebView app (your website as an app) | Lowest | Mobile-friendly website already exists |
| Custom Flutter app | Medium–high | Custom screens, logins, payments, Android + iOS later |
| Native Android + iOS | Highest | Heavy device features, separate teams |
What drives the price
- Number of screens and how custom they are.
- User roles — customer, staff, vendor, admin each add flows.
- Payments and wallet — gateway, refunds, ledgers, Play policy compliance.
- Real-time features — chat, voice calls, live tracking.
- Admin panel to manage content, orders and users.
- Integrations — SMS/OTP, maps, third-party APIs.
- Platforms — Android only, or Android + iOS.
Running costs after launch
- Google Play developer account (one-time registration fee).
- Server/hosting for the backend and database.
- SMS/OTP and payment gateway transaction fees.
- Updates for new Android versions and Play policy changes.
How to keep the cost down
- Launch with the smallest useful feature set (MVP).
- Reuse your website's backend where possible.
- Start on Android; add iOS when traction proves it.
- Write requirements as user stories ("As a customer I can…").
