One of the first decisions every product team faces: should we build a web app, a mobile app, or both? The wrong answer wastes 3–6 months and ₹10–20 lakhs. Here's a framework to get it right.
The Core Difference
- Web app: Runs in a browser on any device. One deployment reaches desktop, tablet, and mobile users. No app store approval needed.
- Mobile app: Installed on a device. Can access camera, GPS, push notifications, biometrics, and offline storage more deeply than a browser can.
When to Build Web First
- Your users are primarily on desktop (B2B SaaS, internal tools, admin dashboards)
- You need to iterate fast and can't wait for App Store review cycles
- Your core functionality doesn't require native device features
- You want maximum reach with minimum initial cost
- SEO and inbound traffic is part of your growth strategy
Examples: project management tools, CRMs, invoicing software, e-learning platforms, analytics dashboards. All of these are better as web apps first.
When to Build Mobile First
- Your users are primarily on mobile (B2C apps, consumer services)
- You need push notifications for engagement (food delivery, fitness, social)
- Location tracking is a core feature (logistics, navigation, local discovery)
- Camera or biometrics are required (photo editing, identity verification)
- You're targeting the Indian B2C market (95% Android, highly mobile-first)
Examples: food delivery, ride sharing, fitness apps, social apps, photo editors, on-demand services.
Cost and Timeline Comparison
| Factor | Web App | Mobile App (Flutter) |
|---|---|---|
| MVP Cost | ₹8–15L | ₹5–12L |
| Time to launch | 8–14 weeks | 8–14 weeks |
| Iteration speed | Instant deploy | 1–7 days (store review) |
| SEO potential | High (Google indexes pages) | None (app stores only) |
| User retention | Medium | High (home screen presence) |
The "Both" Answer: When to Build Together
For most B2C products, building both is eventually necessary — but you shouldn't build both simultaneously at MVP stage. The sequencing strategy that works:
- Build the web app first (faster, easier to update)
- Validate product-market fit with real users
- Use web analytics to understand which features get used
- Build the mobile app for the validated, most-used flows
This sequence means your mobile app is built with real usage data, not assumptions — and your mobile MVP is leaner and better scoped as a result.
