Founders often ask whether to launch on the web, iOS, Android, or all three. The right answer follows from how your users behave, not from what feels most impressive.

Why web is often the best first step

  • One codebase reaches every device with a browser.
  • No app store review cycle, so you can ship and fix quickly.
  • Easier to share, link to, and index in search engines.
  • Lower cost to validate the idea.

When mobile should come first

  • The product depends on the camera, GPS, Bluetooth, or push notifications.
  • Users interact many times a day, in short bursts, on the move.
  • Offline use is essential.
  • Your audience is overwhelmingly mobile-only.

Cross-platform or native?

Cross-platform frameworks such as React Native and Flutter let one team ship to iOS and Android from largely shared code, which suits most business and consumer apps. Native development makes sense for graphics-heavy, performance-critical, or deeply platform-specific products.

A practical middle path

Launch a responsive web app or progressive web app to prove demand, then invest in a mobile app for the flows that benefit most. Because the API and design system are shared, the second step is faster than the first.

Let user behaviour, not preference, pick your first platform.
