Do I need a maps SDK for iOS and Android?

Maybe — it depends on what you mean by “maps” and how native your app needs to be.

You likely need an iOS and Android maps SDK if:

• You want native map rendering inside your app
• You need interactive maps like pan/zoom, markers, polygons, directions, etc.
• You want platform-specific features like location permissions, offline maps, or turn-by-turn navigation
• You’re building with native iOS/Android, or a cross-platform app that still uses native map views

Common examples:

• Google Maps SDK for iOS and Android
• Mapbox Maps SDK
• Apple Maps / MapKit on iOS
• Azure Maps, HERE, etc.

You may not need a maps SDK if:

• You only need to open a map in the browser or external app
• You can use a web-based map in a WebView or embedded iframe
• You just need static maps or simple location links
• Your app only shows an address and launches Apple Maps / Google Maps externally

If you’re using cross-platform frameworks:

• React Native / Flutter / .NET MAUI / Ionic often still use native map SDKs under the hood, or wrappers around them.
• You usually still need to choose a map provider and integrate their SDK or plugin.

Quick rule:

• In-app interactive map? Yes, you probably need a maps SDK.
• Just “view this location” or “navigate there externally”? Not necessarily.

If you want, I can recommend the best option based on your stack:

• native iOS/Android
• React Native
• Flutter
• web
• Flutter/MAUI/etc.
