What should I use for offline maps on iOS and Android?

If you want offline maps on both iOS and Android, the best choice depends on whether you mean for personal navigation or for building an app.

For personal use

Use one of these:

• Google Maps — good general-purpose offline maps, easy to use, but offline support is limited compared with online use.
• MAPS.ME — strong offline-first experience, great for travel/hiking.
• Organic Maps — open-source, privacy-friendly, excellent for offline navigation.
• Apple Maps — improving, but offline features are still more limited and iOS-only.
• OsmAnd — powerful, highly customizable, best if you want detailed offline routing.

My recommendation

• Best overall offline app: Organic Maps
• Best for advanced features: OsmAnd
• Best for simplicity: Google Maps

For building an app

If you’re asking about an SDK/library, common choices are:

• Mapbox — strong cross-platform support, good offline capabilities, flexible styling.
• Google Maps SDK — easy and familiar, but offline capabilities are limited.
• OpenStreetMap-based solutions like MapLibre + offline tiles — good if you want more control and avoid vendor lock-in.
• HERE SDK — solid offline navigation features, more enterprise-oriented.

My recommendation for app development

• Mapbox if you want polished cross-platform maps with offline support.
• MapLibre + OSM tiles if you want open-source and more control.
• HERE if offline navigation is a top priority.

If you want, I can narrow it down based on:

1. personal use vs app development, and
2. whether you need driving navigation, hiking, or simple map viewing.
