Organic Maps is one of the few applications nowadays that supports 100% of features without an active Internet connection. Install Organic Maps, download maps, throw away your SIM card, and go for a weeklong trip on a single battery charge without any byte sent to the network.

Positive impressions:

• works great on iOS (didn’t test on Android yet)
• a great companion for cycling within the city
• more fun and more lightweight than Google Maps
• low impact on device battery life
• extremely privacy friendly (no ads, no tracking, no push notifications, etc)
• extremely mobile data friendly (works fully offline)
• open-source, and without any IAP
• works out-of-the-box, no sign up necessary

Negative impressions:

• do not use it for public transit, it is terrible as it does not have real-time data integration

Update(2025-12): It turns out Organic Maps is also great to track routes (e.g. during hiking or bus tours).
