# OpenLitterMap vs TrashBlitz

The clearest difference is rating: TrashBlitz at 4.4 against OpenLitterMap's 3.6. TrashBlitz also leads on ads (none vs shown) and monetization model (free vs ad-supported). OpenLitterMap's advantage is update cadence (every 3 weeks vs every 2 months) and review sentiment (83% vs 71%). On price, ratings volume, in-app purchases and device support there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.

TrashBlitz holds the better App Store score, 4.4 against 3.6. Both are backed by a comparable volume of ratings — 9 and 12 respectively. Written reviews complicate that: 83% of OpenLitterMap's written reviews are positive against 71% of TrashBlitz's, so the app with the better star average is not the one people write more warmly about.
