# Marine Debris Tracker vs Chptr

The clearest difference is review sentiment: Chptr at 100% against Marine Debris Tracker's 39%. Chptr also leads on update cadence (every 2 weeks vs every 2 months) and ratings volume (42 vs 1). Marine Debris Tracker's advantage is rating (5.0 vs 4.5) and monetization model (free vs ad-supported). On price, ads, in-app purchases and device support there is nothing between them.

Marine Debris Tracker holds the better App Store score, 5.0 against 4.5. That said, the two scores are not equally well evidenced: Chptr has 42 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 39% of Marine Debris Tracker's written reviews are positive against 100% of Chptr's, so the app with the better star average is not the one people write more warmly about.
