# STC Turtle Tracker vs The Shark Trust

The clearest difference is in-app purchases: The Shark Trust at none against STC Turtle Tracker's 2. The Shark Trust also leads on update cadence (every 2 weeks vs every 2 months) and rating (5.0 vs 4.7). STC Turtle Tracker's advantage is review sentiment (88% vs 67%) and ratings volume (42 vs 5). On price, ads, device support and iOS requirement there is nothing between them.

Both are free to download. STC Turtle Tracker sells 2 in-app purchases, starting at $2.99 per month. The Shark Trust asks for nothing beyond the download.

The Shark Trust holds the better App Store score, 5.0 against 4.7. That said, the two scores are not equally well evidenced: STC Turtle Tracker has 42 ratings behind it against 5, so its average is the more settled of the two. Written reviews complicate that: 88% of STC Turtle Tracker's written reviews are positive against 67% of The Shark Trust's, so the app with the better star average is not the one people write more warmly about.

STC Turtle Tracker ships an update every 2 months, The Shark Trust every 2 weeks. The most recent releases landed on October 12, 2026 and October 2, 2026 respectively.
