Watch their journeys unfold in real time, learn their stories, and become part of the effort to protect them. The Turtle Tracker app connects you directly to sea turtles fitted with satellite transmitters by researchers and conservationists. These aren't simulations – they're real animals, tracked as they migrate between feeding grounds, traverse ocean currents, and return to nest on the beaches where they were born.

Add your favorites and check in as their tracks grow across the map. Watch migrations unfold Explore detailed route maps showing each turtle's path from release to their latest ping. See the distances they cover – sometimes thousands of miles – and the speeds they maintain across the open ocean.

Verdict
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.
