With Animal Tracker, you can follow the movements of wild animals all over the world that are being tracked in near-real time! These movements are collected by tiny GPS tags carried by the animals and are stored at Movebank, a free online infrastructure used by hundreds of researchers to manage, share, analyze, and archive animal movement data. You can easily participate in our scientific research projects: Upload your real-life observations and photos of our tagged animals to Animal Tracker. Your observations are crucial for our scientists! We can determine the positions of the tagged animals but we are lacking behavioral observations - we can interpret our data much better with your additional observations. Therefore: become a scientist, become an Animal Tracker!

Verdict
The clearest difference is rating: Jellywatch at 5.0 against Animal Tracker's 3.4. Jellywatch also leads on review sentiment (91% vs 54%) and iOS requirement (14.0 vs 16.0). Animal Tracker's advantage is ratings volume (28 vs 1) and update cadence (every 5 weeks vs every 3 months). On price, ads, in-app purchases and monetization model there is nothing between them.
