BlueDen
Read full descriptionHide full description
BlueDen is a calm 3D ocean aquarium for relaxing with dolphins, whales, orcas, sharks, fish, and gentle underwater ambience. Enjoy the feeling of looking into the sea, a quiet diving window, or a small deep-sea world on your screen. Adjust the number of sea creatures, listen to soft ocean sounds, and keep a soothing underwater view nearby while you work, rest, focus, or wind down before sleep. BlueDen is made for quiet moments: a virtual ocean, a sea-life viewer, and a relaxing ambient companion rather than a game or a biological reference app.

Verdict
The clearest difference is ads: GPS Tracker at none against BlueDen's shown. GPS Tracker also leads on iOS requirement (8.0 vs 15.1). BlueDen's advantage is update cadence (weekly vs every 10 months). On price, in-app purchases and device support there is nothing between them.
