And the app support link is non functional. ### 5/5 — Beautiful and unique app *2017-11-16, version 1.5.9* I love the music on this, as well as all the jellyfish. Maybe the developer could put a sleep timer function on this as well as a changeable background feature, then it would be 6 stars! ### 5/5 — Good *2017-07-22, version 1.5.9* Good relaxing. Like the music included. Please keep developing jellyfish movements angles, speeds, and, music interaction. Well worth it. ### 5/5 — The only way to make it even more perfect add a sleep timer. *2017-03-26, version 1.5.9* Beautiful and relaxing. Please add a sleep timer :) ### 5/5 — Awesome *2016-05-05, version 1.5.9* It's relaxing just can't stop watching them. It's really cool. ### 5/5 — Very cool, relaxing app *2016-01-21, version 1.5.4* I love this. I was looking for some kind of aquarium app to soothe my 6 month old. I love jellyfish, so I download this one. It exceeded my expectations. The jellyfish look so realistic, it is like looking at a real aquarium. I love it. Great job. ### 5/5 — We love jellyfish *2016-01-06, version 1.5.4* My kids love this! Many times it serves as their night light until they fall asleep ### 4/5 — Lovely app but needs improvements *2015-08-30, version 1.5.4* I unlocked all three jellyfish and they are uniquely beautiful in their own way. However on the iPad Air 2, you can see some stiff lines on the edges of the jellyfish taking away the realism of the scene. The octopus jellyfish suffers most from these hard edges. Also the app crashes quite a bit. Also the inability to turn off the music so the user can add their own background music is a big oversight. Still a nice app to relax to. ## Frequently asked questions about Jellyfish Heaven HD ### What does Jellyfish Heaven HD do?
