Real Aquarium HD Free 4+

This app worked just fine on my computer. No freezing or interruptions with other programs like others have complained about. The images are beautiful, although I wouldn't use this as a learning app.

The rays (Elasmobranchii) are listed under the phylum Cnidaria, which is not true. They should be listed under the phylum Chordata, along with the sharks. I haven't looked through the others to check, but at least hopefully now the designer knows and can double check the info.

Enjoy the images!

I feel like I have the vision for what this app wants to be and it's full potential. Sadly though my experience didn't even come close. I got no music, only a grey shimmery screen and every single time I tried to add a Stingray or a Jellyfish, all that happened was a faint outline of a rectangle for a few seconds. I have a 27" 2017 iMac with plenty of memory and every other screensaver of this kind I have installed runs flawlewsly . . . so I really am left to think this is just sloppy coding. I would recommend beta testing your next release before submitting it to the App store. Great idea . . . woefully executed.

I passed on this free app for a long time because of all the negative reviews, but finaly was curious enough to give it a shot and was pleasantly surprised. I've ran the app I think about four times now without even the slighest hint of problems. No bugs in this version that i've noticed. I usually just leave the app running a couple of hours while I'm cleaning up the house so although I've only had it a few days, I feel like I should of encountered some of the problems others have complained about. I'm using a late 2011 MBP running os 10.6.8. I think some people may have overlooked the requirements state you must have a system that uses a 64-bit kernel which i'm not sure was standard until the beginning of 2011. Click on about this Mac, more info, then highlight software and it will tell you whether your running in 32 or 64 bit processing.
With all that out of the way I would say RA HD is pretty good for free. It has nice looking video of Oysters, Jellyfish, Sharks, and Stingrays. It doesn't compare to blu-ray video of Blue Planet: Seas of Life or ocean footage of Planet Earth video, but decent looking footage and good length of time per species. Some of the aquatic animals are colorul and exotic looking, even the oysters, but I wish they had more exciting Seascapes. Most of the environments are grey and boring with very little plantlife. I might buy the full version while it's on sale for a dollar just to support projects like this. Don't know if I would pay full price of $10 bucks though. Tapmedia hasn't made it clear on how much more content is unlocked with purchase. There are no dolphins in this version, but I assume I would get at least a coulple more species with the nice little tid-bits of educational info to go with them.
