Wa Kingyo - Poisson Rouge 4+

There are lots of apps out there to use when you’re feeling anxious or stressed but for me they all have too many features, options, or game-like mechanics to even attempt to look through when I’m having a panic attack. I’ve been using this simple app for 11 years and it always helps ground me. The design is easy to use, and the simple mechanics mean I can just watch the beautiful art of the fish swim and the gentle sound of the water, interacting occasionally if I feel up to it. These fish have gotten me through some of my most difficult moments, and I highly recommend it for anyone looking for a quick way to destress and take a moment to ground yourself!

I love aquariums - I always appreciate doctor’s offices with live fish and go out of my way to be near koi ponds and fountains. I’ve read that being near moving fish has a soothing affect on the nervous system and I certainly can attest to this.
There are other fish / koi apps but they seem to have more of either a game aspect or gimmicky cute aspect.
This app is serene, low-frills, and perfect for the meditative effect I was looking for. I like to turn it on and lay the phone nearby when reading or doing repetitive activities.
The backgrounds are elegant and the flowers flow and ripple naturally with the water.
My only developer request is that the fish motion AI be improved slightly- it would be delightful for the fish to dart away when startled.

I love Wa Kingyo! It is simple and elegant, yet fascinating and beautiful. This app is great when you need a break from the world for a "Zen" moment of tranquility and relaxing contemplation.

The lovely graphics, realistic fish motion and stunning water effects with gentle sound make this an all-time favorite app. I have had this app for several years (since iPhone 4), and it looks fantastic on iPhone 6 Plus and iPad Air. Thanks to the developer for the iOS 8 update. Domo arigato gozaimasu, Hakozaki-san.
