やさしくタッチ！めだかヌダカ

This beautifully designed app features 18 customizable backgrounds that include their own visual effects such as rain falling and scattering the wobbling the surface of the water, fireworks in the night, and even the deep dark blue abyss with a whale shark swimming below! A group of stingrays will occasionally swim by and a terrifying giant squid will randomly pop up and block the entire screen! I have subtracted a star because there is no way to disable this and it really is quite startling every time time it happens! You can even use one of your own photos as a background! The three fish can be turned different colors by tapping on them and they can be fed and interacted with by dragging one's finger across the water. The swimming motion of the fish is very realistic and like real fish, they will scatter desperately away from any source of disturbance. The sound effects that the water makes throughout the experience is also realistic. Some final features worth mentioning that set this app apart from other similar apps is that the fish can be optionally toggled to flash and you can optionally draw in the water where a darkened imprint will be left in the background.
