My favorite app!

This app has quickly become one of my all-time favorites! The fish are beautiful and mesmerizing to watch, and I love the ambient sounds of the rainfall, frogs, insects, and birds.

The ripples of the water, the shadows of the fish and plants, the occasional passing butterfly, and the distant thunder and lightning are perfect. It’s obvious to me that the developer is an avid observer of nature and aquatic life. I love the options for controlling the time of day, which directly correspond to the ambient background sounds. The underwater viewing feature is nice for when you prefer a more constant sound, rather than the changing noises of the birds and such.

This such a remarkably well-designed app, not only in the graceful and realistic movements of the fish, but also the soothing aspects. It is so thoughtful of the developer to include an ambient background function, because the app is very pleasant to use during naps or when I’m going to bed. In this way, the lights are dimmed and the power usage is decreased to enable less battery utilization.

I mostly use the app on my iPad rather than my iPhone, because I enjoy the larger viewing screen. I actually bought a better easel stand for my iPad than what I already had, just so I could better enjoy this app.

If you’re going to buy only one app for relaxation and/or meditation purposes, I highly recommend this one ❤️

As always if you have any more suggestions or feedback please get in touch either via or via, thank you again, Andy

As a goldfish/koi enthusiast, this is now my favorite app. I’ve played around with aquarium/fish apps, but this one gives me the experience of something I’ll probably never be able to afford. Enjoying a koi pond! Beautiful and relaxing, but really it’s in the koi settings where you adjust the characteristics of the koi, where I see the attention to detail. I have plenty of goldies! From lionchu, orandas, pearlscales, telescopes, and ranchu. I’m in love with kanoko patterns, and how each fish is so unique, watching how their coloring changes, black revealing orange over time. It’s interesting to see how accurate they got the color fade setting so that you can pull/fade pigments adjust color but still keep it realistic, right down to scale type! I have to drag myself away from baby koi begging for food at LFS, knowing I can’t afford a set up for them. But the app is giving me the same giddiness I get around real waterbabies.

Fish lovers app

I have always loved aquatic plants and fish, but living in a cramped city apt doesn’t provide many options. This app is stunning on both visual and audio levels. Customization of the fish colors, substrate and color of water are available, among a few other details. I like that after I select one of my fish to “follow” the menu fades away. This is a relaxing app to run when my phone is plugged in on my desk - calm and beautiful, not distracting.

Some things I’d enjoy in updates would be an option for plant customization/types choices; additional ponds with more or different above-water bird/etc sounds.. love the rain! I noticed the clouds in the sky never change even if it’s storming - it would be cool to see that improved. Really looking forward to how the developer builds things further in the future!

Thank you so much A Gerrard for your great review. I'm very hopeful you will like the next update even more, there are multiple ponds and more plant options to customize the pond with. Please contact me at or if you would like to play it before release.
Many thanks again,
