Best $2 I’ve spent in ages.


First, I don’t care for fishing and have no desire to have a fish pond on my property. That said, this is a truly superb app. Found it by accident on the App Store and I’m very glad I did. The most relaxing, beautiful app I’ve had on my Macs in two decades. Graphics are great on my 27” iMac. Processor not over-taxed at all.
Being able to generate new fish and species is a wonderful touch. Very customizable - sounds, music (ambient - very good quality), water color, leaves, time of day lighting - two views - above or level with the pond. Rain if you want it. Leaves or not. And the new fish are immensely customizable. They can be named! Four of my children are swimming around in the pond as I write. I hope I remembered to feed them this morning...
I’m not able to come up with anything negative about this app. I had a feature idea which I emailed in and almost immediatley received a well-crafted response.
This may be the most relaxing and downright pleasurable app you’ll have on your Mac. Very highly recommended!

Hi rah55. Wow ... such a great review ... Thank you! I can't begin to tell you how much it means to hear from people who are enjoying it. You've given a really great summary of the app and I'm glad your processor is going well. I've been working on this for a long time in my spare time and I really wanted to make something that was as realistic as possible as well as customisable. I'd love to be able to add even more features for customisation if I can. Any more feature ideas, please let me know .. I love hearing what people would like and it really helps me to shape this app. Well I better let you back to your children ... ;-) Thanks again for the great review. :-) Andy

Better than bubble wrap therapy


Really a soothing relaxing way way to pass time. Even if you don’t want to actively play the sound effects are very relaxing and calm. incredible graphics and its obvious so much thought went into the creation of this game. I love that you can set the rain, or no rain. Set water color and plans (not to mention leaves). Forget paying all sorts of money for those nature tapes!! This has bullfrogs, thunder, ripping water and all the sweet white noise sounds you could ever want! I come on several times a day to feed my sweet babies and watching them grow and mature! I am excited to see if maybe we will someday be able to change the plants too!

I get so excited when I get a new fish to add. I also found this by accident and it is seriously the best 2 bucks I ever spent! I am super excited to see what the developers do with this.

PS~ I am running a Mac Mini so don’t be afraid! The levels of color and quality are adjustable for any Mac that meets the requirements.

Hi Tigerzivyfun - Thanks so much for the awesome feedback ... I'm glad you like it more than popping bubbles ... plus I suppose it's got the upside of no plastic to throw away at the end. ;-) I'm definitely thinking about having the option to add more plants - it would be a great addition and I'd love to add turtles and frogs as well. Thanks again for the awesome feedback. I really appreciate it. All the best. Andy.

High Quality Digital Koa Fish Pond!


remember those screensavors in the early 90’s with fish? This is a more interactive and highly impressive version!

This is Koa pond of which you can choose your fish. You start with one fish and as you progress that fishes size or attributes over time, you can earn the ability to generator or choose another fish. You also get to name that fish.

There is a variety of ways to decorate your pond with leaves, color of water, lily pads or not. the day turns to night and rain can happen anytime with or without thunderstorms.

To get more fish you have to keep your fish well fed. Once a real time day you need to feed them to keep the water clean. but over time you get to see them grow. Some fish are limited in size but some will grow to great sizes over time. The pictures are accurate though they look so much more beautiful in action. You can add new fish after your fish achieve some sizes. Each fish you can name as well.

It also comes with the ability to play some very relaxing music now and then. It is not a full piece of music but a hint of relaxation.

The sounds of the pond are clean and lovely.

You can angle your view from the top down to under the water like a fishtank view. Though you can also look up from the bottom up towards the sun or sky and all around. you can also follow a specific fish.

Very enjoyable as a digital Koa Fish tank and a casual fun of seeing them grow and adding new fish.

Hi mazyhp2346 - What a fantastic summary of what the game is and what you can do. I love that you're enjoying it. I wanted to make it like a 'Tamagotchi for fish' combined with a relaxed/mediative and zen like environment where people can just escape to. Thanks again for such a wonderful review. Andy. :-)
