Very good

This app is very good, but will be a five star app If you could fix the bug that is causing the picture not to be saved because every time I close app and reopen it it resets back to the original picture.

Fix the fish!!!

I had this app long ago. It was beautiful. The fish moved gracefully, realistically. Their bodies curved if they changed direction. I could drag my finger through the water or add little chunks of food, and the fish behaved like living fish, some might approach my finger and others might be more timid, some approached the food slowly then would grab and dash away. These fish are stiff, cartoon-like, and movements are synchronized and not at all unique, adding to the fakeness. It seems nothing moves but the ends of the tails, and it doesn’t matter whether you have one fish, 2 or 20, they are all in sync: they all waggle tail tips at the same speed, same direction, same rhythm, and physically they all look pretty much the same (like copy/paste over and over). The original/old app was absolutely beautiful; this one, not so much. I encourage the developer to spend some time on the FISH, not just music or items like static flowers to stick on top or more backgrounds. It’s been years (see version history and earlier complaints) since any effort was applied to the FISH, and they are in bad need of attention, including more artistic and realistic rendering. It’s call KOI pond, but the koi are the weakest part of this app.

Dear user, thank you for your feedback. Feel free to use it. We will continue to optimize the fish's movements in future upgrades. Thank you! Look forward to it. If you have any needs, please feel free to contact us. I wish you happiness.

What happened to the older version?

This is awful. Not relaxing at all . You cannot turn sound effects off and the add ins especially the food look terrible. I miss being able to attract the koi by touching the water.

Response from developer

The sound can be turned off, but the sound of the water is preserved. The new version will turn off all the sounds at will, and the fish food will be eaten by the fish. The new version of any water surface will increase. The functions that are deleted include fish, and the water waves can be used to tease the fish. The way to fish the fish will be more and more in the future. Look forward to it! There will be a new version soon. If you have any needs, you can always contact and wish you happiness.

Not the Perfect Replacement For the Original

This app still needs a lot of work, primarily in the animation of the koi. The fish still do not have truly life-like movement. They slide more than swim. Only the very ends of the fins seem to move and this makes them look a bit cartoonish.

Still, this is the best replacement so far for the original koi pond app that so many of us know and love (but no longer works because it is was never updated to run on iOS 11).

This app is simple to use and fairly intuitive. Most of the backgrounds and sounds are well executed ... though some are head-scratchingly strange. Other more advanced koi apps require feeding to grow fish and more money to unlock more features. This app does what the original did so wonderfully and simply; present a peaceful, calm koi pond setting to relax with. Once you set the sounds and backgrounds and other visuals, you simply enjoy the fish and the mood.

However, the major drawback is very disappointing. The fish simply do not move in a realistic manner and this significantly detracts from the overall pleasure of the app.

One hopes the developer will eventually be able to address and fix this problem. But he seems far too satisfied with his latest iterations and updates.

I also wish the developer could find some better translation software, because his updates read too often like garbled word salad ... the kind of writing generated by bots that are attempting to create text for junk email selling viagra. Clearly the developer means well and wants to provide a good app, but it does seem like he’s far too satisfied with his current results.

Hopefully, the developer continues to work on this app and maybe someday he will get some help from someone who really knows how to animate the fish so that they appear life-like and move realistically.

Response from developer

Dear! I am very grateful for your suggestions, and I am very grateful for your support. I hope that more and more dear ones can know that there is such a software, it is really very good, this is the only one completely By working hard to bring you happy software, I hope that more people will know and use it and get happiness from it. I have been working hard to update, and actively interact with users to listen to user suggestions. In addition to adding other functions and more sound effects and accessories, I will make a lot of optimizations for the movements of Koi to make it more realistic. I will update it this month, look forward to it! Every update in the future will bring more powerful functions and experience. Please feel free to contact us if you have any needs.
