Too few goldfish

2025-03-22

by Theophilus C. Birdwhistle

Can you make the red one for free after we have paid for this app after all? I feel it’s boring because I can only choose white & black fish, if I want to add a bit more color to this tank I will have to pay more

Gorgeous and soothing

I’ve been waiting for this app to release while following the developer on Twitter. It’s so lifelike and soothing to just tap the water and watch these lifelike creatures swim my way.

Would love for the ability to customize colors more on the user end, but even if nothing more were ever added, this is well worth the money.

Unbelievable Quality

I’ve been following the developer on twitter for some time now and was excited to see he turned his fish sim into an app!

I’ve been looking for an app that would display a clock to put on my desk as I work, and was pleasantly surprised to see it included that function! It’s like it was made for me. I keep it on for hours as I work, and it acts a fun, soothing break when I mess with the back grounds and feed the fish.

I love the fun holiday inclusions, and have already purchased some of the Halloween fish. I hope the dev continues to add fun new content in the future.

I LOVE THIS APP THANK YOU
