### 5/5 — Great App

*2024-09-23*

Great App. Only request would be to add Feng Shui coins to the list of wishes.

### 3/5 — This app is kinda disappointing...

*2023-07-01*

So at first, I had no problems. I was messing around with the friction and speed and stuff, when I discovered that once you set the controls, you can't undo them. You have to delete the spo and reinstall it. Overall the app is pretty cool and I love the music. Please please please make it so you can mess around with the controls all the time. Maybe add a menu button on the side.

### 5/5 — We want more lol

*2022-11-11, version 2.56*

There isn’t really anything like this in the Apple Store, at least nothing that I found. I love the soothing music and just about everything about the app but I was hoping maybe you could add a few more scenes, just for a little variety as I use this app frequently

### 3/5 — Wish there’s water sound

*2021-04-16, version 2.56*

Thought there’d be water sounds but there’s not. Wish there’s a option with water sound only

### 2/5 — No water sounds

*2021-04-14, version 2.56*

So this app looks pretty good, but instead of hearing the water as you run your fingers through it there is only music.  For me a big part of the reason apps like this feel realistic is the sounds that accompany the movement of the water.  This was a big miss for me.

### 5/5 — Please, Never Remove this App

*2021-04-13, version 2.56*

When I was a kid, my sister had this on her iPod Touch and I would always use it.  I absolutely loved the music and it would help me calm down.  And it still does to this day, I would say even more so now because of COVID and just the normal stress that adults face growing up.  And I hate it when a game I played as a kid isn’t available in the App Store anymore or the app says I can’t play it anymore cause it’s not updated, it makes me so sad, but this app is so different.  Whenever I hear that woman’s voice, it brings me back to the simple, easy and fun days that I had as a child.  So please, I know this is an old app that probably not a lot of people care about, but I do.  I just pray that I can use it for as long as you allow me to.  Thank u for creating an app that stuck with me for almost 20 years.  😌👏♥️✨

### 5/5 — Original

*2020-06-29*

This app had always been a favourite since the very beginning of Iphone, there is always a space in my phone for this app, thank you!

### 5/5 — Awesome app

*2020-01-01*

I love the fluidity of the water as you touch the screen with out getting your hands wet. I have Asperger and this gem of an app helps easy the anxiety. Some fish swimming about would be even better.

### 2/5 — Coin only available in settings?

*2018-11-05, version 2.56*

You have to go into settings every time you want a coin.

### 5/5 — Special education

*2018-08-09, version 2.56*

Love this app  gave it five stars just to be nice. Perfect for us that have special needs. But one suggestion, can you add a Water sound effect when you touch the screen? I’ll be a lot of fun. Especially those that are visually impaired I’m sure they would enjoy it.
