### 2/5 — Login Broken

*2023-01-22*

Can't login on apple id and no option to login through Google. Just a spinning wheel when logging in with apple.

### 1/5 — Not working

*2023-01-21*

What is wrong with this app. I can’t log in at all????

### 2/5 — Ok app

*2023-01-19*

Could be AWESOME if it worked correctly. It will let you message people for a bit then you can’t find the messages or the person anywhere, even after restarting the app several times. Don’t waste your time.

### 4/5 — I have a reason for 4 stars

*2022-09-26*

So, this app is amazing and all but, if they made it were notifications popped up that would help out a lot like the pop up say like “Are you ready to calculate?” So it stays with the hidden theme as well as making it were we have the option to turn on the hidden feature when you talk to someone its pretty annoying that I have to click the eye every single time. 

Well thats my review and my opinion I think it would be amazing. If they added these features it would bring a whole new aspect to the app that I would absolutely love. I just hope they actually hear what I’m saying

### 5/5 — One tweak

*2022-08-12*

Love the app but would it be possible to make it so the chats aren’t automatically blurred?  As a toggle option?

### 1/5 — Help

*2022-04-20*

Trying to find the answer. Does the app send a notification if you receive a message? Or do you just have to keep looking in the app?
