## Most critical reviews (10 lowest-rated)

### 1/5 — Can’t seem to do anything

*2019-06-19*

When I launch the app, all I see is the teal blue screen with the smiley face on it. It won’t do anything. Otherwise, the app looks very helpful.

### 2/5 — No times symbol

*2016-07-09*

This app doesn't have the X like multiplication symbol. I needed that.

### 2/5 — No multiplication symbol

*2016-03-23*

I got this keyboard because I really needed a multiplication symbol, but it is not included. Otherwise, it looks nice. Unfortunately, it does not do what I need.

### 3/5 — The tiny numbers are where?

*2019-05-30*

On the App Store, the second screen shows much smaller numbers that I assumed would be superscript or subscript numbers. But on my phone it’s all large numbers, with the clunky way of using the ^ symbol to make a superscript that still is just a large size number.

**Developer response:** Hello,
To access the superscript or subscript numbers, tap and hold on the full-sized number on the first screen. You should see a pop out that shows the number with superscript and subscript options. Release your finger over whichever option you want to type. 

Thank you for your feedback and for using HappyKey!

### 3/5 — Great app. I find it very useful

*2018-04-02, version 4.0*

I know it’s not mathematical. However can you enable the power of 1 symbol. eg a^1. I’m not using this for mathematical notations and I have every number except 1. It’s there, it pops up I just cannot select it for use. Thanks

### 3/5 — Has potential

*2016-12-10*

This app has potential to be a great resource for students in school to support math recording.  However, the multiplication symbol need to be a "X" rather than a dot.  With this simple adjustment, it could be a very valuable tool for students to record math on the iPad.

### 4/5 — Where is it

*2025-12-29*

I can’t find it the letters THE LETTERS but love the app though!

### 4/5 — Where is it

*2018-03-12*

Either I can’t find it or it isn’t there but I wish there was a division symbol

**Developer response:** Hello,
The division symbol is accessible by holding down on the / key and releasing on the ÷ key. Thanks for using HappyKey!

### 5/5 — Useful

*2026-01-08, version 5.0*

Convenient, no issues

### 5/5 — Free and Great

*2024-04-11*

I was scouting the internet for hours looking for a free keyboard that uses math notation and couldn’t find any that weren’t a few dollars, a subscription service or upwards of $24!!! This app is free and works perfectly! I wish there were differentials and integral symbols but I digress this is an amazing keyboard that adds super- and subscript functionality FOR FREE! Along with a few nifty math terms! I love it!

### 5/5 — Awesome!

*2016-02-04*

Great work! Maybe I can give some input on new keys to add to the keyboard. :)

### 5/5 — This App makes my life so much better

*2015-03-23*

This app I just amazing. Every math symbol is here so I can now do all my homework on my phone. This app is the best math app there is and it makes people's life way better.
