### 5/5 — Calculator

I love this calculator. I love the big numbers because I’m legally blind and I love that it’s free my old when they wanted 599 a week I can’t afford that. This is perfect for me. I love the colors. I love everything about it. Yeah what’s up

### 5/5 — Color!

*2024-08-13, version 1.7*

This is my favorite APP! Seriously…the colors are bright, that helps me visually when I’m rushing thru a store. THEN the large size numbers help me never have to key in my numbers a second or third time! Neuropathy in fingers is setting in, so the large, bright APP is perfect!

### 2/5 — Clicking NOISE is WAY too LOUD!

*2024-08-07, version 1.7*

Enjoy the big numbers & simplicity of it.  🚨BUT that awful LOUD clicking noise it makes every time you hit a key is NUTS!!😳 WHY would they add this? Or make it so loud?  ✨This calculator could NEVER be used in a Library (esp one in College), nor on an airplane, or basically anywhere others could be disturbed.  IF there is a way to turn this sound off.. I would love to know how‼️
