### 5/5 — The best Calculator there is…

*2026-08-11, version 1.65*

The copy post feature has been a valuable time saver for me I love that option. As far as I am concerned all calculators should have that feature. If any other calculator comes along with that feature I will stay loyal to this Calculator because it has never let me down and has always been available for me to download. Congrats to the author of this app it is a keeper…..great job👍

### 5/5 — Rainbow mask

*2026-01-21, version 1.58*

I love the brightness of this calculator, and I like the different colors for the different buttons, I’m legally blind, and have other multiple disabilities, and this kind of a calculator is helpful, now if only somebody actually built a physical calculator that way then we’d really be talking.

### 5/5 — Just What I Needed

*2024-12-15, version 1.55*

After the IOS 18 update, the Apple calculator no longer showed a running total when using it, which is something I need in my business. I downloaded this app and it is perfect for what I need.  I’ve used it quite a bit and have had no issues. It’s a great calculator if, like me, you need a running total.

### 2/5 — Thang

*2024-10-31, version 1.55*

Don’t really use it much, but it’s awesome when I do.
