Best for disabled Granny

I have tried numerous calculator apps, but ClevCalc is the most clever to help me (not as clever as my beloved Service Dog, but she’s the best of the best!). I have PTSD, Lupus and Fibro and, on top of that, I’m old, so I often forget how to access my own memory - ClevCalc to the rescue when it comes to money or needed conversions. Anyone can use ClevCalc without training & benefit from the helpful features - if I can easily use, most will have no trouble at all.

Thanks for a great app & even though I’m on a VERY limited budget, I use this often enough that it was worthwhile to purchase the Pro version.

Great calculator for routine calculations!!

I just switched to an IPhone & had to pick a calculator- my Moto Z had a very good one! This one, Was found on my 2nd try. I like that this one shows the numbers being added (keeps the running total), it has a backspace key to delete your last input, and displays the total while calculating!! This one is a great tool!
