1. 5/5Great App as calculator apps go.

   Over the course of 5 years or so, I’ve put this app on three Samsung phones and most recently on my Apple phone. It’s worth the space it takes, very easy to read and nice to look at. I’ve paid to remove ads but the ads are small, unobtrusive and on a thin banner that runs across the bottom of the screen. I’m sure most wouldn’t object to the small ad space. I’m anal about scrolling things on my screen and gladly paid the $2.99 to make them disappear. Unfortunately there is no sign in mechanism so if you change phones, you will have to reinstall and pay again if you paid for add deletion. I would install it again and again.

2. 5/5Too many praise requests

   I’m a busy person and it bothers me when I get programmed triggered request for reviews, especially when they are repeated and numerous. Receiving your request for reviews breaks the rhythm and spontaneity of needing a quick calculation. So I’ll say this once, I like your app enough that I bought it. I actually think it’s great and would recommend it. I would like it better if you would switch the location of the C/AC key with the +/- key. I have other calculators that have the C/AC button on the right side of the calculator. I would simply find using it a more comfortable and intuitive location. I’ll give it 5 stars for now.

3. 5/5It has a back space button!

   This is a lot better than the standard app that came with the iPhone. This app has a good response when pressing the numbers and calculations buttons. I mostly use it when I want to calculate my spending and banking but most of all I like that it has a back space delete button for the mistakes I make during input. I would get so upset with the standard app that came with the phone every time I made a mistake and had to delete the entire entry and start all over. This is a good little calculator; responsive, easy to use, read and it had a back space delete button!

4. 5/5psmokerp

   This app is just what I was looking for. I like being able use backspace to change a number that I entered wrong. I also like taping on my answer and looking at the history to verify my entries. If I had a number wrong, I can tap on it and change it and continue on from that point. I can clear history at any point or I can keep it running until I’m thru. Or, I can come back at any point later and look at it again until I have cleared the history. This is great, and I don’t know if I have experienced all that this App has to offer. I have been impressed! Thank you developers!

5. 5/5Great Product

   This is a ‘go to’ product that is simple, appealing in appearance and basic enough without all the unnecessary buttons and gadgets that aren’t needed. I have this loaded on multiple devices (at minimum-5 devices) and will continue to use it for years to come. My only draw back is my own. I’m cheap so, I am annoyed by the advertising but, I find it is worth the cost, just don’t want to pay for it over and over for each device I own. It would be great if you could pay one fee and somehow it recognizes you as the owner on each of your own devices but, that’s the business. No worries for this software, safe, affordable platform.
