1. 1/5Good app made bad! Don’t update! Don’t buy!!

   This was a good app that was intuitive and easy to use. Calculators should be quick and easy to use, as this one used to be. However, This latest “modern” update turns an easy to use app into an obtuse mess. Grey fonts on a light grey background make reading difficult. Minimized / no borders around anything make icons and functions bleed together. Hiding the tape so one can now “scroll it” instead of just looking at it when it was normally visible, is just dumb, and makes one hunt for something that just used to be there. Save yourself frustration and stay with the current version. Do NOT update like I did. Also, given the history of this developer, do NOT buy! Most likely, in a couple of years the developer will release another update that will again invalidate your previous purchases. I don’t trust companies that take away features you paid for, just so they can charge you again for an app that was previously working fine. Off to find a replacement.

2. 5/5Great Multi-function Calculator

   This is more than just your standard calculator. There are 4 modes to choose from. The one I find most useful is the Tape Mode. It is great for itemized calculations. There are just a couple of small issues that prevent me from giving it a perfect 5-star rating. The first is that while having a Scientific Mode is great, having a Scientific Mode with a graphing screen would have made any other calculator app obsolete. Secondly, there is no backspace key. This would make it so much easier to fix the most common typos. Instead, you must clear and re-enter the entry altogether. Not a huge problem, but just a bit inconvenient.

3. 5/5Just what i was looking for, works as billed

   This is one of those great apps that does exactly what it says it will and what you want it to do. The only difficulty was actually finding it. There nothing to tell one it has a tape, the feature I was looking for. I just happened on the app. But of course, like most apps that are great, you want stuff added. For example, adding a text note to the tape would be helpful, as would negative numbers on the tape appearing in red.

4. 1/5Terrible Update

   Hate the change to the interface. Lost all the original functionality that I paid for (tape, interface choice, export, printing) etc. Expect me to pay for it again? Don’t think so. Can some one please tell me how I can restore the old version? I received a response from the developer explaining that all the functionality of the prior version was still there. Functionality, maybe but usability, no. Here is my reply to the developers I used your calculator app on my iPad for many years. I liked it very much. The interface was clean and professional. I liked the “tape” function. The latest update completely changed the interface. It is now one big blob of white where you can barely tell the buttons apart. The tape is no longer conveniently beside the calculator. It must be accessed separately. I understand that the colors can be changed with the in app purchase. That’s not the point. The new interface and way the calculator/tape work is a step backwards. For me the calculator is now clunky , awkward and difficult to use. For me it’s so bad that I had to delete the update and restore the old version. Consider going back to what worked because for me this doesn’t, and I’m certainly not going to purchase the premium features since the basics are unusable for me.

5. 1/5Awful update :-(

   This was my favorite calculator. Everything I loved about it has been swept away with the latest update: the warm, simple desktop look, the handy tape that was easily visible as I worked, and the simplicity with which I could clear or print it. I also hate the unicolor design of the update. It is much harder on my eyes than the previous version, and in my opinion is just blah, plain, and ugly instead of elegant like it was before. It is also harder to use. In spite of my efforts to view the tape and toggle between the tape and the calculator keypad, I get stuck in one view or the other and find the whole thing useless. Please bring back the previous version, or offer it as an option for those of us who prefer it.
