Good Calc, but why costs $14.95?
This calculator/converter bundle is listed for $3.99 but when I clicked on purchase I got charged $14.95, what's up developer? I'm waiting for an answer to this...
Other than that I like this calculator and still trying to explore all the functionalities.
My 7th grade daughter can never find her calculator for math homework. She was crying that she needed one that does fractions. I tried a few, and quickly landed on the free version on this one. After months, she still likes it. I have also started using it at work. I am an engineer. I decided to buy the paid bundle because I got tired of ads. Wow. The paid version is even nicer, and I no longer have to google unit conversions (which I do several times a week at work). I am very happy. Mu daughter just texted me back after installing the paid version, and said "wow, that is fancy".
Great for the money
I previously reported a problem with being charged $17.30 for this app. It turns out that the cost of this app and another purchase from a few days before were combined and hit my inbox at the same time without details for the items, one second after buying this app. I have been using this all night, and it works great. No troubles.
