OneCalc+ All-in-one Calculator

Disappointed, I payed for the add free version then I emailed the developers to say that I was still getting add's, even though the money was taken out of my account I was told I payed it into the wrong account even though I used the link from the app, so I won't be doing that again, would seem that the developers are just trying to rip people off!

Good calc app as it has the added scientific functionality like "to the power of" and "brackets". Better than basic calculators but not confusing like full-on scientific calc's which can be fiddly and time consuming. I calculate interest, future values and depreciations over time and this calc does the job. Im very happy as was able to purchase the ad-free version for no-nonsense usage. Hey developers... Great app! Thanks!

nov 2022: I think it was a bad idea changing the name; I can never find "One" instead of "Calc" in my app list now. been using it for a few years and it's been at the top of the list and now it's somewhere in the middle! however, easy to fix, I just change the name locally. simple and functional.
