Upgrades must be paid for, no longer able to see ad

It took some getting used to, but when I first got this app, I was able to unlock additional features for a day by viewing an ad. I thought this was a small price to pay. Now, you have to upgrade. However, I still rate this as a five-star app because there are so many features available even for the free version.

The one change I would like to see is a separate Memory store button instead of needing to use M+ to put something into memory. The way it works now, if I want to totally replace what's in Memory, I have to hit MC (memory clear) and then M+ - two keys/buttons, compared to one serving this function in other calculator apps I have tried and on physical calculators. Again, not serious enough to not rate this with five stars, just something that would be nice to have in a future release.


Easy to use with many features!
