Customer Reviews

Love this App, Except...

I've been using this app for over 4 years now. I especially like it on the iPhone 6 as the larger screen improves button accuracy. I would have given a higher ratings if the current version had the old user interface as one of its options. I loved the look of the older version (exactly like the real calculator), but don't care for the new look. I especially dislike that the option to lock it in landscape mode is gone. In the real world, having your buttons change location just because you happened to tilt a little too far is annoying and counter-productive. I'm glad the update appeared on my iPad before my phone got it, as the phone is where I really use it a least a couple of times a week. I will really try to avoid upgrading to this version as long as possible.
