Pros and cons of ▸ Calculator + app for iPhone and iPad

▸ Calculator + app good for

Amazing software, easy to use, full featured. 5 deserved stars. Hurry and grab your copy while its free!
It would be better if the dual-line display updates live as we type. This way we could keep track of the input and results at the same time.
Hello dear creator of the app. Id like to you create a system of translation and language to support more languages, such as Portuguese, since Im Brazilian.
I am thoroughly impressed, good layout, very comprehensive, all the functions I need, thanks!!
I started to use it like5years ago on wm phone was paid app.now its more beautiful and free.all the functions you need all there.
This "THING" is awesome and has some real thought behind it. I cant call it a calc because it is so much more

Some bad moments

I just bought it and went into the settings and then could not get out of the settings, where did you get your prizes ??
The stored natural constants are useless because their base-10 exponent is interpreted as a base-e (2.7...) exponent by the calculator. Therefore, all calculations using these constants are wrong. Correct this bug and youll get 4 or even 5 stars.
App freezes under iOS 10. Not usable anymore. No updates since years, please remove from App Store
1GB = 1000 MB hummm??? How can I trust this app with mistake like that
Wrong conversion on the gig to meg.. how can I trust anything else on that calc :( Very sad cuz the concept of this calc is really great lots of diff unit everything you would ever need to count something... But come on.. On a app like this, only one mistake is unforgettable...
Dont know when they changed the App. Used have 12 functions with period table, financial calculations, biorhythm, but could NOT restore after upgrade to this version
