Pros and cons of PCalc Lite app for iPhone and iPad

PCalc Lite app good for

As already mentioned in its name. This calculator is the anwer. It has all I was looking for. Even better - it is minding essential calculation rules and it features Reverse Polish Notation. Therefore you get five stars
I love the PCalc because of the RPN mode and I use it frequently.
If you’re looking for a calculator to replace the mundane one in iOS, look no further, because PCalc is without doubt the best in its class with literally every feature you can think about having in a calculator. From design to performance: I give it 10/10! Support from developer is very quick and precise. A must have!
I searched for a long time for a calculator that will fit my needs. This lite version is just great. As a base you get a great and fast calculator WITHOUT any ads, that will get on your nerves. Even more great, you can buy futher features you need from the full version, very cool. Now just plz add some more languages like german and this thing will become the Nr. 1 in app-store calculators. Just some thought: would be cool if the icon could change if any features are bought to the basic version; maybe a green or any other color. Just to see that it is a "powered up" version as the default lite-version.
This gets five stars from me, especially for the free version. I dont require the more advanced features and it was the nicest free calc I could find with a per cent key that didnt require a "shift". Thx
I found this program very helpfull. It is merely an upgrade of the original calculator already included in you iPod touch or iPhone. I would recomend this program in its full version.

Some bad moments

Asking 1/x for zero gives zero (no error). No configurable # digits. Just 2 stoppers, I did no go further before removing the app.
Why is there no percentage calculation... like my 15 year old casio or canon deskcalculators can do? Example: 156€ x 19% + = I can get the percentage: 156€ x 19% = but thats all. No continueous calculation
Looks fine so far, but the rules of power calculation are not implemented right: 5*4+5^2^3 is 15645 and not 390645. Not acceptable for a scientific calculator
Great calculator. I use it for many years but this new icon is inacceptable! What is that? Sentimental return to retro ios6 style? Only good for retro >60 people.
Worked very well, had all the functions nessecary for a first year chem student. Fast and simple.
It doesnt let me enter decimal exponents. When I entered 10^3.4 it gives me 1^35 which we all know equals 1. I also entered 10^2 and it gave me 1000
