Ausserdem: Warum tragen PeTA-”Aktivisten” Leder, wenn sie doch wissen, was sie damit anrichten? PeTA ist ein Geschaeftmodell.

Yes, there are and will be frequent updates. I do not get enough money from the app store to pay the bills. Therefore the updates depend on the amount of spare time.

So what you are saying is, that there should be more advanced formulas. Ok.

The graphical presentation of the list of elements was chosen on purpose as physicist normally don’t need the periodic table (at least from my experience); they need only the facts.

The app costs at the moment 99ct. This is the lowest price possible in the app store. The reason I don’t giving it away for free is, that I had to make the app in my spare time. I had to give Apple 99$ to get the app to the app store. I had to learn Objective C.
My opinion is that it is worth 99ct. This is less than a coffee to go an at least the calculator should be usable for most customers.

I still hope that the app is useful for you and that you can see my point.

Kind regards,

the physics part is ok for college or maybe undergraduated students. Most special formulas like steady or steadily accellerated movements are available.
For graduated students nearly all general formulas containing vectors, gradients or integrals like the Maxwell-equations are missing.

The mathematics part is beyond every discussion but the programm is also called phy

The chemical elements are ok even if there are missing important properties like isotope distribution, radius of the atoms, electronegativity and radioactivity, I could imagine too a better grphical presentation as this simple list.

For a free app it would be ok but from a commercial app I expect quite more.

I hope there will come frequent updates to augment the usability of the app otherwise it has been a waste of money.
