Keys are too small, some are unreadable. Unable to get the simplest graph drawn. I think the developer can fix this and I hope he/she does.

A Google User

Looks very nice, and seems to work well, but I really need a graph to plot polar functions.

A Google User

Great app, but very difficult to write a function... please little more friendly user app

A Google User

wish if the buttons were bigger otherwise the app really helps in drawing funcions... thanxxx

A Google User

Can not use calc keyboard. Is tiny and unreadable.

A Google User

The calculator is not usable. The buttons are not big enough to fit the text. Deleted until it is fixed.

Conceptul este bun, aplicaţia ar putea fi foarte utilă. Cu toate acestea, butoanele sunt prea mici pentru a putea fi utilizat, cel putin pe Galaxy S.

## Luftfeuchte Rechner

Mit Hilfe des Luftfeuchte Rechners kann die zu erwartende relative Luftfeuchte bei Temperaturveränderung (Erwärmung/Abkühlung) berechnet werden.

Zu berücksichtigen ist, dass die Oberflächentemperatur an Wänden, Decken, etc. im Normalfall geringer ist als die gemessene Raumtemperatur. Daher kann es an diesen Stellen bei höherer Luftfeuchte früher zu Problemen mit Schimmelpilzbildung kommen. Ein erhöhtes Risiko für Schimmelpilzbildung besteht bereits bei einer relativen Luftfeuchte von 80%, schon deutliche vor Kondensatbildung (100%).

## Function Maker

You can use Function Maker to create your own functions/formulas and reuse them later on with ease. It supports normal mathematical operators and some of the more common mathematical functions (trigonometric, ln, exp). Any function can have up to 10 inputs and 10 outputs. Currently does not handle imaginary numbers.

* We are testing this feature at the moment. The points were calculated numerically. That's why it is possible that not all points are found, especially with non continuously differentiable functions.

Are there any open questions? Send us an E-Mail: cassiopeia.applications@gmail.com

Why does this application need the permissions:

Internetconnection: To support the development of this app, I added advertisements to the app.

Write on external storage: To export the graphs as an PNG-file we need to write on the external storage.
