Hours of Phun!

Good for hours of laughter if used correctly! I learned I fart in G shart. My son said it was the fabled brown note.
But seriously, if you have an unquenchable curiosity, you need this app.

Units?

What if we do not like meters? I gave you two stars because two years ago someone asked and you ignored this simple question/ask.

Super

Ich bin Physiker und dieses Tool ist einfach super. Ideal um unterwegs mal ein paar Messwerte aufzunehmen und sogar mit der Möglichkeit, eigene Sensoren einzubinden.
