Nice But 1 Tweak Would Help

Really nice, simple interface. Does exactly what it promises to do with no distracting bells and whistles. I only wish there were a faster way to enter temperature. You have to click up or down button ten times to move each degree. A numerical entry keyboard or even a fast repeat on the up/down buttons would make this perfect.

Simple and to the point.

Does exactly what I needed without clutter or feature creep. I like it for calculating the RH required to prevent internal fogging of camera gear in hot and humid environments (using desiccant strips) or to calculate whether I'll need heating devices to prevent surface lens fogging during long exposures at night.

Dew Point

Agree with all the other reviewers -- great app!! Thanks! Will use it every day all summer I'm sure!
