### *---- "Not good"
I don't like at all. It doesn't let to change values.
-- Po777lo, 2017-01-26

### ***** "Simple and inexpensive"
This app is awesome for the price (99 cents). Works on both my iPhone and iPad and looks great. Also works for me up here in Denver where the air density is low. Great app.
-- Mechengineer1000, 2014-10-03

### ****- "Nice app"
I use this app to track mill conditions in the plant I manage. We spin cotton and polyester yarns and both temp and RH play a key role in processes running well.
