Works fine - I like that you can set your own thresholds. Note averages are based on no. of entries, not weighted by period of time between entries.
This DOES NOT measure your temperature - a reviewer below thought this turns your iPhone into a thermometer. Doesnt and doesnt claim to - you still need to measure your temperature with your own thermometer. I dont think the phone even has a heat sensor.
New version fixes the only annoyance I reported last time (that every time you entered your temperature, you had to backspace over some random number (97.88??) - fix starts it at 0 so you can enter without backspacing first. Thanks for hearing my concern and addressing it so promptly.
