Why are my previous temperature readings changing?

Retroactive updates to previous temperature results are normal and part of the way Tempdrop works to give you usable, accurate readings. Our algorithm is filtering variables that might have affected your initial temp result. 

This smart technology means Tempdrop will be able to filter out variables such as occasional nights of drinking or those nights of disturbed sleep giving you clear, smoother cycle charts. Because of our unique approach to measuring your true sleep temperature, Tempdrop works wonders for all women but especially for shift workers, breastfeeding moms, as well as those with irregular cycles due to PCOS and other causes.
