Tempdrop measures your temperature while you sleep. No alarm. No invalid readings.

Tempdrop measures your temperature while you sleep. No alarm. No invalid readings.

Your schedule isn't the problem. The method is.
You rotate between days and nights. Oral BBT requires the exact same wake time every morning — a time that doesn't exist in your life.
Your toddler had you up at 4am. Now your chart is full of open circles instead of data you can actually trust.
Every time zone change throws your chart off. You spend the rest of the cycle second-guessing every reading.
