Tempdrop's optional premium app subscription offers additional insights and data interpretation.
Fertility window insights
See real-time fertile window estimates and verification. Tap on the green window in the cycle wheel to see your estimate or interpretation for any cycle day. In chart view, find the fertile window under the chart labeled(F).
Temperature data interpretation
Temperatures jump and remain in a sustained higher range after ovulation occurs*. Our premium option will automatically detect a valid shift and interpret your results for you.
Cervical mucus interpretation
In the lead-up to ovulation, cervical mucus generally increases in quantity, and the quality changes to a more fertile type. After ovulation, it abruptly changes back to a non-fertile quality. The last day of observing fertile type mucus before this abrupt change is known as "Peak day". Identifying peak day and then adding a count of 3 days in which there is no return of fertile type mucus assists in identifying ovulation and closing the fertile window. Automatic detection of peak day and adding the count is a premium feature.
Ovulation day indication
An ovulation day indication dot is visible on both the home screen cycle wheel and chart. Until ovulation is verified by symptoms (temperature shift and/or peak day) the ovulation indication is estimated by your unique cycle history. When subscribed to premium, this ovulation indication dot will be adjusted to the day before the temperature shift once it's verified. This can be used as a guide for approximate ovulation.
- Premium subscription is optional
- Every Tempdrop purchase includes 3 months of free Premium use.
* An upward temperature shift can be influenced by other factors outside of ovulation. Cross-checking a temperature rise against other fertility signs is always recommended when making fertility decisions. Results can vary depending on individual circumstances.
