How Femometer works
Why we use basal body temperature charting
Basal Body Temperature (BBT) charting has long been used to help track menstrual health, fertility, and ovulation. The idea is to catch your temperature at its lowest, or base. You have to do this before you sit up, move around or even before you go for a quick morning wee! Your base temperature will usually have a pattern that it follows throughout the menstrual cycle, a pattern that will help you spot your fertile window, ovulation and possibly the onset of your menstrual cycle too.
BBT charting to help with conception
To increase your chances of getting pregnant, it's best to pinpoint your fertile window and make sure you have sex during this time. This helps to ensure that the sperm is ready and waiting for the egg when it’s released. Within 3 cycles we are able to help you pinpoint the start of your fertile window and ovulation.
BBT charting for contraception
You can use BBT charting as part of your natural birth control plan. If you know when your fertile window is, you can use protection or abstain from sex during this time. Once you've moved out of your fertile window we will give you the all clear and let you know you're in your 'safe zone'.

When charting BBT it’s important to use a thermometer that allows you to measure to 1/10th (98.6) of a degree in Fahrenheit or 1/100th (37.00) of a degree in Celsius. Your temperature doesn’t fluctuate massively in an overall cycle, so you need to be able to see your temperature changes in detail.
This way you can spot your own subtle patterns around ovulation and the start of your next cycle.
Learning the secrets of your unique cycle
Our products use AI to learn about the intricate details of your cycle and your symptoms. We use BBT tracking part of a complex algorithm which can then more accurately predict ovulation. Each cycle creates more data that then helps to refine the predictions we give for the next.Learn More
Why we use hormone testing
We combine BBT with hormone tracking, or to be specific, measuring your levels of Luteinizing Hormone (LH) and tracking other relevant symptoms to help identify ovulation as precisely as possible.
To give you an example, most people think that BBT rises straight after ovulation. This isn’t strictly true. Some women experience a shift in BBT that takes 2-3 days to reach the temperatures it will remain at for the luteal phase - everybody is different. This is why it’s always a good idea to combine BBT with hormone and symptom tracking to get a much clearer idea of when your fertile window is.
When looking to pinpoint the fertile window many women choose to track their levels of LH. For a woman, the levels of this hormone are a good indication of the approaching fertile window and ovulation. LH is created by the pituitary gland and can be found throughout the cycle at low levels. Around the time of ovulation, LH will increase and then decrease rapidly, this surge of LH is what causes the egg to be released. It’s for this reason that we can use the levels of LH to track ovulation.
Many women chose to track LH using LH test strips or Ovulation Predictor Kits (OPK's). OPK’s measure the levels of LH in the urine and are usually held in the urine stream or into a sample of urine for around 10 seconds. Unfortunately, with most OPKs, it can be quite difficult to read the difference between high and peak.

Track your unique LH curve to better understand your fertile window
Ivy reads your ovulation predictor strips and tracks your unique LH curve so you can identify your fertile window with better precision. You can then see more detailed information about your unique LH curve in the Femometer app.
Easy results. Peak, High or Low. Detailed information waiting for you in the Femometer app.
No more squinting at your LH lines to work out your results! See your 'Peak, High or Low' results immediately on the LED display screen, and head to Femometer app to check further data and insights.Learn More
Ongoing tracking - so you can compare your cycles and understand your unique symptoms
By measuring your BBT and LH, alongside tracking other symptoms like cervical mucus, mood changes and physical symptoms, you can more accurately spot your fertile window.
Compare your historical data
Femometer has been designed so that you can log everything you need to help you understand and compare your cycles. For example, when it comes to BBT, an increase after ovulation is what we’re really looking for. But your increase will look different to the next person, so by combining historical data, you will be able to see typical trends and any a-typical measurements.
Create a daily log to spot key symptoms
You can use Femometer to track signs that might be individual to you! Some women have very strange ovulation symptoms that they only recognise once they start a daily log!
Intelligent analysis of all your measurements
Femometer takes all your measurements, symptoms and records into account when analysing your cycle and ovulation. We also look for patterns in your history to offer you insights and tailored advice depending on what we see.
Share your data & charts with your health professional
You can easily download your data and charts and share them with your health professionals, this will save you time as it’s usually one of the first things you will be asked to track and measure when seeking advice for menstrual health problems.
