What are fertility trackers?

Fertility trackers are apps or devices designed to help people monitor their reproductive hormones and health to optimize their chances of conception. Some of the widely used tools are basal body thermometers, fertility apps, smart rings, and test strips.

These monitors help individuals trying to conceive, track fertility signals, such as cervical mucus condition, hormone levels, ovulation, menstrual cycles, and basal body temperature.

Many women report more successful conception rates after using modern fertility trackers compared to traditional methods. Yet the effectiveness of fertility trackers lies in your data input and the accuracy in predicting ovulation and fertile windows.

Modern fertility trackers, such as those that incorporate hormone testing and advanced algorithms, have shown to be particularly reliable. Additionally, the convenience and ease of use of these devices make them a popular choice for many individuals looking to take control of their reproductive health.

Fertility trackers can range in price from very affordable to pretty expensive. Be sure to keep your budget when choosing a fertility tracker.

What is the best fertility monitor?

Based on our review and customer feedback, Mira is the best fertility monitor. Users appreciate its ease of use, which makes the tracking process straightforward and accessible.

Technical issues are minimal compared to other monitors, contributing to a smoother tracking experience. The monitor detects the activity of 4 essential fertility hormones helping women to catch the peak ovulation days for possible conception. Couples may also use Mira as a birth control tool.

What is the best fertility app?

Our winner in the category of the best fertility tracking app is Flo. It emerges in the field of women’s health as a leading choice by more than 100 million women for several reasons.

Fertility tracking: why is it essential?

Fertility tracking allows women to obtain insights regarding their reproductive health. It is essential to track fertility if you are trying to get pregnant and want to keep a close watch on your cycle to pinpoint the best time to attempt conception — that is, peak ovulation day.

In addition to helping with conception, fertility tracking can also provide valuable information about overall health. Changes in menstrual cycle length, the presence of irregular bleeding, or other abnormalities can be early indicators of underlying health issues that may need attention. Regular fertility tracking can empower women to take control of their reproductive health and seek medical advice if needed.

The main benefits of fertility trackers

There are several benefits of fertility trackers, including:

  • Period tracking
  • Facilitating or preventing pregnancy
  • Tracking irregularities
  • Analyzing premenstrual symptoms
  • Pregnancy tracking

Despite the increasing number of fertility tracking apps and monitors and TTC platforms providing anecdotal experiences, talk to your healthcare provider, especially if trying to prevent pregnancy or TTC.

Fertility tracker apps vs. monitors

Fertility tracker apps and monitors serve as valuable tools for monitoring menstrual cycles and predicting fertile days. Here are the main differences between apps and monitors for fertility tracking:

  • Accessibility. Apps are easily accessible on smartphones, while monitors are standalone devices.
  • Data input. Apps rely on user input for tracking cycle data, while monitors may offer more direct and precise measurement methods.
  • Features. Monitors often provide more comprehensive data, such as hormone levels, whereas apps may offer basic cycle-tracking features and predictions based on data input.
  • Cost. Apps are typically more affordable or provide free versions with essential features, while monitors may be highly priced and require an initial investment.

Experts do not recommend using fertility tracker apps on their own as a form of contraception. Condoms or other birth control methods are recommended in addition to the fertility awareness method if the goal is to prevent pregnancy.

When to see a doctor?

You should see a doctor, specifically a reproductive endocrinologist or OB-GYN if you are planning a family and experience the following difficulties:

  • Irregular cycles
  • Diagnosed or suspected health concerns
  • Fertility issues with the male partner
  • Hormonal imbalance
  • Recurrent miscarriages (chemical pregnancies)

For individuals above 35 years old, it's advisable to consult a doctor if pregnancy hasn't been achieved after six months of active TTC. For those below 35 years old, seeking medical advice is recommended after one year of unsuccessful attempts at conception.

Best fertility tracker app 2024: conclusion

In conclusion, fertility tracker apps and monitors can serve various purposes, including providing insights to help with conception or the opposite — preventing pregnancy. What’s more, seeking the best fertility tracker suitable for your needs requires a thorough consideration of safety, accuracy, intuitive design, and cost-effectiveness.

Nonetheless, it’s essential to take additional steps to enhance fertility and general reproductive health by talking to your OB-GYN and making healthy lifestyle changes.
