Best Fertility Apps BadgeGlow stands out as the best fertility app due to its combination of useful features, robust educational resources, and active user community. But if Glow doesn’t end up being the best fit for your needs, you should check out the nine other top fertility apps that we’ve reviewed below.

Top 10 Fertility Apps to Try

How We Chose the Best Fertility Apps

To determine the top 10 fertility apps, we looked for features such as ovulation tracking, basal body temperature monitoring, and notifications. We also sought out providers that offer a version of their app that is always free.

Choose the fertility app that’s right for you

Some apps are designed for users who are attempting to get pregnant. Conversely, other apps are more focused on helping users with birth control. Before you select your fertility app, make sure that its features are aligned with your needs.

Privacy and security

With the amount of personal health information that is typically stored in fertility apps, privacy and security are highly important factors to consider. We recommend apps that include features such as customizable notifications, anonymous forums, and password protection.
