Whether you're trying to get pregnant or not trying to, one thing is constant throughout fertility. Women monitor their fertility to know when it's easiest to get pregnant, which can help in either situation. Some trackers cost hundreds of dollars, like the Apple Watch 9, while some have free apps, but each device has unique features. Here are five different trackers to help you with fertility monitoring and family planning. (Note: we did not include an Apple Watch (version 8 or later) which can track a woman's ovulation because it does so via a wrist reading. All the devices below do not use a wrist reading to monitor your body's temperature.)

MiraMira works with a free app that pairs over BluetoothMira


Mira is a tracker that works with a smartphone iOS and Android app to let you see hormone levels in detail. The device pairs over Bluetooth. The app is color-coded, so you can see when specific hormones are at their highest and what that means in terms of fertility.

Mira costs $199 and comes with ten single-use trackers or wands to start. You can order additional packs of 20 for another $59.
