The basal body temperature will indicate when a woman is most fertile. The device is called the 'Fertility Friend' and measures the body's core temperature, which reveals the most accurate way to determine female fertility rates. This app-connected wearable continuously monitors the user's temperature through the [wearable thermometer](https://www.trendhunter.com/trends/mycelsius-cooling-bracelet) that is placed inside their ear. This high-tech device from Yono Labs works best in the morning after being worn during a full night's sleep. When used regularly, the wearable device will convey information to the [data-tracking app](https://www.trendhunter.com/trends/berry-fertility). Over the course of a month, there is enough data to present when the user is most fertile. The Fertility Friend is an extremely helpful app that can aid couples who are [trying conceive](https://www.trendhunter.com/trends/fertility-tracking-kit), without seeking potentially expensive professional help. ## Trend Insights (Trend Hunter) - Score: 2.3/10 - Popularity: 22% | Activity: 39% | Freshness: 8% - Audience gender: 10% men, 90% women - Primary generations: Gen X - Top markets: North America, Europe ## Categories [Trend Hunter](https://www.trendhunter.com/trends) > [Tech](https://www.trendhunter.com/tech) ## Key Themes ### Why This Trend Is Growing - **In-ear Wearable Thermometers:** There is potential for the development of wearable technology that could measure body temperature for other health purposes like fever tracking and detecting circadian rhythm disruptions. - **Data-tracking Apps for Health Monitoring:** Developing apps that collect personal health data could be useful for health monitoring and identifying personalized treatments for various illnesses. - **Fertility Wearables:** Wearable devices like the Fertility Friend could be used to track fertility and offer hope of pregnancy to couples trying to conceive without seeking professional help. ### Industries Being Reshaped - **Wearable Technology:** There is an opportunity to develop more in-ear wearable technology for health monitoring beyond fertility tracking. - **Fertility Clinics:** Fertility clinics could leverage the use of wearable technology like the Fertility Friend to augment existing treatments and improve success rates. - **Healthcare Apps:** Companies could develop more apps that collect and analyze personal health data to offer personalized treatments for various health issues beyond fertility. ## Related on Trend Hunter - [Smart Fertility Rings](https://www.trendhunter.com/trends/femometer-smart-ring.md) - [Fertility-Tracking Wearables](https://www.trendhunter.com/trends/natural-cycles-nc-band.md) - [Bluetooth-Enabled Fertility Trackers](https://www.trendhunter.com/trends/ovacue-wireless.md) - [Accessible Fertility-Tracking Technologies](https://www.trendhunter.com/trends/cycle-ovulation-powerplug.md) - [Fertility Intelligence Tools](https://www.trendhunter.com/trends/femometer-fertility-tracker.md) - [Menstrual Health-Tracking Rings](https://www.trendhunter.com/trends/femtek-bbring.md) - [Ear-Based Health Trackers](https://www.trendhunter.com/trends/the-lumia-2.md) - [Continuous Hormone Trackers](https://www.trendhunter.com/trends/clair.md) - [AI-Powered Reproductive Platforms](https://www.trendhunter.com/trends/oto-fertility.md)
