Daysy Fertility Monitor 2.0. Gently used, excellent condition. Still works and charges great. I used this for a year (successfully) but have switched to a different birth control. I have factory reset the device and unpaired it from my account - shes ready for a new owner! I’ll also include the original charging cable, the hand knit sweater (so cute) and the O Case which is amazing for protecting the device while traveling. I used the case so many times for trips and it worked perfectly. Any questions please ask! Daysy has also been fully sanitized but I’ll also include a few alcohol prep pads for you to re sanitize when you receive it. Daysy has a companion app that is free from the App Store and there’s no monthly subscription fee to use it. You just purchase the device and have access to the app / algorithm forever - for free (way cheaper than natural cycles)
