Phebe
Not very accurate and makes up data
Not very accurate and makes up data. It never properly predicted the start of my next cycle or my ovulations. (I had the textbook 28 day cycle and it still couldn't figure it out). I continued to use it even after I was pregnant and it still continued to report ovulation days recognized by biphasic signal patterns. Don't waste your money on an expensive sleep bracelet that reports false information.

Dear Phebe first of all we'd like to thank you for your very honest feedback - it's truly appreciated. We are sorry to hear you didn't like your experience with the Ava bracelet and would like to hear more about it in order to be able to solve certain problems immediately and provide you with a much better experience. Please write to [email protected]. We will try to figure out what caused the trouble in order to make using our product valuable for you. Please do know, that Ava's built-in fertility detection feature is accurate only for cycles between 24 – 35 days and the bracelet needs to be worn every night for at least 4 hours during sleep. If you want to use it in pregnancy mode, please switch modes within your App - you should then no longer get predictions on your fertile window, but instead weekly updates for your pregnancy. Warm regards, the Ava team.
