DON'T WASTE YOUR MONEY DON'T WASTE YOUR MONEY, IT'S A RIP OFF: the customer service is silent and inactive, when it does reply after making me wait for 3 weeks, it is unwilling to refund or replace the product which was still under guarantee. I am shocked for a Swiss company! I bought the bracelet in August 2022. After using it less than 6 times, so almost 2 weeks later, the bracelet started malfunctioning and did not charge properly. I contacted the customer service by email (they have no phone number) several times and waited for at least 3 weeks before receiving a proper reply. I asked to replace the product or refund me. They advised me to do some manipulations, which I did. The bracelet still did not work. I sent them all the photos, videos, and all proof that it was not working, and asked again for a refund. Again, their reply every 3 weeks is: do these xyz manipulations and it will work. Of course, everything they suggested me did not work. I paid USD 300 for this fertility bracelet which stopped working in less than 2 weeks!

Great insights but annoying to charge I love the insights that my Ava app gives me! I'm getting a much better understanding of my cycles! The bracelet is comfortable to wear and the sync is quick every morning. I'm just giving it 4 stars because you need to charge it every day which is quite annoying... But I know that this is the only way you can get some accurate data from so many sensors. I just wonder if all the data on top of the temperature (HR etc) is really useful and whether the tempdrop sensor that doesn't need to be charged would have been enough for knowing precisely when I ovulate.

Second time getting pregnant! Second time getting pregnant using the Ava Bracelet! It's a little spotty on recording sleep, but besides that it has worked great for us on predicting our fertile window. Also love all of the info once you are pregnant, too!

It works but poor customer service and end of life product The app is great it definitely helps you plan for pregnancy or not! The bracelet tracking is spot on it helped me get pregnant with my 1st child. However… the customer service could not be worse. I reached out when trying to track and conceive for my 2nd and the device would not record! It would either say charged n green then die or it would seem like it worked and then fail uploads night after night. I went from zero problems to it not working suddenly. Customer service said oh it’s dead you need to buy a new one. Excuse me? Where n how are we selling products that just die and are end of life while it isn’t described anywhere in advertising or purchasing. No trouble shooting, no coupon towards a new one not even a standard apology statement. I don’t care how well something works; if you have horrible customer service then I’ll move onto many of the other working devices. Do better Ava.

Good for TTC, garbage for tracking pregnancy I've used it consistently for 6 months in order to become pregnant. Prediction of ovulation was correct. Removing 1 star because the braclet band is cheap and the little loops to hold the bands together both broke by 3 months. Another star removed because it is a garbage pregnancy tracker. If you input the conception date (which is in your data! And more accurate that 1st day of last period) it starts acting like conception date is date of last period, so 4 weeks behind. Stupid. And having to toggle back and forth between week groups is annoying, particularly when the scale for your data increases/decreases is visually different from month to month. Expected much better after the TTC interface was so good.
