Pretty perfect track record This is my third time using Ava to get pregnant- all three times I conceived on the first try. I will say that they tend to get my ovulation date wrong by a day or so (when compared to fertility friend and LH strips)- but it is great combined with other methods, and especially if you come in with information about your own fertility. I’ll add that I also used my Ava to assist with natural family planning for years. Love my Ava!

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!

This is AMAZING In general: I love this product. One star off is for two things: one - the bracelet is sooo tiny it basically was worn out within the first year and I had to replace it. And the other point - sometimes I have an issue with the app telling me “problem to read data” - I just have to synch it more often and it works. Just a bit annoying. Over all - great product. I have only used the regular version of it (not with guarantee) since reading and doing research about this product - I believed (& believe) it works. Otherwise they would not offer money back guarantee. Best purchase ever. If you don’t have PCOS etc. this is a perfect hormone free birth control solution. But you have to be using it regardless & never unprotected intercourse with strangers ! This is my second pregnancy with the help of Ava ! Thank you so much.

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.

Bracelet, app, & customer service are all Wonder I appreciate how much the bracelet and app monitor while sleeping. It's been a great way to learn more about and track my overall cycle and help let me know the best window of time to try for a baby. <3 customer service has always been wonderful and quick to assist with any needs. Also, the pregnant side of the app is very useful for tracking daily changes. Just started using it now and already impressed!
