Whether you’re struggling to conceive or just starting on the journey to conception, Ava helps you achieve your baby goals faster than other methods.
Properly timing intercourse can double a woman’s chances of conception, 1 but as many as 75% of couples get that timing wrong. 2 Why? Because the fertile window is more than ovulation day. It’s also the 5 days leading up to it, with peak fertility 2 to 3 days before ovulation3.
Ava is clinically proven to identify your unique 5-day fertile window as it’s happening—letting you know when you’re ready to conceive up to 4 days earlier than LH tests, and with 50% more precision than the calendar method used by typical period-tracker apps. 4
Go beyond ovulation. Take control of your cycle and make every fertile day count.
Syncs with iPhone and Android. Tested for cycles of 24 to 35 days.
