Wear the Ava bracelet at night for effortless insight about your cycle, your fertility, and your health. Ava is clinically proven to detect the very beginning of the fertile window—in real time, as it happens. That’s totally different than OPKs, which only detect the last day or two of the fertile window, and the temperature method, which only confirms ovulation after the fact. Ava also tracks your sleep, physiological stress levels, and resting heart rate—so you can see whether your lifestyle is supporting optimal health.
