Start tracking your cycle in no time.

Download the Ava app and create an account.

The Ava app is available on the App Store and Google Play store. Once you’ve downloaded Ava, follow the onscreen instructions to create your account.

Pair the Ava bracelet by plugging it in. Follow the instructions on your app screen.

You will be asked to pair your Ava bracelet with the app. Follow the instructions on the app screen; plug Ava to a standard USB adapter or your computer. Make sure that location services and Bluetooth® wireless technology are both enabled on your phone. It might take a few seconds until your Ava bracelet is recognized by the app. You can unpair and pair your Ava anytime in the ‘my Ava bracelet’ menu.

Charge Ava for two hours before your first use

While Ava is charging the LED light is flashing white. Once your Ava is fully charged the LED light turns solid white. Always make sure to charge Ava during the day so it is ready to record before sleep.

First Time Use

Start using Ava on any night of your cycle. Once your bracelet is paired and fully charged, follow these steps to ensure the highest level of accuracy.

Find the right fit. Ava will vibrate to confirm it is ready to record.

Wear Ava every night on your non-dominant wrist and in the same strap notch to ensure consistency. The fit should be snug and flush to your skin, but not too tight. A vibration will confirm Ava is ready to record.

Wear Ava to bed at night for at least four hours.

Ava needs your body at rest in order to track your physiological parameters consistently over time. Wear the bracelet overnight for at least four hours. Set the optional alarm to wake up to a gentle vibration.

Sync your data in the morning.

In the morning, tap the sync button in the app to upload your data. View your fertile days, along with nightly and cumulative results. Ava may adjust your fertility predictions upon syncing.

Enter your period.

Day 1 of your period is the first day of your cycle, so be sure to enter the days you menstruated or correct Ava’s period prediction on the day that it starts. Also, don’t forget to log each day of your period.

Use Ava consistently.

The accuracy of Ava’s algorithm improves with every cycle you record, as it draws from both current and past physiological data. It’s also important to wear Ava every night, from the first to last day of your cycle.

Support & Helpful Information

Having issues getting your Ava up and running? We’ve collected the most common issues that might come up. If you can’t find what you’re looking for here, check our FAQ page. Our customer support team is also here to help.

Should I wait until the first day of my period to start using Ava?

Start wearing Ava as soon as you receive it, no matter where you are in your cycle.

If you first start wearing Ava in a cycle where you haven’t yet ovulated (if you’re still in your follicular phase), then Ava will start working immediately to detect your fertile window in real time.

If you first start wearing Ava in a cycle where you have already ovulated (if you’re in your luteal phase), then Ava will use the date of your last period to estimate when your last fertile window occurred. As soon as you enter the date of your next period, Ava will begin detecting your next fertile window using the physiological data it gathers.

Ava predicted the wrong day of my period. How can I change it?

When Ava predicts your period to happen, for example today, a pop-up window will remind you to edit confirm or remove the period.

Simply click the + icon and you will be able add or remove a period.

If you are confirming a period, you select how heavy your flow is, and you will see this change immediately at the top of the screen, and the date where you confirmed you have your period should now be encircled in a solid pink bar. Click the checkmark (Android) or select Done (iPhone) to confirm your selection.

If your period hasn’t started yet, you simply de-select the highlighted flow and this will remove the period. Click the checkmark (Android) or select Done (iPhone) to confirm this change.

The start date of your predicted period will now be pushed back to tomorrow.

Please note that future predicted periods cannot be changed.
