Before start using the Smart Dampener you need to setup your app and pair the device with your phone.

Follow instructions in this step by step video: http://vimeo.com/263359183

First, you need to ensure that you followed all steps to set up your app and pair your device with your phone during setup. If you haven't paired your device, you can click on the battery icon in your app (top-left corner) and follow the steps (see video: http://vimeo.com/263359183)

If you have completed the initial pairing and still having issues with syncing, you may need to upgrade your firmware:

1. Open the app, and click on the battery icon (top-left corner).
2. Turn the device on (one press).
3. Put it in "Sync" mode - once you see light goes in circle, press the button one more time (you should then see lights on both sides go up).
4. In the app you should see within a few seconds "Last Sync:" updated to your current date and time.
5. If the firmware version is the not the latest you will have an option to upgrade your firmware. To upgrade firmware, you need to fully charge your device first. Follow the steps in this video: https://vimeo.com/266056858

This means that the device requires special firmware upgrade. You need to fully charge it first (plug it in for charge for 2-3 hours) and then follow the instructions in this step by step video: https://vimeo.com/265506079

This means that the battery is running low and it needs charging. Plug it in for 2-3 hours to let it fully charge and then try turning it on.

The device is attached exactly the same way as a regular vibration dampener by pulling two middle strings apart to make room for the device to slide in.

Turn the device on by pressing the button and wait until the light goes in a circular pattern ("Play" mode). That’s when the device is “listening” and collecting data.

When the device is in "Play" mode (light goes in a circular pattern), press the button (short press) and wait until the lights on both sides go up (that's "Sync" mode). Open the app and wait 5 to 10 seconds until the new session appears.

Press the button until the lights turn off.

The device is designed to provide same feel as a regular vibration dampener. It does not affect the balance of the racket, which is critical to keep the same feel of the racket during the swing. In addition, the shell of the device is made out of silicon that is the same material that regular dampeners are made of. The device attaches to racket strings exactly the same way as a regular dampener does, resulting in soft dampening feel during the impact with the ball.

The weight of the device is 0.22 ounces (6.2 grams).

The battery lasts 5+ hours.

Yes, the device can be attached to any tennis racket whether it’s an adult racket or a junior racket. The data and the metrics will not be impacted by the specifications of the racket and will provide same accuracy regardless of which racket is used.

You can use the supplied cable and any USB power outlet including your computer to charge the device. When the device is charging, the lights will go up and down. When fully charged, all lights will lit up.

No, all of your data is saved in the cloud. When you install Courtmatics app on your new phone, login with the same Facebook account and all of your historical sessions will be automatically downloaded to your mobile phone from the cloud.

In the app, tap the battery icon in the top left corner and select “Forget this Dampener” on the bottom of the next screen. After that the app will guide you to pair a new device (all of your historical sessions will remain on your phone).

The accuracy for all metrics is at least 95% based on a test group of 300+ beta testers from beginners to high performance players. Collecting motion data right from racket strings provides highest possible accuracy for measurements.

For every session there is an option to set it as a “match” or a “practice”. In the trends section of every metric you can set the filter to view your trends by session type.

Highlight is a record that the player sets during the session when compared to all prior sessions. If there are multiple records being set during a single session, one of these records will be chosen as the most interesting to show.

After you synced the device with your app, tap the battery icon in the left top corner to see % of battery life remained and the remaining duration of play time on this charge.

Currently, the app is released for iOS platform only (version 8.0 and later). Android is coming up soon and we will notify when we release our app on this platform.

The benchmark to achieve a score of 100% is based on the performance of Division 1 College tennis players. Performing in the green zone (70%+) is a good result, while getting to 95% is a high performance College level result.
