How can we help?

SwingLog requires iOS 14.0 or later. We recommend updating to the latest version of iOS for the best performance and Bluetooth reliability.

Go to the SwingLog app → Settings → Add Sensor. Make sure Bluetooth is enabled on your iPhone and that the sensor is charged and powered on (hold the button for 2 seconds). The app will detect the sensor automatically and guide you through pairing.

The sensor battery lasts 8+ hours on a full charge, which covers multiple sessions. You can check the battery level anytime in the app. Charge via the included USB-C cable — a full charge takes about 90 minutes.

The SwingLog sensor is splash-resistant (IPX4 rated), meaning it can handle light rain and sweat without issue. However, it is not designed for submersion. Avoid submerging it in water or leaving it in heavy downpours.

Yes! SwingLog's mount is designed to fit any standard padel racket grip. The silicone band fits grips between 4.0" and 4.5" in circumference. The sensor adds less than 20g to the end of the handle, so it won't noticeably affect your play.

This is usually a Bluetooth range or interference issue. Make sure your iPhone is within 30 meters of the sensor and there are no other heavy Bluetooth devices nearby. Try closing other apps and toggling Bluetooth off and back on. If the issue persists, try removing and re-pairing the sensor in Settings.

After ending a session, go to the Session Detail screen and tap the share icon (↑) in the top right. Choose "Export CSV" to save the file to your Files app, AirDrop it, or share it via email. CSV export is included in all plans.

The sweet spot is the central zone of your racket face that produces maximum power and control with minimum vibration. SwingLog's IMU sensor detects the impact quality of each shot and calculates what percentage of your hits land in that optimal zone. A higher percentage means more consistent, powerful shots.

You can delete your account and all associated data at any time from Settings → Account → Delete Account inside the app. This action is permanent and cannot be undone. Alternatively, email us at support@swinglog.com and we will process the deletion within 72 hours.

First, connect it to a charger for at least 30 minutes. If the LED still doesn't light up, try a different USB-C cable or charger. If the problem persists after a full charge attempt, please contact our support team — we may need to replace the unit under warranty.

SwingLog's algorithms are currently optimized for padel. While the sensor physically works on other rackets, shot classification (forehand, bandeja, smash, etc.) and sweet spot tracking are specifically tuned for padel mechanics. Tennis and pickleball support are on our roadmap!
