Frequently Asked Questions

A ball is NOT required for automatic swing detection.

8–12 feet is a good starting point. Ensure your body and club remain in frame from address through follow-through.

Yes. Hitting bays, garage, basement - wherever you have room to swing. Prioritize bright, even lighting and avoid strong backlighting from windows.

Select "left handed" when launching Practice Mode on the iOS app. From there, everything should work as expected.

Yes, Practice Mode on iOS requires an internet connection (even if you are not using the web app).

For best results, use a strong and reliable WiFi connection. 5G cellular connections work as well, but be sure you have good reception.

Parallax CAN be used solely as a way to capture and review swings on your iOS device.

However, for the most effective experience, we highly recommend using a second device to watch your swings during your practice sessions if possible. Getting near-immediate feedback on your swing is the best way to groove new motor patterns in your brain.

Replays typically appear within a few seconds after follow-through. With a strong connection, this delay may be as low as two seconds.

Full analysis is populated shortly thereafter (typically within 10 seconds). The first swing of the session may take a little longer to populate.

If you are not seeing these results, it may be us, or it may be your network connection. Check out fast.com to test your connection speed and latency. See the troubleshooting section below for more tips.

No. They just both need an internet connection. No pairing or other connection steps required.

We recommend keeping the device awake and plugged in for long sessions. If the screen locks, reopen the app to resume Practice Mode.

Incoming calls, "low battery" notifications, and other device-level interruptions will pause swing detection.

Parallax uses computer vision and motion analysis algorithms to automatically identify when you make a golf swing during Practice Mode. The app continuously monitors the video feed and triggers a clip recording when it detects the characteristic motion patterns of a golf swing.

We aim to minimize both missed detections and false positives. If you are having issues with either of these, please reach out to us at support@parallaxgolf.ai

While we strive to make club tracking as accurate and reliable in as many environments as possible, it is not perfect.

The most frequent reason for missed club tracking is lighting: tracking the clubhead accurately during the ultrafast downswing requires a lot of light in order to achieve a fast shutter speed.

Ironically, TOO MUCH light in the background can also cause issues. If the sun is visible in the background or is reflecting a lot of light off of the clouds, the camera may have no choice but to reduce the sensitivity of the capture. This results in fewer fine details available for analysis in the video.

Bright, direct lighting, with the light coming from BEHIND the camera is ideal. In other words, your shadow should fall away from the camera. If swinging indoors, set up a lamp or two behind the camera for best results.

If you are having ongoing issues with swing plane detection, please reach out to us at support@parallaxgolf.ai

We support the Down The Line capture angle (i.e. parallel to your target line; camera facing the target).

We will be launching Face On in the near future.

Yes. Parallax offers unlimited swing video capture and storage for actively-subscribed individuals.

For multi-player situations (teams, academies, clubs, facilities), please contact us about team/facility plans:

At this time, we plan to continue offering access to your swing library even after a subscription is ended, but do note this policy may change in the future. If this policy does change in the future, we will give you a heads up in advance.

If you delete your account altogether, however, your videos and analyses will also be deleted and will not be recoverable.

From the swing view, use the delete action to remove a clip from your library. This can be done from either the web or iOS app.

Yes, Parallax provides multiple export options from the iOS app:

• Export original unmodified videos
• Export videos with analysis overlays

Find this option in the menu in the iOS app while viewing the swing you want to save.

This will save the video to your device's camera roll (iOS Photos app).

Swing videos are stored securely in the cloud associated with your Parallax account.

Yes!

Look for the button in the iOS app or web application while viewing the swing you want to share.

Ask your recipient for their username, and enter it in the "SEND TO USERNAME" field.

NOTE: you must create a username before you can share swings; you can do so in the Settings menu of the iOS app.

Yes, once a golfer sends a swing to a coach, the coach can record voiceover feedback on the swing while reviewing it in the app. Everything the coach does during the feedback recording session will be included - drawings, swing comparisons, path overlays, etc.

Yes. Contact us for team/facility subscriptions to enable multi-user workflows and shared spaces.

Manage your subscription from your account settings. Changes take effect on your next billing cycle.

Your videos remain associated with your account; capture and advanced features require an active subscription.

At this time, we plan to continue offering access to your videos for a buffer period after your subscription ends, but this is not guaranteed.

Confirm camera alignment, keep the golfer and club fully in frame, and improve lighting. Restart Practice Mode if needed.

Most importantly, confirm your internet connection. Swing detection itself does not require internet access, but the swing upload and analysis step does: what may feel like missed swing detections may actually be caused by a flaky network connection.

Use a strong Wi-Fi network (or strong 5G), keep the iPhone plugged in, and use Safari or Chrome on the replay device.

Verify network connectivity and refresh the page.

If the issue persists, please reach out to us at support@parallaxgolf.ai

The combination of the sun's rays and the phone's increased processing load can cause the device to heat up quickly while in direct sunlight. This may result in a temporarily degraded experience (slower replays, missed detections, etc.).

If you're practicing outdoors on a warm sunny day, try to find a shady spot or use an umbrella or other sun shade for your devices. Even propping a hat up next to the phone to reduce direct sunlight can help.

For longer sessions, keep the iPhone plugged in and reduce screen brightness. There's no getting around it: the analysis performed by the app sometimes requires some heavy lifting by the processor.

Typically, logging out and logging back in will resolve a large class of issues (iOS app and web app).

If you're observing something particularly odd or are having ongoing issues, please reach out to us with as much info as possible at support@parallaxgolf.ai.

Only you. Swings aren't visible to other users unless you share them.

Yes, from the web app, select the button while viewing the swing you want to share, then click "Public link".

We collect basic product analytics to improve reliability and user experience. We do not sell personal data.

Review our privacy policy for more details.

Our iOS app supports iPhones running iOS 17.3+.

We recommend Safari or Chrome on a tablet, desktop, or sim computer for best results.

Other browsers may work, but they are untested. Many lack specific features we rely on for the best video playback experience.

The Face On view capture angle is under active development (ETA: Fall 2025). We are also working on an expanded set of metrics and analysis features.
