FAQ

Frequently asked questions

Which iPhones work best with DeepSwing?

Any iPhone on iOS 18 or newer runs DeepSwing well. Newer devices with more capable Neural Engines simply finish the analysis faster.

Do I need Apple Watch to use the app?

No — the Watch is optional. It adds remote start/stop, haptic feedback and quick status, but every analysis feature works with the iPhone alone.

Does DeepSwing upload my videos to the cloud?

No. All pose detection and metric computation happen on-device. Videos stay in your library and are only shared when you actively export them.

Can I use slow-motion footage from the iPhone camera?

Yes. Import high-frame-rate clips from Photos, or record in-app and review with 0.25× slow motion and frame-by-frame scrubbing.

How is this different from a launch monitor?

A launch monitor measures ball flight; DeepSwing analyzes your body and club movement from video and estimates speeds. Many players use DeepSwing for technique and a monitor for ball data — the app also offers a launch-monitor-style speed mode.
