Version 2.1.1
Long sessions save at once. Side-by-side recordings are now combined while you record, so even long sessions are saved to Photos the moment you stop.
In sync to the end. Face-on and down-the-line now stay in sync over long recordings.
Nothing lost if the app closes. If the app closes during a recording, the footage up to that point is saved to Photos the next time you open it (when Photos access is allowed).
Version 2.1
One video, two angles. When two devices show face-on and down-the-line side by side, your recording can now be saved as one video, with both angles lined up to the same moment. Compare them or share them straight from Photos.
Your choice of files. Choose how it's saved in the Monitor's Settings under Side-by-Side Recording: one combined video, two separate videos, or all three.
Resize the split view. Drag the divider to give face-on or down-the-line more room, and double-tap it to reset.
Picture-in-picture. One angle fills the screen and the other sits in a small window you can drag anywhere and resize from its corner. Tap the window to swap.
Version 2.0.1
iPhone Duo. It uses the outer camera when folded and the inner camera when open, switching automatically to match the screen you're looking at.
The Camera's screen dims. With two devices, the Camera's screen now dims after 30 seconds without a touch, which cuts heat and battery use. Tap to bring it back.
Frame rate note. When the Camera captures more frames per second than the Monitor can display, Settings now tells you.
iPhone SE. The message about the paused face-on camera now appears on the face-on side of the split view.
Version 2.0
Side-by-side view. With two devices, the Monitor can also show its own front camera next to the Camera's view, at the same moment: face-on and down-the-line, side by side. It is on by default (“Show this device's camera too” in Connect Two Devices). Recording saves both videos.
Mirror button. The new button at the top right flips the picture left to right. Your choice is remembered for each camera.
Show on TV. With Screen Mirroring to an Apple TV or AirPlay TV, the TV shows just the delayed video, full size. How to start it is at the bottom of Settings.
Ultra wide. On devices with an ultra wide back camera, pinch to zoom the Main camera out to 0.5× and fit your whole swing in, even in a narrow bay.
When the device gets hot, the app lowers the frame rate automatically and tells you, so the delayed video keeps running. It goes back once the device cools down.
Pro is now an annual subscription, with the first month free for new subscribers. If you already bought Pro, nothing changes: it stays yours. The purchase screen shows the date your free month would end, and Settings shows when your free trial ends.
Placement guide. It opens the first time you launch the app and shows where to put the device when you use one device or two. Open it again at the bottom of Settings.
Clearer help when two devices don't connect. After a few seconds, Connect Two Devices lists what to check, with any problem the app finds at the top. Once connected, it shows the connection quality and what to do when it's weak.
Version 1.0
The first release of Golf Swing Partner.
Delayed playback, hands-free. The screen keeps showing what the camera saw a few seconds ago — 2 to 20 seconds, 6 to start — at normal speed and full screen. Switch between Live and Delay with one tap. Nothing to press between shots.
Your camera at its best. The front camera, to watch yourself like a mirror, or the main camera on the back. Resolution and frame rate up to your device's maximum (up to 4K and 240 fps where supported). Pinch to zoom.
Two devices. Film with one device and watch on the other. They connect directly to each other, with no Wi-Fi network or router; after a 4-digit code the first time, they reconnect by themselves. Change the Camera's settings and zoom from the Monitor.
Recording. Tap to start and tap again to stop. The video is saved to the Photos app, without sound.
Free and Pro. Delay playback on one device is free with no time limit, and the two-device link is free for up to 5 minutes. Pro, a one-time purchase, removes the time limit and adds recording.
Five languages. English, Japanese, French, Spanish and Korean. No account, and no data collected.
