Rehearse on a rhythm — SyncDance now opens to a calendar. • Calendar home — every practice session lands on the day you danced it, so your progress is easy to see at a glance. • Solo sessions — save a single clip, not just side-by-side compares. • Batch import — bring in a whole set of clips from your library at once. • Search — find any session in your library by name. • Jog-wheel fine-tuning — nudge the alignment on any compare by hand. • Sharper auto-sync for slowed-down clips (0.75× / 0.5×). • Recording and export fixes, plus performance improvements.

Fancam is here — turn any clip into a solo cam. • Fancam: tap a dancer and SyncDance tracks them through the whole routine, generating a smooth, auto-framed close-up right on your device — up to 4K. Apply it straight to your side-by-side Compare. • Export upgrades: choose 1080p or 4K per pane, with slow-motion / speed-adjusted exports baked in cleanly. • Recording fix for the latest iPhone front cameras, so your takes always come out upright. • Assorted polish and stability improvements. Happy dancing!

• iPad support — SyncDance is now a native iPad app. Compare, record and review on the big screen, in any orientation, with a side-by-side layout that finally has room to breathe. • Record Along fix — fixed a bug where your take could be captured sideways on some iPhones. Your recordings now stay upright on every device. • Added a "Contact us" option in the Me tab, so it's easier to reach out.

• Note captions on the video — In a side-by-side comparison, enter Note Mode to mark a moment and your note now appears as text right on the footage. Drag it anywhere, pinch to resize, and change its color. Turn on "Bake in notes" when you export to keep the captions in the video you share. • Sign in with Google — Create an account or sign back in with a single tap, and keep your practice synced across all your devices. We've also improved the accuracy of the automatic alignment between your take and the reference clip, and fixed a crash that could occur when starting a comparison.

NEW Record-along: film yourself dancing to a reference clip. Pick the clip, set the section, speed and a spoken countdown, then dance while the front camera records just your video. The original's clean music plays the whole time and is muxed in automatically, so there's no microphone and no echo. You land straight in a synced side-by-side compare, and your take is saved to Photos.

Notes — mark any moment in a comparison with your comment and SyncDance saves a frame-accurate side-by-side snapshot with your note. Jump back from the timeline; notes sync across your devices. Fixed some bugs when exporting videos.
