What's new

Swing video, properly. Every swing gets Crest, Axis and Tilt overlays, saved right on your iPhone. Open any swing full screen to jump straight to TOP and IMPACT, step through it frame by frame, and run it all from your Apple Watch.

• Crest, Axis and Tilt overlays. Your hand path with your Crest marked, a tube around your body that shows rotation against sway, and your shoulder, hip and spine lines from address to impact.
• Saved videos. Every swing your watch reads is recorded and kept on your iPhone. Manage them in Settings → Your Data → Saved Videos.
• Full screen. Jump to TOP and IMPACT, step frame by frame, slow it down and mirror it, with your four numbers under the video.
• Your watch as the remote. Open any swing from the shot list on your watch, then switch the overlay, replay it, go live, change the speed, mirror it or delete it from your wrist.
• A refreshed watch screen. Your arc, tempo and Crest, with the remote one tap away.
• A simpler Settings. Tolerance and Clubs each have their own screen.
• A level on the live camera, in the regular view and full screen, so you can set the phone up straight.
• Every number comes from your watch. Backswing, downswing, tempo and Crest are always measured on your wrist, for every swing.

Japanese, and a set of corrections that are all about the same thing: not claiming more than the watch actually knows. Nothing in this release changes how a swing is measured, so sessions from 1.0 and 1.0.1 remain directly comparable.

• Japanese. Every screen on both devices, reviewed by a native Japanese golfer, and checked on the smallest iPhone and the smallest Apple Watch.
• A swing that wasn't read no longer pretends to be a new one. When the watch couldn't read a swing, it redrew your previous swing's arc — which looked exactly like a fresh reading, except the Save button was already spent. Now the screen holds still. An accepted swing buzzes your wrist; a rejected one doesn't, and that silence is the signal.
• The Health warning now works — a correction to 1.0.1. That release said it surfaced a denied Health permission. It did not. The app was reading a value Apple never sets, so tapping Don't Allow was recorded as granted and the warning could never appear for anyone. It now reads the permission itself and watches whether the keep-alive session actually starts. A red marker appears at the top of the swing screen and opens the full explanation.
• Your Tolerance setting reaches the watch. Relaxed, Standard and Strict were set on the phone and never sent, so the watch always judged against Standard. The same session could read green on one device and red on the other.
• No color until there are enough swings to mean it. A club with one swing has no spread, and it was marked red — as though you had missed a target that couldn't be measured yet. Spreads now stay grey until three swings back them.
• Interpretive sentences removed from the watch. Lines like "your tempo is repeatable and consistent" could appear off a single swing. They restated what the colored number already said, and they are gone.
• Readable outdoors. Small grey text failed the contrast standard on both devices. It is lighter now, while staying clearly quieter than the numbers beside it.
• Nothing cut off on small iPhones. The app name truncated to "Tornu…" on an iPhone SE or mini — in English as well as Japanese.
• A cancelled or renewed subscription is noticed straight away rather than at the next cold launch.

Six fixes, all about the same thing: telling you when something is wrong instead of failing quietly. Nothing in this release changes how a swing is measured, so sessions from 1.0 remain directly comparable.

• The phone now says when no Apple Watch is paired. Tornu can't produce a swing without one, and previously it never said so — you got an empty screen and no explanation.
• A denied Health permission is surfaced. The workout session is what keeps the sensors alive when the screen sleeps. If you'd declined it, the recorder stopped mid-bucket with no way to find out why. This did not work. The check was reading a value Apple never sets, so the warning could never appear. Fixed properly in 1.0.2.
• The paywall shows no price rather than a stale one. If the store can't be reached, prices are left blank instead of falling back to US dollars — which would have been wrong for everyone outside the States.
• Club lengths removed from the watch's club picker. The phone dropped them a while back; the watch was still showing them. Consistency fix.
• A corrupted club bag is rescued, not overwritten. The file is copied aside so nothing is lost, matching how session data was already handled.
• The watch reports a failed history load. It used to show an empty list, which looks identical to having no sessions.

First release. Two metrics, measured on the wrist at a hundred samples a second, with a deliberate refusal to estimate anything the watch can't see.

• Tempo — backswing and downswing timed from the reversal at the top to impact, at 10 millisecond resolution, reported as a ratio.
• Crest point — where in the downswing your hands gained speed fastest, from 0 at the top to 1 at the ball. Validated against deliberately cast and deliberately rushed swings, both of which read measurably lower.
• The arc — your swing drawn as it happened, colored by your own acceleration, with the crest marked. The straight bar beneath it is the same data unrolled flat in time.
• Per-club spreads — every metric carries a ± measured within each club and never pooled across clubs, colored against a target you set to relaxed, standard or strict.
• Camera re-timing — prop the phone up and the front or rear camera can time the downswing more finely than the watch alone, at roughly 120 or 240 frames a second. The watch still decides that a swing happened, and crest always comes from the watch.
• Video replay — the recorded swing plays back on the same clock as the arc, so the two cannot drift apart.
• Review and trend — every saved session with its full shot list, plus a chart of tempo, crest and both spreads across days, filterable by club.
• Works with anything you swing — a club, an impact trainer, or nothing at all. Tornu measures your wrist, so all three read the same.
• No account, no server — everything stays on your iPhone and Apple Watch. Backup and restore are manual and merge rather than replace.
