Bench mode A live instrument that never stops to think. Rest the phone against a movement and the rate updates as you work — no thirty-second wait, no result screen. Set a reference before you touch the regulator and every adjustment reads as a signed difference from where you started. It also tells you when the reading has settled, so you stop chasing a number that is still moving. Built for iPad A real split view: your collection down one side, the watch or the instrument on the other. On a wide screen a watch's record opens in two columns — identity, controls and service history on the left, charts and readings on the right. Overnight tests that survive the night Recording now continues with the screen off, so an eight-hour run no longer means eight hours of burning display. Readings are written to disk as they happen: if something interrupts the app, you are offered the run back instead of losing the night. Use a better microphone Plug in a USB or wired microphone and choose it in Settings. Bluetooth microphones are offered too, and honestly labelled — they record narrowband audio and throw away most of the tick. A reference clock Network time with a sweep second hand, the offset of your phone's own clock, and how well that offset is actually known. For setting a watch, and for checking one. Temperature, and what it does to your watch Tag a reading with the ambient temperature. Once a few readings span a real range, Isochron works out your watch's coefficient — how many seconds a day it gains or loses per degree — and what a seasonal swing does to it. The wear log A calendar of every day you wore each watch, a timeline, and the numbers: days worn, longest streak, typical gap, the day of the week you reach for it. Tap any day to record or correct it. Your rotation can now be sorted by what you have neglected longest. Also in this release • Export your whole collection as CSV, ready for a spreadsheet • Archive watches you no longer own without losing their history • Fixed the most common crash — starting a measurement after a phone call • Tag readings with what the watch was doing: resting, desk, active, sport • The home screen widget is now translated • Choosing a photo no longer stalls the app while it is processed

Worn accuracy you can trust The rate measured from your photo readings now comes with an error bar, so you can see how settled the number really is. It shrugs off a misread hand instead of being dragged off course by one, spots when a watch has stopped or been re-set, and holds its tongue until your photos are far enough apart to mean anything. A better camera for the dial Closer focus, tap to focus, and a single crisp exposure that freezes the second hand. Photos come out the right way up however you were holding the phone. Bench versus wrist Where both numbers exist, a watch's page now shows how differently it runs on the wrist from how it runs on the timing bench. The forum Photos appear in thread lists instead of a bare link, and a new bell collects replies to threads you started or joined. Fully translated Every screen is now available in German, French, Italian, Japanese and Simplified Chinese — the explanations too, not just the buttons. Also in this release • Insurance reports print on A4 outside the US • Longer battery life while measuring, and on overnight runs • The overnight test now tells you if something interrupted it • Photo readings take up far less space • A reminder when it's time for the next photo reading • VoiceOver can set fractional seconds in the dial editor • More reliable purchases and restores
