1.6.1
August 31, 2026
Accuracy tracking gets more precise, plus a round of fixes. • Fine Adjust added: nudge a reading by a fraction of a second when the second hand sits between the indices from a photo measurement. • Every reading now shows two rates: how the watch ran since your last reading, and its average since the baseline. • Wear history is now a readable table, and tapping a day with a reading opens the full reading card. • Accuracy charts add per-batch averages and 30, 60, 90, and 180-day ranges. • Fixed: a watch's wear history and its accuracy history could report different drift rates for the same reading. • Fixed: certified watches (COSC, METAS, Rolex Superlative) are now always judged against the certification's own thresholds. • Fixed: "Rank This Month" no longer sticks to last month.
