About this app
Enhanced App Store Description The most complete, precise, and effortless way to track your watch’s accuracy over time. Whether you’re a casual owner or a serious collector, WatchWatcher helps you understand exactly how your timepieces are performing—day after day, week after week. Powerful timing tools • Add timing events in two ways: a simple manual tap or automatic extraction from an image. • Reset your watch to an accurate reference time and continue tracking seamlessly—the app can recalculate all past events with a single instruction. • View a beautiful, full-size graph in your browser showing all your watches at once. Insightful accuracy data • Switch between absolute difference and rate drift to see your watch’s behaviour from every angle. • Discover how your watch compares to others—both across all users and within its specific brand. • See average drift across all time, or focus only on the most recent two events. Smart predictions that save time • When you log a new event, WatchWatcher predicts where your watch should be based on historical drift—minimising adjustments and speeding up logging. • Fine-tune prediction behaviour in settings for even more accuracy. Import, export, and stay in control • Easily back up or migrate your data with iCloud import/export or CSV. • All online features work without creating an account. • No subscriptions, no in-app purchases—just powerful watch-tracking tools, free and private.
