Watch Tracker - Collection

About this app

Measure how your watches really run - day by day. Watch Tracker helps you record accuracy, spot trends, and catch issues like magnetism, all with a clean workflow made for collectors and tinkerers. Build your collection - Add each watch with a friendly guided form (help tips included). - Edit or remove any time—by default you can track one watch; unlock unlimited with a one-time in-app purchase. Record accuracy in seconds per day (SPD) - Start a measurement and tap when your watch matches the reference time. - We color-code the result (fast/slow) and calculate seconds per day, the standard way enthusiasts and chronometer tests express rate. View history charts and long-term trends to see how your regulation or service impacted performance. wristlog.com Smart reference time - The app fetches an atomic-time-disciplined reference (with a clear progress spinner). If the network is unavailable, it gracefully falls back to device time so you never lose a session. Capture real-world context - Add an optional note and watch position (dial up, dial down, crown up/down/right)—the same orientations used in chronometer testing—so you can compare positional variance. Time Sync utility - See the current time adjusted by the atomic offset and re-sync whenever you like—useful for setting your collection precisely. Magnetism Check - Use your phone’s built-in magnetometer to watch the surrounding field (in μT). Set a baseline; values turn red when the field spikes beyond a safe threshold. Magnetized hairsprings often stick coils together, making a watch run fast—or even stop—so catching spikes early matters. Exports for your records - Share a crisp Accuracy Card (PDF/PNG) summarizing current rate and trend chart. - Export a CSV of all measurements for your personal logs or watchmaker. Why it helps - Clarity: SPD + charts make performance easy to understand and compare. - Context: Positions and comments reveal what really changes rate. - Confidence: Atomic-time reference reduces guesswork when setting or regulating. - Care: Magnetism is common in modern life (speakers, bags, gadgets); quick checks help you avoid surprises between services. Thoughtful by design - No account required. - Works offline after first sync (network only needed for reference time). - Fast, friendly, and built for everyday use. Whether you’re tracking a new diver, tuning a cherished vintage piece, or keeping a whole box on-spec, Watch Tracker gives you the tools to measure, understand, and enjoy your watches more.

Momentum comes from crawler snapshots for the tracked storefront. “Viral growth signal” means unusually fast recent rating gains; it is an indicator, not download data.
