## What is Watch Tracker?

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.

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.

I don’t see any reference time based on when I should perform the measurement to track the accuracy
