Watch Tracker vs Backbeat Timegrapher

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.

Is your mechanical watch running fast? Slow? Perfectly on time? Backbeat gives you the answer in seconds — using nothing but your iPhone's built-in microphone. No clips taped to the case. No pressing the phone against the crown. No external mic dangling off the side. Just set your watch near your phone and get professional-grade timing data in real time. WHAT MAKES BACKBEAT DIFFERENT Other timegrapher apps force you to press your phone directly against the watch crown or attach an external microphone to pick up the tick. Backbeat doesn't. Its audio engine is built to detect and lock onto mechanical watch ticks at a distance, filtering out ambient noise and isolating the signal — so you get clean, reliable readings without awkward setups or extra hardware. PROFESSIONAL-GRADE METRICS Backbeat measures the three numbers that matter: - Rate — how many seconds per day your watch is gaining or losing - Beat error — how symmetrical your balance wheel's swing is - Amplitude — how far your balance wheel rotates with each oscillation These are the same measurements a $200+ bench timegrapher gives you — right on your phone. ZERO SETUP Place your watch near the phone. That's it. Backbeat automatically detects tick sounds, filters background noise, locks onto the beat, and delivers full timing metrics — all in real time. No calibration. No configuration. No learning curve. BUILT FOR WATCH PEOPLE Whether you're checking a vintage pickup before buying, verifying your regulation after a movement service, or just curious how your daily wearer is performing — Backbeat gives you the data you need in seconds. Perfect for collectors, hobbyists, modders, DIY regulators, and working watchmakers alike. WHY PAY FOR A BENCH TIMEGRAPHER? A dedicated timing machine costs $200 or more and sits on your workbench. Backbeat goes wherever your phone goes. Quick-check a watch at a flea market. Test a fresh regulation at your desk. Compare positions before bed. No gear to pack, no equipment to maintain.
