Ever wonder if your favorite automatic watch is running a little fast, or if that vintage piece you just picked up needs a service? AccuBeat turns your iPhone into a fully functional mechanical watch timegrapher, right in your pocket. Whether you're a seasoned watchmaker, an avid Seiko modder, or a collector who just wants to keep tabs on your timepieces, we’ve made measuring watch accuracy as simple and accessible as possible. There is no need to shell out for clunky, expensive diagnostic machinery. AccuBeat uses your device's built-in microphone to listen to the literal heartbeat of your watch. Want to take your bench setup to the next level? AccuBeat works seamlessly with external piezo microphones, especially those affordable watch timegraphers you can easily pick up on AliExpress. Just plug one in, and you instantly have a pro-level regulation tool right on your desk! Key Features to Keep Your Collection Ticking: Your Pocket Watch Timegrapher: Instantly measure the daily rate (seconds per day) and beat error (ms) of your mechanical and automatic watches. Smart Auto-Detection: Not sure what frequency your watch runs at? The app automatically listens and detects the correct Beats Per Hour (BPH), supporting everything from vintage 14,400 BPH slow-beats to modern 28,800 BPH hi-beat movements. Track Your Watch Collection: Save your readings in the Recordings log. Compare how your timepiece performs over time, or check if your recent regulation finally got it running to COSC standards. Simple, Visual Diagnostics: You don't need to be a professional watchmaker to understand the data. Easy-to-read dials let you know instantly if your accuracy is "Poor," "Fair," or spot-on.
