Worn, or just owned? Mainplate is the private catalogue for your watch box: log every wear and see what each watch really costs you, keep box, papers, service history and value together, and let a shake pick today's watch. Flips and accuracy too. Synced with iCloud, no account needed. WEAR TRACKING & COST-PER-WEAR Log the days you actually wear each watch and Mainplate turns price into perspective: wear counts, cost-per-wear, and a Rotation card on the dashboard that shows what you really reach for, and what has been sitting in the box too long. YOUR COLLECTION, CATALOGUED Every watch you own on one clean page: brand, model, reference, year, box and papers, purchase price and current value. Keep the full service history and your notes with each piece, flag the watches you are still hunting on your wishlist, and mark what you have sold without losing its story. Built-in background removal cuts each watch photo out automatically, so your collection reads like a catalogue, not a camera roll. DAILY PICKER & WIDGET Can't decide? Shake your phone to reveal today's pick from your collection, mark it as worn, and keep it on your home screen with the Daily Pick widget. The pick syncs to every device you own. FLIPS: PROFIT & LOSS Follow each flip through its complete lifecycle: acquired, in progress, for sale, sold. Log every cost along the way (parts, service work, shipping, your own labour hours) and read net profit and ROI at a glance, for a single flip or across the whole register. Record full timegrapher sessions too: six-position rates, amplitude, beat error and delta, kept right beside the numbers they explain. ACCURACY, MEASURED How does your watch really run? The deviation tracker takes two readings days apart and computes the rate in seconds per day, plotted on a precision gauge against the COSC and METAS chronometer standards, with the complete measurement history of every watch. TIME SYNC A full-screen atomic-time reference clock for setting your watches to the second, with a locale-formatted date and a live moonphase display, including guidance for setting a moonphase complication correctly. DOCUMENT VAULT Keep warranty cards, receipts and service papers attached to the watch they belong to, preview them in place, and export everything together as a single, well-set PDF. SHARE YOUR COLLECTION Export your collection, or a single watch, as a clean, gallery-style image sized exactly for Instagram, TikTok, X, Facebook, Reddit or Pinterest, and post it through the system share sheet. EVERYWHERE YOU ARE Open Mainplate on iPhone, iPad or Mac and find the same collection, the same flips, the same history. iCloud keeps every device in step automatically. Nothing to configure, nothing to back up. ALSO IN MAINPLATE • Spare-parts inventory, generated automatically from your flip service logs • Per-watch PDF summary export, vault documents included • Service reminders, so no movement runs past its interval PRIVATE BY DESIGN Mainplate is standalone and single-user. There is no account, no sign-up, no tracking and no third-party servers: your data lives in your own iCloud and nowhere else. PLANS Free: up to 5 watches and 1 flip. Collector: unlimited collection and up to 5 flips. Pro: everything, unlimited. Lifetime: all Pro features, forever, with a single purchase. Subscriptions renew automatically unless cancelled at least 24 hours before the end of the current period. Manage or cancel anytime in your App Store account settings.
