ChronoKeep: Watch Collection

ChronoKeep is a calm, private home for your watch collection. It shows you which watch to wear today, which automatics have wound down, and every service, warranty, and insurance date — before it slips by. No account. No ads. No market-data noise. Your collection lives on your iPhone, and nowhere else. KNOW WHAT TO WEAR A gentle rotation suggests the piece that's waited longest, so every watch gets time on the wrist — not just your favorites. NEVER LET AN AUTOMATIC STOP ChronoKeep tracks each automatic's power reserve from the moment you last wore or wound it. See at a glance what's running low or already stopped, and wind it with a tap. STAY AHEAD OF EVERY DATE Service intervals, warranty expiries, and insurance renewals, gathered into one quiet "Coming Up" list. Optional reminders arrive before a date passes — never after. KEEP THE FULL SET Store the box, papers, warranty card, and receipt for each watch, privately, on your device. A clear "full set" status shows what's complete — the way collectors actually value a piece. INSURANCE-READY IN ONE TAP Generate a clean, elegant PDF for any watch — or your whole collection — with photos, values, references, and provenance. Perfect for insurers, appraisals, or your own records. TRACK ACCURACY Log daily rate by resting position and see whether a movement holds to COSC tolerance over time. PRIVATE BY DESIGN ChronoKeep has no accounts and no servers. Nothing is uploaded, sold, or shared. Your collection syncs privately across your own devices through iCloud — we can't see it, ever. A quiet, considered tool for people who love watches. Nothing more, nothing louder.
