Wrist Wallet

Get to know your mechanical watches, one observation at a time. Keep a personal wallet for every watch: photos, reference and movement details, purchase dates, serial numbers, service history and documents. Add acquisition price, currency, your own resale estimate, ownership status and warranty expiry. Values are entered by you, not automatic market valuations. Scan the front and back of a service card, or choose existing photos. On-device text recognition suggests possible serial numbers for you to check before saving. Search by name, reference or serial number, and choose photo cards or a compact collection view. See the latest service, listening session and everyday accuracy check at a glance. Compare your watch with the same reference clock, record the difference and check again later. An optional local reminder can prompt you in 24 hours. Manual time checks do not need a quiet room or microphone access. Listen with your iPhone microphone to explore a watch's beat rhythm. Choose one or two minutes independently of saving audio, with an optional placement countdown. When the audio passes consistency checks and the movement's beat rate is confirmed, Wrist Wallet can show an estimated gain or loss in seconds per day. Unreliable or conflicting timing is withheld. Choose to retain a recording, play it back, move through it or listen to the section supporting an estimate when available. Analyse saved audio again while preserving the original result. Listening history stays separate from dealer and watchmaker service records, with filters and favourites to help find sessions. Choose which details to include in a watch passport PDF. Export a collection file with optional audio, preview an import and keep existing matching records by default. Dark appearance follows your iPhone, and unfinished edits receive a confirmation before discarding. Watch storage, audio processing and card-text recognition run on your iPhone. No account is required. Microphone estimates are uncalibrated and depend on placement and background sound; they do not replace a calibrated timegrapher or professional servicing equipment. Beat error and amplitude measurements are not available. Wrist Wallet is free to use, supported by muted banner ads in Discover. Ads stay out of your watch collection, listening and saved-session screens. We request non-personalised ads and apply Google's restricted data processing setting. These settings limit data use; advertising services still process device identifiers, approximate location, ad interactions and diagnostics. Watch records, photos, service documents and recordings are never supplied to the advertising service. Where required, Google's consent screen offers consent, refusal and detailed choices. Available advertising privacy choices can be reopened in Settings. All watch features remain usable if you refuse consent or ads are unavailable. Allowing additional choices in Google's standard form does not enable personalised ad requests in Wrist Wallet.
