About

Expify keeps your important documents safe on your device and reminds you before they expire — so you never miss a renewal again. Passport, driver's license, ID card, car inspection, insurance policies, warranties, visas, lease agreements, fire extinguishers… Everything with an expiry date, in one place. HOW IT WORKS • Scan with the camera: Take a photo and Expify recognizes the document type and its expiry date automatically. • Add from Files: Pick a PDF or a photo; digital policies and e-invoices are read directly. • Enter manually: For dates without a document (anniversaries, birthdays, lease end) — a few taps and it's tracked. • Confirm: Nothing is saved until you check it; dates, types and details can always be edited. REMINDERS THAT ARRIVE ON TIME • Timing set by document type: 6 months ahead for passports, 2 months for car inspections, the last month for warranties. • Choose your own reminder days for any document. • Tap "Handled it" on a notification to silence its reminders; yearly dates roll over to next year automatically. WHERE YOUR DOCUMENTS LIVE • Search by name, type or content — even a policy number inside the document. • Home Screen widget with your nearest expiry dates. • Spotlight: find any document straight from your device's search. • Export a single document as PDF or all your documents as a ZIP, optionally password-protected. Always free. PRIVACY FIRST Expify does all processing on your device. Your documents, their images and the text inside them never reach our servers; if you turn on sync, they are backed up only to your own iCloud account. No ads, no analytics SDK, no account required. EXPIFY PREMIUM Add unlimited documents, organize them into folders and sync them across your devices through your own iCloud account. Available as a monthly or yearly subscription, or a one-time lifetime purchase.
