Stuck in front of an apartment building, scrolling through old messages for the door code? Padlok remembers every door code, gate code, intercom and floor for you — and shows them right when you arrive. THE CODE FINDS YOU Get close to an address and Padlok sends a notification with everything you need to get in: codes, intercom name, floor, and your notes. Just passing by? It quietly disappears. That's geofencing working for you, not watching you. And every address can set its own terms: the hours it may speak up, and the exact area that counts as arriving. No buzz from the office at the weekend, and a circle sized to the building instead of the street. EVERYTHING TO GET IN, ON ONE CARD - Door and gate codes, intercom, floor, and any access notes - Add addresses from Contacts, Maps, or a postal address - Grouped by town, so you can pull up one place at a time - Lock Screen and Home Screen widgets showing the nearest address - One-tap directions in your favorite maps app - On your wrist too, with the Apple Watch app SHARING YOUR GUESTS WILL LOVE Send an address with its codes as a secure link or a QR code. The code carries the address itself, so it scans with no signal on either side. Guests open it in the browser or an App Clip — no account, no install. Perfect for dinner parties, babysitters, and deliveries. PRIVATE BY DESIGN Door codes are secrets, and Padlok treats them that way: they stay in your own private iCloud, out of our reach, and every link you share is end-to-end encrypted, so nobody else can read it — not even us. No ads, no tracking, ever. MADE FOR EVERYONE Padlok speaks 26 languages, with full VoiceOver support, free app icon customization, and iCloud sync across all your devices. PADLOK PREMIUM Add as many addresses as you like for free — the three nearest stay open, notifications, sharing and widgets included. Premium unlocks: - Every address, not just the nearest three - Arrival notifications on as many as you like - The hours and the area each one announces you in - Custom colors, icons and door labels - Tags and filters, to find an address by context More info: https://padlok.app Terms of Service (EULA): https://padlok.app/terms/ Privacy Policy: https://padlok.app/privacy/
