Buying emergency supplies is just the first step. Staying prepared means knowing what you have, what’s missing, and when to restock. When does your drinking water expire? How much emergency food is left? How long have you had those spare batteries? Does everyone in your family have what they need? PrepNotify is an emergency supply tracker built for you. Organize your supplies, track quantities and expiration dates, and get timely reminders so your supplies are ready when you need them. ## Know What You Have Organize food, water, emergency supplies, and essentials for babies, older adults, and pets by category. Record quantities, photos, expiration dates, and more. Search and filter to check your stock faster. ## Know What to Use First Based on quantities and expiration dates, PrepNotify marks items as Expiring Soon, Out of stock, Good, or Expired. See what to use or replace first. With notifications enabled, the app schedules one-time expiration reminders when a valid reminder time is available. Items with no stock don’t receive reminders. ## Check Without Opening the App Use a Home Screen widget to check items that need attention and their expiration status at a glance. ## Prepare Your Way Everyone’s needs are different. Build a supply list that fits you or your household, from everyday essentials and emergency kits to items for babies, older adults, and pets. ## Your Supplies, Across Devices Your item data and photos stay on your device and sync through your private iCloud database across devices signed in to the same Apple Account, so you don’t have to start over. ## Your Data Stays Yours No ads. No cross-app tracking. We don’t store your item data or photos on our own servers. They stay on your devices and in your private iCloud database. PrepNotify — Don’t just think you’re prepared. Know what you have.

See your calendar, tasks and reminders the moment you lift your phone — no unlocking, no tapping. CapLock turns your lock screen wallpaper into a live, beautiful overview of your day. WHY CAPLOCK Widgets are small and need a tap. CapLock paints your schedule directly onto the wallpaper, so the whole picture is there at a glance: today's events, this week, your to-dos, and little reminders from the people you care about. WHAT YOU CAN PUT ON YOUR LOCK SCREEN • Today's agenda – upcoming events with times, colored by calendar • Week strip – seven days with event titles, a time grid, or a weekly list • Month grid – the whole month with event chips in every day • To-do list – the things you actually need to get done • Reminders – set by you, with a time, an icon and a repeat rule • Reminders from friends – friends can place a note on your lock screen, and you on theirs WORKS WITH EVERY CALENDAR CapLock reads the calendars already on your iPhone: iCloud, Google Calendar, Outlook / Microsoft 365 (including Teams meetings), Exchange, Lark, and any subscribed calendar. Pick exactly which calendars appear. MAKE IT YOURS • 11 block styles: transparent, frosted glass, paper notes, grid paper, pastel, iOS-style widget cards and more • Handwritten font, custom sizes and weights, per block • Drag every block anywhere on the wallpaper • Layout templates for a minimal, today, weekly or monthly look • Use your own photo or a built-in gradient background • Automatic light or dark text based on your photo ALWAYS UP TO DATE A one-time Shortcuts automation refreshes the wallpaper on a schedule, so the lock screen keeps up with your calendar even when the app is closed. FRIENDS ON YOUR LOCK SCREEN Sign in with Apple, choose a handle, add a friend by their handle. Reminders you send appear on their lock screen; theirs appear on yours. Only accepted friends can reach you, and there is no public search. PRIVACY FIRST Your calendar never leaves your device — the wallpaper is rendered on your iPhone. Only the to-dos and reminders you choose to share with friends are stored on our servers. CAPLOCK PRO Unlock every template and style, unlimited friends and more with a yearly or lifetime purchase. Payment is charged to your Apple ID account. Yearly subscriptions renew automatically unless cancelled at least 24 hours before the end of the period.
