DT Prep

An emergency-preparedness planner that works with no internet, ever. Build a plan for each scenario out of the sections it actually needs, keep your go-bags checked off, and hand the whole thing to someone else’s phone by QR code — no Wi-Fi, no signal, no account.

Served straight from my own server — no app store, no account, no tracking.

• Unlimited plans, one per scenario (house fire, hurricane, bug-out, anything), each tagged Evacuation, Shelter-in-Place, Severe Weather, Medical, Communication, or General and color-coded on the home screen
• 📻 PACE plan — Primary, Alternate, Contingency, and Emergency ways to communicate, shown as clear P/A/C/E cards
• 🚗 Evacuation plan — routes, destinations, what triggers leaving, and a meeting point with a real GPS pin
• 🏠 Shelter-in-place — gas, water, and electric shutoff locations, safe room, where supplies are cached
• 📇 Emergency contacts, 🩺 medical info (blood type, allergies, medications, conditions, doctor, insurance), and 📍 meeting points — repeatable lists
• 📝 Custom sections — name your own fields (text, notes, number, yes/no, GPS location)
• ⭐ Save any filled-in section — your family PACE plan, your usual contacts — as a default and drop it into other plans in one tap
• 👪 A reusable People roster: add someone once with their phone number, then pick them for any plan
• Every section opens read-only first, so checking a plan in a hurry can never change it by accident; editing is behind an explicit ✏️ tap
• Long-press and drag to reorder entries in any list

• 🎒 Seven built-in templates: General Bug-Out Bag, Severe Weather, Hurricane, Cold Weather, Wildfire, Vehicle Kit, and a one-day Mobile Comms bag built around a handheld radio
• Every template is yours to edit, duplicate, delete, or restore — or make your own, or save any checklist as a template
• Tap ➕ for a box of every piece of gear, grouped by category; tick what you want or type your own, and anything you type becomes a preset for every other list
• Items grouped by category (water, food, medical, tools, light & power, shelter & warmth, communication, and more) with live packed counts
• Set your household size (people and pets) once and quantities like “1 gal/person/day, 3-day minimum” are worked out for you
• Have / Need numbers flag what you’re short on; rotate-by dates flag expired items in red
• Weekly reminder for anything expired or expiring within 30 days (optional)
• Tap items off as you pack, move packed items to the bottom, and Reset to start fresh before the next trip or storm

• 🚨 Emergency view — one big-text screen per plan: where to meet, who to call (one tap opens the dialer), how to communicate, how to get out, utility shutoffs, and medical info
• 🧭 Distance and compass direction to any saved GPS pin (“2.3 mi, bearing 214° SW”) from GPS alone — no map download, no signal
• A home-screen widget showing your pinned plan’s meeting point and phone numbers at a glance
• Hand off to whatever maps app you have for turn-by-turn, when you have one

• 📤 Share a whole plan phone-to-phone by QR code — no Wi-Fi, no signal, no account; a big plan becomes a short auto-advancing sequence of codes the other phone’s camera reassembles
• Share checklist templates and gear presets the same way
• 💾 Back up everything to one file and restore it on any phone — restoring only adds, it never overwrites what’s already there
• 📄 Export any plan as a PDF to print as a paper backup
• ✅ Each plan shows when it was last reviewed and last shared, with an optional reminder every 90 days to look it over

• 📖 A built-in guide with search: First Aid, Water & Food, Fire & Warmth, Shelter, Signaling & Navigation, Communication, Sanitation & Hygiene, Evacuation & Travel, and Utilities & Hazards
• Short, scannable how-to topics written to be read on a small screen under stress — general knowledge, not a substitute for real training

• No internet permission at all — the app has nothing to talk to even if it wanted to. Your plans live only on your phone
• No account, no sign-up, no ads, no analytics
• Camera — only to scan a plan or template someone shares with you
• Location — only when you tap “use current location” or ask for distance and direction to a pin
• Notifications — only for the optional review and expiry reminders
• Start at boot — only to re-arm those reminders after your phone restarts

• Download the APK above on your phone, then install it — Android will ask you to allow “Install unknown apps” for your browser the first time
• Google Play Protect may warn that the app is from an unknown developer, or offer to scan it first. That’s expected for any app installed outside the Play Store — tap More details → Install anyway (or let it scan; it will pass). The app has no internet permission, so there’s nothing it could send even if it wanted to
• Open DT Prep — a short walkthrough runs the first time (replay it any time from the ❔ icon)
• Tap + to create your first plan, then add a PACE plan, evacuation plan, supply checklist, or whatever it needs
• Set your household size from the ⋮ menu on the home screen so checklist quantities are worked out for you
