CRASHPROOF – ACCIDENT DOCUMENTATION, MADE SIMPLE After an accident, it’s a lot to process. CrashProof helps you stay calm and organized by guiding you through collecting the details you may need later — date & time the accident occurred, photos, notes about the accident, custom notes per photo, voice recordings, and a step-by-step checklist — all stored privately on your device. All with the ability to export a shareable report for your insurance company, attorney, employer, or anyone who needs it when you’re ready. CrashProof was inspired by a real moment: my daughter was in a car accident and called me, shaken and unsure of what to do next. After that, I realized people needed a simple way to document a car accident and stay organized, so I built CrashProof to help you capture the details and evidence when things feel chaotic. ORGANIZED EVIDENCE COLLECTION • Record voice notes while details are fresh • Take or import photos, organized into buckets (Damage, Scene, VIN, License Plates, Documents, and more) • Text notes about the accident • Long-press any photo to add/edit/delete notes per photo • Built-in accident checklist, plus additional checklists that can be customized by you EMERGENCY CALLS • Quick-dial the emergency number you set (for example: 911, 112, 999) when your device has phone service or emergency calling is available • Optional trusted contact number for fast calling EXPORTS YOU CAN SHARE • Generate a PDF report with photos, notes, checklist items, and timestamps • Create an Evidence ZIP with original photos/audio, the PDF, and a written summary • Useful for sharing with insurance, an attorney, an employer, or anyone who needs the documentation PRIVACY & SECURITY • Optional passcode with Face ID / Touch ID (requires passcode) • Works offline • No ads, no tracking, no account required • Your data stays on your device unless you choose to share it IMPORTANT CrashProof is a documentation tool. It does NOT detect crashes, contact emergency responders automatically, or provide medical advice. In an emergency, call your local emergency number immediately (calling requires a compatible device and network availability).
