SurvKit

Everything you need. Even when nothing works anymore.

Blackout, flooding, no signal? That is exactly when you need knowledge and tools that work without the internet. SurvKit bundles first aid, emergency numbers for 20+ European countries, offline maps, crisis scenarios, a messenger that works without any mobile network, and an encrypted document vault - all fully usable offline.

No registration, no server, no cloud: all data stays on your device. The app only connects to the internet when you actively download optional content - such as offline map packages or Wikipedia articles for offline use.

SurvKit is under development - the App Store release will follow.

Features

  • First-aid guides (based on WHO/DRK/ERC), emergency numbers for 20+ EU countries, SOS tools
  • Offline maps (OpenStreetMap) with waypoints, track recording and GPX/KML export
  • No-network messenger: end-to-end encrypted chat via Bluetooth / Wi-Fi Direct
  • Encrypted document vault (AES-256) with legal-precaution templates
  • Supply planner based on official German BBK recommendations, checklists, emergency profile with wallet card
  • Knowledge library: scenarios, plants & mushrooms, knots, radio, tools, learning module for kids

Offline-First

Everything important is built in. Knowledge, map tools, calculators and guides work entirely without an internet connection - in airplane mode, and during a blackout.

Optional downloads such as offline map packages, Wikipedia articles or a local AI model are fetched once while you have a connection - after that they work offline too.

Privacy by Design

  • No account, no server, no cloud - all data stays locally on your device
  • No tracking - no analytics, advertising or crash-reporting SDKs
  • Encryption - vault with AES-256-GCM, messenger end-to-end (Curve25519 + ChaChaPoly)
  • Delete anytime - in the app or by uninstalling
