## What is Survival Toolkit?

When the signal dies, your tools shouldn't.                                                            
                                                                                                         
  SurvivalToolKit is an offline-first survival kit for hikers, campers, and travelers. Every essential   
  feature works without internet — only the live weather card needs a connection.

  POWER SAVING                                                    
  As your battery drops, sensor frequency lowers automatically so essential tools stay available longer.

  • Saved routes and SOS coordinates stay on your phone.
