Built for women and vulnerable individuals who need safety tools that work in real emergencies — not just on paper.
In India, 1 woman is assaulted every 15 minutes. Most safety apps require unlocking the phone, opening the app, and pressing a button. In a real emergency — that's 3 steps too many.
REPSHIELD reduces that to one shake.

"I built REPSHIELD because safety should not require 3 steps. One shake should be enough."
💡 Every feature in REPSHIELD exists because a real person needed it.
