Every communication tool you use requires the thing that just failed.
Cell towers need power. Wi-Fi needs power. Your smart home, your group chats, your emergency alerts. All of it dies with the grid.
Cell towers go silent
Backup batteries last 4-8 hours. After that, your phone is a flashlight with a dead signal.
Internet disappears
No Wi-Fi, no data, no cloud. WhatsApp, iMessage, email, all gone in an instant.
Neighbors become strangers
The people most likely to help you are 30 feet away. But you have no way to reach them.
Government alerts fail too
FEMA and Notify NYC depend on the same infrastructure. When it fails, official channels go dark with everything else.
Prepare now. Communicate during partial outages.
Set up your emergency network (before the crisis)
Add emergency contacts, join your neighborhood on GridVoice, take the readiness assessment. See how many neighbors are prepared. All of this happens while the grid is stable — that's the whole point.
PreparationWhen disaster strikes (and you have internet)
During a partial outage, if you have any internet connection — WiFi via generator, cellular data, mobile hotspot, or satellite — GridVoice springs into action. Your contacts are already in the system. Push notifications alert them instantly.
Crisis mode (internet available)Coordinate with your neighborhood
Share your status (safe, evacuated, sheltering, need help). Check on neighbors. Relay information through your prepared network. Fast, clear, reliable — because you set it up in advance.
Community coordinationThe only app designed for preparation + partial outage communication.
Other apps promise offline mesh. GridVoice combines honest internet-based communication with real preparation: assessment, contacts, neighborhood coordination — all set up in advance.

Internet powered. Preparation focused.
GridVoice is a web app. It requires an internet connection to function. The preparation happens in advance, when everything is working.
Works with WiFi, cellular data, or mobile hotspot
Any internet connection qualifies. WiFi from a generator, cellular data from your phone, hotspot from a friend, satellite internet — GridVoice works with all of these.
RequirementExcels during partial outages
Cell towers down but WiFi up? Power lost but you have a generator? GridVoice shines. Your contacts are ready, notifications fire instantly, coordination is seamless.
ScenarioCannot work with zero connectivity
If every path to the internet is down (no cell, no WiFi, no satellite, nothing), GridVoice cannot operate. No app can. That's why preparation before the crisis is non-negotiable.
LimitationQuestions about GridVoice and emergencies.
🌩️ Does GridVoice work during a hurricane?
Yes — as long as you have any internet connection. Cell towers have backup batteries, satellite internet exists, WiFi via generator works. The key: if your internet connection survives, GridVoice does. If all connectivity is destroyed, it doesn't. Set up your network before the storm.
📡 What if cell towers go down?
GridVoice doesn't depend on cell towers. Use WiFi instead. A generator, battery-backed WiFi router, or shared hotspot from anyone with internet works fine. During most partial outages, you'll have some internet available.
🔌 What if power is completely out?
You need power for WiFi or internet anyway. GridVoice doesn't change this. Consider a generator, power bank, or solar charger as part of your emergency kit. But if you're prepared (charged devices, backup power), GridVoice is ready when you are.
📱 Can I set up GridVoice on my phone?
GridVoice is a web app. Visit gridvoice.polsia.app on any browser. You can add it to your home screen for quick access. Works on iPhone, Android, or any device with a browser and internet connection.
🤝 What does my neighborhood see about me?
You control what you share. Your neighborhood sees your zip code and your status (safe, evacuated, sheltering, need help). Your phone number and personal details are only shared with confirmed emergency contacts.
💳 Do I need to pay?
GridVoice offers a free tier with basic emergency contacts and readiness assessment. The Full Emergency Kit ($49 one-time) unlocks unlimited contacts, neighborhood groups, and offline-ready features. No subscriptions.
⚠️ What if total collapse happens?
No app works when all connectivity is gone. That's a fact of physics, not a GridVoice weakness. That's why preparation is critical: set up your contacts and plan NOW so when disaster hits and you have any internet at all, you're ready. GridVoice isn't a magic bullet — it's a preparation tool.
NYC's grid is failing faster than ever.
The question isn't if the next major blackout happens — it's when. And whether your neighborhood is ready.
Set up your emergency network before the next disaster.
GridVoice isn't magic — it's preparation. When you set up your contacts, neighborhood, and plan before a crisis hits, you're ready when disaster strikes. If you have any internet connection during a partial outage, your network is already in place. That's the advantage.
