What people are saying
"A few days ago I got a notification that there was earthquake activity near my brother's location. I called him right away — he's fine. But I knew before he even contacted us. This is why I built this app."

A Must-Have for Families Living Apart
"This app gives me peace of mind. Living in Canada while my family is in the Philippines, I appreciate being able to monitor their safety. It gives me comfort knowing I can stay informed and have one less thing to worry about."

Superb!
"I've been using TerraSentri for a while now and it's been really useful. What I like most is that I can save multiple locations, not just where I currently am, so I can also keep an eye on places where my family lives or works. The alerts are timely, the app is easy to navigate, and the information is presented in a way that's easy to understand. It's great to have earthquakes, typhoons, volcano updates, and other hazards in one app. Definitely worth downloading if you want to stay informed and be more prepared."

An App that cares
"Really enjoying TerraSentri so far! One of my favorite things is that it can be used internationally — a huge plus for anyone with loved ones living abroad. It gives me peace of mind knowing I can stay updated on my family, even when they're far away."
