## Gravitational Wave Events Description
Receive alerts of Gravitational Wave Events from the LIGO/Virgo/KAGRA Collaboration (LVK) on your iPhone.

This is an app for both the LIGO/Virgo/KAGRA Community and the general public.  It provides low latency alerts using the Open Public Alerts currently being deployed by the Gamma-ray Coordinates Network (GCN) through GCN/LVK Notices (  To receive alerts using the app just select the category of alerts you wish to receive - it's that simple!  

The O3 observing run ended in March 2020.  O4 is expected to start in May 2023.  The app will download all O4 events and counterparts as they are reported through a GCN Notice in addition to any related GCN Circulars.  The app database is  pre-populated with selected Notices and Circulars from all previous O1, O2 and O3 events.  The app retains Notices for one Mock Event reported through GCN for testing purposes.  (For information on LIGO/Virgo/KAGRA Collaboration GCN Notices see:  .)

Includes an interactive sky map showing the location of each event.

The app also has a public Message exchange bulletin board and some interesting Links.  The Links provide information on Gravitational Waves and the LIGO and Virgo observatories.

## Gravitational Wave Events Reviews in United States

### ***** "So much fun and learning"
As a family we are enjoying this app.  We will run across an event and that will bring up other questions so we end up learning something every time
-- Carebear5101, 2026-02-21

### ***** "Useful tool"
Been using it for years. Very nice. One suggestion: it would be good if the database could be searched (e.g., show all Vera Rubin circulars). Maybe it’s the already and I don’t know how to access it.
-- nova watcher, 2026-01-07

### ***** "Fun app"
Fun and educational receiving real time alerts on gravitational waves coursing through our time and space.
-- SeattleWadwo, 2025-10-27

### ***** "Gravitational waves app"
This is in fact the coolest thing ever!!! I hope you enjoy it as much as I do!
-- Brian’s iPhone 16 plus, 2025-08-20

### ***** "New Science at its best"
Exciting & field breaking gravitational wave detection will become the new telemetry as did all the other scopes.  LISA funding is more important than ever, just saying!
-- Alaskadotnet, 2025-06-29

### ***** "Best Way to See Black Holes"
…is to hear them!
-- Maybe Wavey Davey, 2025-06-10

### ***** "The ultimate linked in…"
Straight up top-drawer info source for real time data detailing actual warps in the space we inhabit, all around us, as immersed as it gets.

(There; feel that? Maybe just a fraction of the diameter of a proton, but it’s the real thing. Some fun, eh?)

Einstein would be tickled pink…
-- StabileT, 2025-03-16

### ***** "Fun"
Toured Hanford and was amazed by the technology. Then I asked “where’s the indication that the detector saw something” and was astonished when told that the facility had no such readout. Looking back I’m guessing everyone there had this app on their phone. Great work and thank you for sharing!
-- NTOx2, 2025-02-06

### **--- "Inscrutable"
Unless one is involved w LIGO there’s little useful info presented to a civilian.
-- PJMD2, 2025-02-04

### *---- "I am so offended."
I got banned for saying three things that were “not relevant.” I did not cuss or say anything inappropriate. I deeply respect science.
-- TrainLover5000, 2025-01-04

### ***** "Best app for gravity waves"
If knowing what cataclysmic events happened billions of years ago is interesting, this is where the information and the alerts are.
-- Asymptotic freedom, 2024-11-10

### ***** "GW.  Learning new astronomy"
What a great way to learn about gravity waves.  Love the app.
-- WX Nomad, 2024-09-19

### ***** "Review"
As a medical scientist as opposed to a physical scientist I feel privileged to be allowed access to this information. I am learning a lot and hope to continue to increase my literacy on the science of gravitational wave events. Thank you for making this available.
-- IBF3rd, 2024-09-09

### ***** "Real Time Notification of Gravitational Wave Detections!"
Love that anyone can receive alerts of gravitational wave detections.  I even love the special chirp sound.  The discussion section is great to get good recommendations of new publications and papers.   Thank you for helping non-gravitational experts learn more about this fascinating field.
-- Chelsey650, 2024-09-03

### ***** "Great App for Gravity Waves"
If you want access to messages that the professionals use to discuss what is going on this is the app for you. You will get an alert 20 seconds after an event happens. Excellent interface too.
-- idonotwanttohaveanickname, 2024-05-18

### ***** "Great way to experience GW Astronomy"
This app provides realtime alerts and reporting from around the world on the emerging field of Gravitational Wave Astronomy. It allows one to filter on and receive notifications for event types of interest. I enjoy getting notifications every few days on some new event or observations. Especially fascinating are events involving neutron stars, since they are the most likely to have remnants that can be observed by other means. I have read practically every report by teams trying to correlate observations of neutron star events, and am always amazed by the different teams of astronomers working together to understand the nature of the universe. This app is perfect for anyone who wishes to experience real-time and understand this emerging field and technology better.
-- Sparqx2, 2024-05-13

### ****- "Fascinating GW App"
It’s hard to believe you can get instant notifications on gravitational wave events on your personal smartphone. That we can detect them at all is a miracle of modern science. 

I must admit however that much of the info presented in this app is technical and over my head, with numerous acronyms I don’t understand and technical data given that I cannot interpret. Thus, the app could be improved if there were significant descriptions and background info on GW events, the various detectors, the info presented, etc. Photos of the detectors for example and graphics would be super helpful. 

Thanks,
B
-- rigpasword, 2024-04-29

### ***** "The steady rumble of the universe"
Like distant continuous crackling thunder LIGO leves me in in stunned amazement of the immensity of the cosmos. 

Like any background radiation you keep thinking there could be a pattern and just get hypnotized by the static. 

As a kid in the 60s watching Trek, I never imagined that we would actually someday hear this.

Still in Awe. ✨
-- jill1776, 2024-01-20

### ***** "Love it. Hope you add more features"
Would love to be able to playback the real sound and see the frequency wave
-- Mr rap123, 2023-08-02

### ***** "SCIENCE!"
Undergrad physics student here working in the field - It's amazing how much more sensitive LIGO has become compared to the already impressive handful of events per year in O2, and it's delightful to get these notifications multiple times a week. Very fun!
