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 (https://emfollow.docs.ligo.org/userguide/). 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: https://gcn.gsfc.nasa.gov/lvc.html .)
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.

Ratings and Reviews
Universe calling!
That my iphone vibrates at the same time as astronomers around the world are being alerted is beyond cool.
I use the app almost daily to check which detectors are on line. I also use the seismometers to monitor world wide earthquakes. LIGO has some of the best to know when the earth is quiet enough for gravity wave science.
I think the communications on the app are mostly for professionals and simple questions will get referred to the excellent list of links. Sometimes a pro will answer questions not found in faqs, but it think it was not intended as a big public chat group. I thank the author for allowing the public a front row seat to the events and science going on.
Love this app to tracking the latest GW
I am not an astronomer but I use this app several times a day.
This app is easy to use.
Few more suggestions.
1. Should be okay to delete/hide event by swiping to the right. Like some email app.
2. Maybe mark different events by colors?
3. Add personalized filter to see a certain event like BNS only :)
Update on 1.9.1
Thanks for updating. Here are few more suggestions:
1. Add delete function to each event. And there should be no update once related event been deleted.
2. Maybe link user event comments to each related event.
For Professional and Amateur Astrophysicists
As an amateur astrophysicist this app has brought the science of gravitational wave detection to me. The real time alerts are exciting and with the links to more information, along with the ability to chat with others within the app, I have learned so much. This app makes the cutting edge science tangible and first person. LIGO’s entire Open Science commitment is incredible.
