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 Screenshots - [Screenshot 1](https://is1-ssl.mzstatic.com/image/thumb/Purple116/v4/eb/bb/33/ebbb33fe-4f02-1b84-40b8-3d48e66a2d6c/pr_source.png/1242x2688.png) - [Screenshot 2](https://is1-ssl.mzstatic.com/image/thumb/PurpleSource126/v4/13/cd/e5/13cde573-eb0d-7158-4fbc-c1a375b77b57/a3fe611a-b6d3-4035-8196-16292dade7bd_Simulator_Screenshot_-_iPhone_14_-_2023-04-04_at_17.20.26.png/1242x2688.png) - [Screenshot 3](https://is1-ssl.mzstatic.com/image/thumb/PurpleSource126/v4/a6/9a/cf/a69acf6f-539e-e685-83a4-cdddd8e22bee/ccc588fa-bb4b-47ad-9027-64e1f007bf89_Simulator_Screenshot_-_iPhone_14_-_2023-04-04_at_17.19.47.png/1242x2688.png) - [Screenshot 4](https://is1-ssl.mzstatic.com/image/thumb/Purple116/v4/11/2c/1f/112c1f2b-38c6-f403-b258-a47c9ffa36f7/pr_source.png/1242x2688.png) - [Screenshot 5](https://is1-ssl.mzstatic.com/image/thumb/Purple116/v4/3f/a2/d0/3fa2d08b-edea-1bd2-ddd9-613a305daa16/pr_source.png/1242x2688.png) - [Screenshot 6](https://is1-ssl.mzstatic.com/image/thumb/Purple116/v4/5a/c1/99/5ac19949-a353-4769-13fa-f38547e04b16/pr_source.png/1242x2688.png) - [Screenshot 7](https://is1-ssl.mzstatic.com/image/thumb/PurpleSource126/v4/8e/20/9f/8e209f62-f313-093c-1961-759e68fb3681/07f6cca1-7560-4b7b-a724-67c5f6bb849e_Simulator_Screenshot_-_iPhone_14_-_2023-04-04_at_17.23.34.png/1242x2688.png) ## Gravitational Wave Events Rating Breakdown in United States - 5 stars: 115 (87%) - 4 stars: 10 (8%) - 3 stars: 4 (3%) - 2 stars: 2 (2%) - 1 stars: 1 (1%) ## 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 [View all Gravitational Wave Events reviews and detailed analytics on AppTail](https://apptail.io/account/signup?utm_campaign=ai-crawl&utm_content=reviews) ## Apps Similar to Gravitational Wave Events - [Quantum Mechanics - Theories](https://apptail.io/app/quantum-mechanics-theories-vnk/united-states) - [Loughborough Wave Lab](https://apptail.io/app/loughborough-wave-lab-brDe/united-states) - [Astro-COLIBRI](https://apptail.io/app/astro-colibri-Qddg/united-states) - [PHENOM UFO](https://apptail.io/app/phenom-ufo-ziSn/united-states) - [Black hole finder](https://apptail.io/app/black-hole-finder-Vooo/united-states) - [Make Chirps](https://apptail.io/app/make-chirps-YsRp/united-states) - [Entangled.org](https://apptail.io/app/entangledorg-YyKq/united-states) - [VEREVIO - ESP & Remote Viewing](https://apptail.io/app/verevio-esp-remote-viewing-dFVq/united-states) - [Black Hole Vision](https://apptail.io/app/black-hole-vision-fIfu/united-states) - [Above Us: UAP Sighting Tracker](https://apptail.io/app/above-us-uap-sighting-tracker-IVyu/united-states) ## Gravitational Wave Events Available In - [United States](https://apptail.io/app/gravitational-wave-events-Zscg/united-states) - [United Kingdom](https://apptail.io/app/gravitational-wave-events-Zscg/united-kingdom) - [Italy](https://apptail.io/app/gravitational-wave-events-Zscg/italy) - [Canada](https://apptail.io/app/gravitational-wave-events-Zscg/canada) - [Australia](https://apptail.io/app/gravitational-wave-events-Zscg/australia) - [France](https://apptail.io/app/gravitational-wave-events-Zscg/france) - [Germany](https://apptail.io/app/gravitational-wave-events-Zscg/germany) - [Spain](https://apptail.io/app/gravitational-wave-events-Zscg/spain) - [Switzerland](https://apptail.io/app/gravitational-wave-events-Zscg/switzerland) - [Israel](https://apptail.io/app/gravitational-wave-events-Zscg/israel) - [Poland](https://apptail.io/app/gravitational-wave-events-Zscg/poland) - [India](https://apptail.io/app/gravitational-wave-events-Zscg/india) - [Belgium](https://apptail.io/app/gravitational-wave-events-Zscg/belgium) - [New Zealand](https://apptail.io/app/gravitational-wave-events-Zscg/new-zealand) - [Finland](https://apptail.io/app/gravitational-wave-events-Zscg/finland) - [Brazil](https://apptail.io/app/gravitational-wave-events-Zscg/brazil) - [Taiwan](https://apptail.io/app/gravitational-wave-events-Zscg/taiwan) - [Denmark](https://apptail.io/app/gravitational-wave-events-Zscg/denmark) - [South Korea](https://apptail.io/app/gravitational-wave-events-Zscg/south-korea) - [Greece](https://apptail.io/app/gravitational-wave-events-Zscg/greece) - [Ireland](https://apptail.io/app/gravitational-wave-events-Zscg/ireland) - [Hungary](https://apptail.io/app/gravitational-wave-events-Zscg/hungary) - [Czechia](https://apptail.io/app/gravitational-wave-events-Zscg/czechia) - [Norway](https://apptail.io/app/gravitational-wave-events-Zscg/norway) - [Mexico](https://apptail.io/app/gravitational-wave-events-Zscg/mexico) - [South Africa](https://apptail.io/app/gravitational-wave-events-Zscg/south-africa) - [Chile](https://apptail.io/app/gravitational-wave-events-Zscg/chile) - [Colombia](https://apptail.io/app/gravitational-wave-events-Zscg/colombia) - [Algeria](https://apptail.io/app/gravitational-wave-events-Zscg/algeria) - [Ecuador](https://apptail.io/app/gravitational-wave-events-Zscg/ecuador) - [Estonia](https://apptail.io/app/gravitational-wave-events-Zscg/estonia) - [Egypt](https://apptail.io/app/gravitational-wave-events-Zscg/egypt) - [Hong Kong SAR China](https://apptail.io/app/gravitational-wave-events-Zscg/hong-kong) - [Indonesia](https://apptail.io/app/gravitational-wave-events-Zscg/indonesia) - [Japan](https://apptail.io/app/gravitational-wave-events-Zscg/japan) - [Kuwait](https://apptail.io/app/gravitational-wave-events-Zscg/kuwait) - [Lebanon](https://apptail.io/app/gravitational-wave-events-Zscg/lebanon) - [Peru](https://apptail.io/app/gravitational-wave-events-Zscg/peru) - [Philippines](https://apptail.io/app/gravitational-wave-events-Zscg/philippines) - [Sweden](https://apptail.io/app/gravitational-wave-events-Zscg/sweden) - [Thailand](https://apptail.io/app/gravitational-wave-events-Zscg/thailand) - [Tunisia](https://apptail.io/app/gravitational-wave-events-Zscg/tunisia) - [Türkiye](https://apptail.io/app/gravitational-wave-events-Zscg/turkey) - [Vietnam](https://apptail.io/app/gravitational-wave-events-Zscg/vietnam) - [United Arab Emirates](https://apptail.io/app/gravitational-wave-events-Zscg/united-arab-emirates) --- ## About AppTail [AppTail](https://apptail.io) is a mobile app intelligence platform providing app analytics, ASO (App Store Optimization) tools, keyword tracking, competitor analysis, revenue estimates, and review monitoring for iOS App Store apps.
