What's New in Gravitational Wave Events

2.2.2

June 29, 2026

Updated for visual features of iOS26.

User reviews

For the layman too

Itโ€™s a very interesting app that also color codes for gravitational wave events of interest , and has a little thingy to actually point to the sky were the signal is coming from. Makes you wonder.

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

it will never make waves

Iโ€™m disappointed

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 itโ€™s the already and I donโ€™t know how to access it.

Perspective

Thereโ€™s nothing like the news of a cataclysmic collision in deep space to put all earthly concerns into perspective.
