User reviews

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

I’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 it’s the already and I don’t know how to access it.

Perspective

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

Fun app

Fun and educational receiving real time alerts on gravitational waves coursing through our time and space.
