### 5/5 — Nice summary of gravity events

Some formatting issues on event detail info at left sidebar.

### 5/5 — For alerts

*2020-02-22*

Nice app, very pretty. If you want to receive real time alerts also get the app Gravitational Wave Events.

### 3/5 — I love the content but the lack of push alerts almost defeats the purpose

*2020-02-06*

The layout in the app is wonderful. However there are no push alerts, which seems to me to defeat the purpose. Hopefully the developers can change this in an upcoming update and then it will truly become an instrument for the public

### 5/5 — Very intuitive interface

*2019-11-09*

This is a great and very easy to use app for keeping up to date with the latest gravitational wave events!
