## Review summary

Totality is widely praised as a free, ad-free, easy-to-use eclipse-planning tool with an impressive interactive map that shows your location relative to the path and provides timing details and Google Maps directions. It’s especially valued for planning travel and educational content. However, user feedback consistently notes stability issues after updates (crashes on launch and glitches), occasional problems locating the user on the map, and some timing inaccuracies. Most users report improvements after fixes and still recommend the app for eclipse viewing.

### Pros

- Easy to use and intuitive
- Interactive eclipse map with centerline/timing overlay
- Shows your current location and provides Google Maps directions to viewing spots

### Cons

- Problems locating your position on the map or map not showing location
- Timing data can be off by minutes or hours (Delta-T related or mispredictions)
- Updates can introduce glitches or instability
