User Reviews

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

Free to download and use; ad-free and privacy-conscious
Easy to use and intuitive
Interactive eclipse map with centerline/timing overlay
Shows your current location and provides Google Maps directions to viewing spots
Educational resources and classroom activities included

Cons

Crashes on launch or during use after updates
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
Some UI taps (e.g., tapping times) may fail or cause crashes

I’ve used it for two total solar eclipses now. It’s been an amazing tool.

Can you fix the bugs bc I can’t see the percent of the eclipse and the time

This app is essential when you are traveling for a solar eclipse. I recommended it to friends and coworkers to use and everyone really thought it was effective. Hopefully there can be an app developed for lunar eclipses too! Nicely done!
