User reviews

Amazing in USA’24, but will it be available for Spain’26 ?

A little late, but… Simply put, this app single handily made my (and the fine folks in Detroit, TX) experience possible for the 2024 eclipse.
I thank Dustin at “SmarterEveryday” for turning me on to this.
Everyone around me thought I was some kind of genius/scientist as I was calling out the phases of the eclipse.
I think the most important feature was telling everyone when when to dawn their glasses again (after the 4m 15s of totality).

With that being said, I will be in Spain this summer. Will the app be updated to service it?

To everyone else. If you’re passionate in science, willing to learn the app (it’s not hard), this app is great. I knew I was in safe hands once the ‘call outs’ started. With the potential 1m 40s I’m going to experience this year, I’d like to feel that safe again.

Worked well for the April 2024 total solar eclipse

The UI is a bit barebones, but it gets the job done. The down-to-the second timing, when combined with custom limb correction, allowed me to capture Bailey’s beads at C2 and C3. 10/10 would use again.

Enhanced our eclipse experiences.

If you take the time to familiarize yourself with the app before the event it enhances your enjoyment of an eclipse. It lets you know when it’s safe to remove protective eyewear and reminds you to observe your surroundings and the horizon.

I would recommend turning off notifications after an event is over. I was in a slight panic today when my app started to give instructions. I realized the eclipse I purchased for last year must have had only the month and day in its programing so I assume it will be giving me instructions every April 8th. It did bring back welcome memories.

Worked Great !!!!

Used this for the 2024 USA Eclipse. Everything worked great. One year later, it’s alerting me again, so maybe it can’t tell what year it is. Not a big deal, gave me a reminder of what I was doing at this exact time last year. I do recommend, if you’re where it will be useful to observe an eclipse.

Great app, but…

I love the app!! But for a 2024 Eclipse… the app should NOT have woken up today in 2025 with April 8 2024 alerts!!
