Fred Espenak Collaborated With Me To Add A New Feature For 2024 Called Photographer's Mode (See Below)

I released the first concept of an eclipse "talking" timer in 2002 (Windows Pocket PC). I have helped people enjoy eclipses with better timing for 22 years! Featured in Sky and Telescope Magazine, 2002, 2003, 2017, and 2022.

Unique to my app is the Partial Phase Image Sequence Calculator. Using your final position contact times, this feature calculates 10 clock times equally spaced before and after totality. If you take a picture at each of these times you get a prefect set of partial phase images! Download my PPISC Worksheet to write down the times.
