This uses the algorithms developed over the past 150 years along with the best information available about the locations of sun, moon, and earth to predict when an eclipse will occur at a particular location on the earth. In addition the prediction parameters are updated for the latest predictions by IERS. This is useful to find where to go, where to look, and how the moon will move across the sun. It also provides the sunrise/set times for the location

Verdict
The clearest difference is price: EclipseTimesCalc at Free against Lunar Eclipse Guide's $1.99. EclipseTimesCalc also leads on in-app purchases (none vs 1) and ads (none vs shown). Lunar Eclipse Guide's advantage is iOS requirement (15.0 vs 26.0). On update cadence and device support there is nothing between them.
