Mars Watch is an iPhone app developed by Matthew Flint that falls under the category of Education & Reference. This free app aims to provide users with information about Mars, including accurate time calculations for Mars Coordinated Time, recent weather reports from the Curiosity rover, images of Mars research probes, and details on past and present research projects. It also offers accurate time calculations for each probe's location.

While Mars Watch may initially pique your curiosity, it quickly becomes apparent that the app offers little real value. The information provided is mildly interesting, but ultimately pointless. Users can marvel for a few seconds at the various ways research missions to Mars have failed, ponder for mere milliseconds over the sub-zero temperature highs, and speculate about the developer's motivation for creating such an app.

Overall, Mars Watch receives mixed reviews from users. Some praise its simplicity and the fact that it does what it's supposed to do. However, others find it not very useful or question why it receives high ratings. One user even suggests that the app is not annoying, which could be seen as a backhanded compliment.

If you're planning a trip to Mars or simply have a passing interest in the Red Planet, Mars Watch may provide a brief moment of entertainment. However, if you're seeking a truly informative and useful app, you may want to look elsewhere.
