Description

MarsClock is an alarm clock that lets you see times for all three of NASA's Mars rovers -- Spirit, Opportunity, and Curiosity -- as well as the InSight lander and the new Perseverance rover. You can also set alarms in Mars time, either as one-shot alarms or as alarms that will repeat every sol (that is, every Martian day).

This app is released for free by a (former) rover driver on NASA's Mars missions. Enjoy it!

Comments on MarsClock for Android

★★★★★ A. Karley · Jan 8, 2022

Fun but fundamentally completely useless. Which is fine, me not being a Mars rover driver. No adverts. I need to sample some Jeff Wayne/ War of the Worlds for alarm tones.

Remove menu button We don't need menu buttons anymore, put the menu button in top right corner

Mars is a world of wonders Great app. If only the time zone on my phone would one day be the same as Spirit or Oppy.

★☆☆☆☆ Kimberly · Aug 6, 2012

Ummmm... If I am looking at this correctly the times are how long each has been on Mars. At this time curiosity had been on Mars for just over an hour but app shows 19+ hours... Disappointed.
