MARS CLOCK NASA@VISWA MITHRA Excellent widget clock app

★★★★★ 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.

★★★★★ Kevin · Aug 17, 2012

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

★★★★★ A Google user · Jul 25, 2014

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.

★★★★★ sharon · Aug 8, 2012

Mars clock This is a cool little app! No problems on my Samsung Galaxy - old version. Thanks, Scott.

★☆☆☆☆ 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.
