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.

Its cute but I have no idea what all that stuff means. 5 stars anyway because you put a lot of work into it and Im sure a lot of people does understand all that stuff. 😎

Great app. If only the time zone on my phone would one day be the same as Spirit or Oppy.
