Planning your next trip to Mars and need help keeping time? Need up to date weather reports for the Red Planet? Need to know coordinates for space junk on Mars so you can salvage it for scrap? Mars Watch has all of this information and slightly more in a mildly interesting but ultimately pointless app. Marvel for literally seconds at the myriad ways research missions to Mars have failed. Ponder for mere milliseconds over wether you have enough warm clothes to survive the significantly sub-zero temperature highs. Speculate about why the developer feels this is a valuable use of his time.

It died because of dust accumulated on the solar panels preventing from getting the needed power, right? I came in with high expectations, and don’t get me wrong it deserves the five star review, but it feels outdated. ### 2/5 — Nice but not accurate *2025-01-20, version 2.2.0* The insight lander has been dead for 3 yrs now, should be updated… otherwise fine. ### 3/5 — App modification *2024-09-26, version 2.2.0* It would be great if could see a wide view of the planet itself, not just the landers. ### 5/5 — Great app *2024-07-30* I am a real space geek so this app sends to be made for people like me ### 5/5 — Great mars clock *2024-04-25* This is a great mars clock and even has info on the time on mars and the different rovers. I did some research and this is perfectly calibrated to actual mars time. ### 4/5 — Yay for Mars *2023-11-03* What your iPad was made for. ### 5/5 — Great app! *2023-07-06* A lot of info for those wanting to learn more about the Mars probes as well as info about Mars! Very intuitive and fun to use! ### 5/5 — I am new but happy *2023-04-19, version 2.2.0* Nice informative and stunning photos ### 5/5 — Cool View of Mars at a Glance *2023-01-01* I was fascinated by the real time updates of weather and current mission details on the red planet. The history lesson of “Dead probes” (past missions) was also interesting to see how far we have come in exploration. A generous prediction would be a handful of the best of humankind visits Mars in the next 50 years. Until that time, this app helps make Mars not so out of reach. ### 4/5 — Cool app *2022-09-25* This is kind of a dumb and pointless app, but for space lovers like myself, I actually kind of like this app as it kind of reminds me of wwv which is a station here on earth that gives the time in utc. You could say that this app is like WWV in that it gives a form of UTC but for the red planet. I also find it neat that you can even get the local Martian weather too. Lol. ## Frequently asked questions about Mars Watch ### What does the Mars Watch app do? The Mars Watch app provides current time and weather information for Mars.
