Store listing

Full 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!

What's new

Updating for API level 36 per Google Play Store policies. Also, layout now avoids the notification bar, making it easier to press the overflow menu and to read the title bar.
