Starbase Chill is a starbase simulation, where there is much to do, but no particular urgency. You are free to focus on what interests you: the starbase itself, or distant planets. The starbase has many interrelated systems to manage. Outside, there is a large three-dimensional space to explore. For context: * Starbase Chill is at peace. That is, no enemy is coming to attack us. * Things happen at a leisurely pace. * There is no overall score, or any set victory conditions. * As part of Starbase Chill's commitment to a low-stress environment, there are no alerts or notifications. This is a single-device, offline app. There are no networking calls, and no data is collected by the app. The app is completely usable on a narrow or iPhone screen; but it can be a nicer experience on a wider screen, if that's an option. Enjoy your time on Starbase Chill!

Starbase Chill's advantage is ads (none vs shown) and update cadence (every 2 days vs every 8 months). On price and device support there is nothing between them.
