SimpleRockets Goes Free, Shedding its Price Like Rockets During a Space Shuttle Launch

SimpleRockets has gone free for only the second time in the app's existence. Normally available in the $0.99-$2.99 range, now players can build rockets, trying to take off from various planets using realistic orbital physics based off of Johannes Kepler's laws of planetary motion. While the game does have in-app purchases, do not fret: they're all for rocket skins.

While rocket launches require careful planning, be quick with this one: it could go back to paid at any time.
