** Apple Design Award winner and iPad Game of the Year! ** Enter the Darwinian world of a galactic mote. To survive, absorb smaller organisms and grow—but beware of larger predators. Osmos features unique physics-based play, stellar graphics, and a hypnotic ambient soundtrack. Absorb or be absorbed! “The ultimate ambient experience” — Gizmodo “Beyond doubt, a work of genius" — GameAndPlayer.net THE CRUX: you must grow by absorbing smaller motes, but to propel yourself you must eject matter behind you, causing you to shrink. From this delicate balance, Osmos leads the player through floating playgrounds, competitive petri dishes, deep solar systems, and more. “Named as iPad Game of the Year for a reason, Osmos is a fantastic game.

Verdict
The clearest difference is price: Auralux at Free against Osmos's $3.99. Auralux also leads on update cadence (every 2 months vs every 7 months) and ratings volume (5.2K vs 892). Osmos's advantage is in-app purchases (none vs 12) and chart position (#41 vs unranked). On rating, review sentiment, ads and device support there is nothing between them.
