Today's Free App of the Day is Orbital
A well reviewed game that is a shoot the asteroid kind of game with also strategic elements.
From the product page:
You must shoot orbs into a grid with your cannon. The orb you fired will expand until it touches a wall or another orb. Each orb contains the number ‘3’, which decreases by one every time it is hit. After 3 hits they explode and you earn a point. The game could be endless… There is just one condition: a shot orb must not touch the death line above the cannon! If it does, the game is over.
