How well can you judge an angle? Duometry challenges you to match a target angle as closely as you can. Fold a compatible device or adjust the on-screen dial, lock in your guess, and discover how close you came. Play solo over 5 or 10 rounds and aim for your best score. Pass one device between 2–8 players for a friendly competition. Everyone’s guesses stay hidden until the shared reveal. Find out who came closest, compare scores, and keep playing.

Volley Heads's advantage is price ($0.99 vs $2.99) and device support (3 vs 1). On ads and in-app purchases there is nothing between them.
