By comparison, Attaining Zen ($2) by Trileet is a distant second place.
Though it provides similar functionality, letting you place and resize stones, you’re given less control than in iZen Garden, and basically no control over the size or depth of your raking. The app is also silent.
But it does let you turn and discard rocks using interesting gestures, and it’s more reasonably priced than iZen Garden. With a little work, and particularly similar zen audio accompaniment, this could be a strong contender.
