Self-heal (Prunella vulgaris, mint family, Lamiaceae) is a low creeping mint with pretty purple flowers. It spreads, so it can become an annoying weed if you want a lawn that is all grass. The flowers feed bees and butterflies, so it helps support the insect community, if you don't mind nongrasses in your lawn.
