1. An applicator for applying an on-skin sensor assembly to skin of a host, the applicator including an insertion assembly comprising:
an insertion member configured to insert a sensor into the skin of the host;
a first drive assembly having a first amount of stored energy; and
a second drive assembly having a second amount of stored energy,
wherein the first amount of stored energy is wound in a rotational direction about an axis, and wherein the first drive assembly is configured to convert a portion of the first amount of stored energy to a first linear force to drive the insertion member and the second drive assembly in a distal direction to an inserted position, and wherein the first drive assembly is configured to convert another portion of the first amount of stored energy to a second linear force to drive the insertion member and the second drive assembly in a proximal direction from the inserted position,
wherein the second drive assembly is configured to supplement the second linear force in driving the insertion member in the proximal direction from the inserted position, and
wherein the first drive assembly is configured to activate the second drive assembly while driving the insertion member in the proximal direction.
