9. The bowstring release of claim 1, wherein:

the bowstring release is selected from the group consisting of a trigger-based release device, a triggerless release device, and a back tension release device;

the bowstring is configured to produce a bowstring force acting toward a target;

the bowstring holder comprises a hook, the hook configured to hold the bowstring until the hook is pivoted, relative to the bowstring, to the release position to enable the bowstring to slide out of the hook due to the bowstring force; and

the hook and the safety device are configured to cooperate so that, as a result of the bowstring holder being disengaged from the sear;

the hook pivots until striking a portion of the safety device;

the portion of the safety device brings the hook to a stop at the intermediate position, preventing the hook from pivoting to the release position; and

the hook'"'"'s striking of the portion of the safety device causes the output, the output being selected from the group consisting of a sound and a vibration,

wherein the output is helpful in learning how to operate the bowstring release.

10. A bowstring release comprising:

a body;

a bowstring holder pivotally coupled to the body, the bowstring holder being pivotal from a first position associated with holding of a bowstring to a second position associated with releasing of the bowstring;

a sear supported by the body, the sear configured to restrain the bowstring holder in the first position until the bowstring holder is subject to a level of force; and

a safety member attachable to the body, the safety member being configured so that, when the bowstring holder is unrestrained by the sear;

(a) the bowstring holder moves from the first position to an intermediate position where the bowstring holder contacts the safety member; and

(b) the safety member prevents the bowstring holder from moving to the second position so as to prevent an unintentional release of the bowstring.

11. The bowstring release of claim 10, which comprises a hinge that pivotally couples the bowstring holder to the body, the hinge extending along an axis, the bowstring holder being pivotal about the axis.

12. The bowstring release of claim 11, wherein the safety member is configured to bring the bowstring holder to a stop at the intermediate position after the bowstring holder has traveled and generated a momentum, the bowstring holder striking the safety member so as to generate an output based on the momentum, the output facilitating training in use of the bowstring release.

13. The bowstring release of claim 12, wherein:

the bowstring is configured to produce a bowstring force acting toward a target; and

the bowstring holder comprises a hook, the hook configured to hold the bowstring until the hook is pivoted, relative to the bowstring, to the second position to enable the bowstring to slide out of the hook due to the bowstring force.

14. The bowstring release of claim 13, wherein the safety member comprises a safety pin.

15. The bowstring release of claim 14, wherein the bowstring release defines an opening configured to receive at least part of the safety member.

16. The bowstring release of claim 15, wherein the bowstring release comprises a safety lock configured to cooperate with the safety member.

17. The bowstring release of claim 16, wherein the body defines a safety member holder configured to hold the safety member when the safety member is not being used.

18. The bowstring release of claim 13, wherein the output is selected from the group consisting of:

(a) a tactile output; and

(b) an audible output.

19. The bowstring release of claim 10, wherein:

the bowstring release is selected from the group consisting of a trigger-based release device, a triggerless release device, and a back tension release device;

the bowstring is configured to produce a bowstring force acting toward a target;

the bowstring holder comprises a hook, the hook configured to hold the bowstring until the hook is pivoted, relative to the bowstring, to the second position to enable the bowstring to slide out of the hook due to the bowstring force; and

the hook and the safety member are configured to cooperate so that, as a result of the bowstring holder being unrestrained by the sear;

the hook pivots until striking the safety member;

the safety member brings the hook to a stop at the intermediate position, preventing the hook from pivoting to the second position; and

the hook'"'"'s striking of the safety member causes an output, the output being selected from the group consisting of a sound and a vibration,

wherein the output is helpful in learning how to operate the bowstring release.

20. A bowstring release comprising:

a body;

a sear supported by the body;

a bowstring holder pivotally coupled to the body, the bowstring holder being pivotal between;

(a) a non-release position in which the bowstring holder is positioned to hold a bowstring when the sear blocks movement of the bowstring holder; and
