Lendbrary is the go-to app for keeping track of all the things you lend to or borrow from your friends, family, etc. Lendbrary helps you to know who has what and when you can expect it back. No more looking for your [insert precious item here] and realizing that [insert favorite cousin here] still has it and hasn't returned it! As a bonus, you can set Lendbrary up to remind people to return items so you don't have to have that awkward conversation.
