I kept lending money to friends and losing track of exactly how much, when, and whether interest was agreed on a notebook works until someone forgets to update it. So I built LendTracker, a free web app that:
Tracks what you lend or borrow, interest calculated automatically down to the day
Handles partial payments and renegotiated due dates without losing the original terms
Lets you share a read-only link so both sides see the same numbers
Sign in with Google, no spreadsheet required
Solo-built, still early genuinely looking for feedback, especially from anyone who's tried solving this same problem themselves. Link: LendTracker IOU Tracker for Money You Lend or Borrow
LendTracker tracks money you've lent or borrowed between friends and family, calculating interest automatically and keeping a full payment history.
LendTracker is a free web app for tracking informal loans between friends and family. Log what you lent or borrowed, and it calculates interest automatically, handles partial payments correctly (interest first, then principal), and keeps a full history — so nobody has to "just remember" who owes what. Sign in with Google, no spreadsheet required.
