Tracklet
Personal Finance Tracker

Tracklet

  • My personal money babysitter — built because spreadsheets were judging me too hard.
  • Punch in daily expenses, get weekly + monthly reports, and see exactly where the chai money went. Spoiler: it's always chai.
  • Gmail integration auto-reads your transaction emails, lets you tag them with categories on the spot — don't have one? Create it right there, no excuses.
  • Credit & debit card tracking built in — link expenses to your cards and watch your "available balance" humble you in real time.
  • Heads up: still on a Google test account, so the Gmail magic is invite-only — ping me if you want in. The manual side is wide open, go wild.
