Tally's overview screen — this month's committed spend, upcoming bills, net worth, and a spending breakdown, on a real household record

Key Features & Outcomes

  • Every number has a trail — no total exists without the real record behind it, reconciled against actual bank statements rather than self-reported entries
  • A real public explainer page, not just a sign-in wall — most of what's in this portfolio entry came straight from Tally's own /about page
  • Invite-only by design — no open signup, no advertising, built for one household's real money rather than as a general product

The idea

Every household's money moves through the same handful of things — bills, income, accounts, transfers — but rarely lives in one place anyone can actually check. Tally brings all of it into a single household ledger and reconciles it against real bank statements, so a number on screen always has a real record behind it.

The build

Editorial, light-mode, and unapologetically calm for a finance app — no dashboards trying to look busy. A real explainer page at /about (hero, feature callouts, an actual screenshot of the app) sits in front of the invite-only sign-in, so anyone who lands on the site — not just an invited household member — understands what it is before being asked to sign in.

Why it matters

Built for one household's real finances, not as a general SaaS product — invite-only, no open signup, no advertising. The constraint that shaped it most: every figure needs a trail back to a real bill, transfer or bank statement line, not a number someone typed in and forgot to check.
