After tracking finances in Google Sheets since 2016 (currently at column XE - 657 columns), I finally built the app my wife and I needed. The breaking point was yet another argument about a forgotten Amazon purchase that broke our budget. personifi is intentionally simple - real-time sync between partners, individual logins with shared data, and transaction entry that takes 12 seconds on mobile. Built with Next.js, .NET, and Postgres, running on a €4.55/month Hetzner VPS with Nomad orchestration. The most validating moment: my wife told me she actually prefers it to our spreadsheet. After 9 years of her tolerating my spreadsheet obsession, that's worth more than any metric. Currently at 2 DAU (us), but opening it up at £4.99/month for couples who want to stop arguing about money. Also included our free Google Sheets template if you prefer that route.
