Título provisional: Tarsi-style copycat for Brazil and Spanish-speaking LatAm (working name)

Resumen

BriefingAutodeclarado

Tarsi (Bryl Lim, Philippines) lets users log spending, track balances across cards and accounts and plan bills with no account and no server, on iPhone and Android. A May 23 2026 podcast showed an App Store Connect dashboard with about $20K in the first month (Self-reported, screenshot).…

Launch is roughly Apr 2026 (inferred), so about 6 months: right at the POP 5.3 edge and flagged. Customers came from word of mouth, social and App Store search. HBV angle: a LatAm version with Pix/boleto categories and a mascot-led, privacy-first positioning, entered through ASO and SEO. Saturated category; weakest of today's existing entries.

Jobs to be done

When my spending is spread across Pix and several cards, I want a private tracker that logs entries from receipts, so I can know where my money goes without sharing bank logins.

HXC

Marcos · 31 · São Paulo: Uses Pix for everything, loses track of spending across cards. Frustration & buying signal: Wants a private, simple tracker that reads Pix receipts; would pay a small yearly fee.
