The Common Problem

Tired of awkward split chats and cluttered apps? You're not alone.

Most budgeting tools demand hours of manual categorization. Bill-splitting apps spam you with social feeds and ads. Hirro strips away the noise with a singular conviction: a note with a number on it.

Ads, tracking, or clutter

No promoted credit cards, no social feeds. Your private ledger is strictly yours.

How you spend and share your money is fundamentally how you live your life. It shouldn't feel like stressful bookkeeping, and splitting a shared dinner or holiday shouldn't create awkward tension between good friends. We built Hirro to give you pure clarity, calm design, and honest math without the clutter.

Simplicity by Architecture

Everything is a group. Built for real life.

A personal ledger is simply a group with one member. Adding someone converts it to a shared group. No separate "personal mode", no rigid boundaries.

Frequently Asked Questions

Everything you need to know about Hirro's architecture and features.

Splitwise focuses on social splitting but is bogged down by ads, paywalls, and complex multi-screen entry. YNAB focuses purely on zero-based personal budgeting. Hirro bridges both worlds under a unified philosophy: everything is a group. You get lightning 10-second personal tracking, frictionless bill splitting, and loan amortization without ads, clutter, or forced subscriptions.

Floating-point numbers in traditional software can introduce subtle rounding errors (e.g. $0.10 + $0.20 = $0.30000000000000004). Hirro stores every amount as an integer minor unit (cents, rials, etc.), guaranteeing that every split, settlement, and installment balances to the exact smallest currency unit without silent discrepancies.

Your financial records are private. Hirro does not sell user data, run third-party advertising trackers, or share your financial records with marketers. We operate on a calm, self-hosted, sovereign backend architecture.

Hirro was conceived and directed by Ali Azim (Product Owner & CEO), born out of personal frustration with noisy financial tools that cause more anxiety than they resolve. Hirro is crafted to be a quiet, dignified companion for your daily economic life.
