WhatDoIO

What is WhatDoIO? WhatDoIO is a fast, privacy-focused group expense tracking and bill-splitting platform built for travelers, roommates, couples, and friends.

Designed around a user-centric model, financial transparency, and offline resilience, WhatDoIO cuts out group clutter and makes tracking shared costs effortless:

Key Features: • User-Centric Privacy: You only see balances, credits, and debts that directly involve you. Interpersonal debts between other members remain strictly private, and personal solo expenses can be logged privately without cluttering the group feed or skewing shared balances. • No Countdown Delays or Daily Limits: Add expenses freely whenever you need them. No artificial wait timers, daily transaction caps, or paywalls blocking your core bill splitting. • Drop-Proof Offline Queueing: Never lose a transaction to spotty cell service. Keep logging expenses seamlessly through dead zones, subway tunnels, or basement venues—edits queue locally during your active session and sync automatically the moment you reconnect. • Two-Party Settlement Verification: Settlements move through a transparent lifecycle (Sent ➔ Acknowledged ➔ Confirmed). Debts are only cleared when the recipient actually confirms the funds arrived safely. • Daily Rate Currency Freeze: When traveling internationally, foreign expenses lock to the daily exchange rate on the day of purchase, protecting everyone from currency market fluctuations after the trip. • Single-Currency Direct Pass-Through: If all group members share the same home currency (e.g. CAD, EUR, GBP), intermediate conversions are completely bypassed for 100% penny precision with zero rounding drift. • Instant 6-Character Group Join: Friends join ledgers in seconds with a simple 6-character code—no tedious surveys or complicated onboarding.
