About this app
Tired of group apps broadcasting your private spending?
WhatDoIO is a private, viewer-centric bill splitter and group expense tracker designed to end awkward oversharing. Unlike traditional expense splitters that broadcast every purchase and interpersonal debt to the entire group, WhatDoIO keeps your shared expenses and peer debts strictly confidential.
Whether you need to split bills with roommates, share vacation expenses on group trips, or track daily shared costs with friends, you only see the expenses and balances that directly involve you. No clutter, no drama—just what do I owe?
Why WhatDoIO is Built Different:
• Viewer-Centric Privacy: Transactions and debts between other group members remain strictly confidential. If other members log an expense or payment that doesn't include you, it never clutters your feed.
• Co-Paid Expenses: Most bill splitting apps only allow one payer. WhatDoIO lets multiple people chip in upfront for a single bill (groceries, Airbnb, flights, group dinners) and seamlessly calculates the split—whether divided equally, by exact dollar amounts, or by custom percentages.
• Anti-Tamper Audit Trail: Say goodbye to silent balance changes. Only an expense's creator can edit or delete their entry, and every modification is logged in a transparent revision history.
• Verified Settle-Ups: When someone logs a repayment, it remains pending until the recipient confirms receipt—preventing "phantom payments" and keeping balances completely honest.
• Locked Exchange Rates: Daily currency exchange rates are permanently frozen the moment a bill is logged. Your group balances stay immune to market volatility and post-trip recalculations across 7 global currencies.
• Active Session Offline Queue: Traveling abroad or in areas with spotty cellular connection? While you are logged in, temporary signal drops won't interrupt you—queue expenses offline with zero signal, and they will automatically sync to the group ledger the moment your connection returns.
• Smart Settlement: Automatically calculates the fewest total transfers to clear group balances quickly, with the personal option to settle directly 1-on-1 whenever you prefer.
Plus private group invite codes and optional biometric Face ID/Fingerprint security—everything you need for effortless, drama-free bill splitting is already built in.
