About this app
What Kitty does
Kitty is the friendliest way to track shared expenses for a trip, holiday house, or any group of friends. Create a group, add members, and log each expense in seconds — who paid, how much, and who shares the cost. Kitty handles equal splits and custom share weights, then distils all those IOUs into the smallest possible set of transfers so nobody has to do mental arithmetic at checkout. Everything lives on-device in SwiftData. No account, no internet, no subscription gating your data. When the trip ends, share a screenshot and you're done. • Unlimited groups and expenses, 100% offline • Equal or weighted custom-share splitting per expense • Minimal-settlement algorithm — fewest transfers to zero every balance • Running per-member balance visible at a glance • Multi-currency display per group • Export expense list as a shareable image or text summary

Share & export
Render the settle-up summary or the full expense list as a clean image the organizer can share to any chat app — no account or email required.
Why it exists
The problem
Group travel and shared-living expenses routinely devolve into tangled IOUs tracked in a chat thread or a messy notes app. Existing apps like Splitwise require accounts and increasingly push subscribers to a paid tier, while spreadsheets are too slow to update on the road.
What's different
How Kitty stands out
Kitty is fully offline and account-free with a minimal-settlement engine that collapses a week of expenses into the fewest possible transfers — unlike Splitwise (cloud, freemium with aggressive upsells) or basic calculators (no persistent groups). Its lightweight SwiftData model means the organizer can manage everythi…
