Add what everyone spent. Half Tab does the arithmetic and tells you the shortest way to square up — on your phone, with or without a signal.
A group lives on your phone from the moment you make it. Sharing is something you choose later, not a condition of starting.
Pick who is in it. Local by default — you can put it online later, or take it back off.
Equally, exact amounts, shares or percentages. Leave someone out of one line without removing them from the trip.
Send it in any chat, or let people scan the code. Nobody joins until you approve them.
Not everyone paying everyone. Check the summary, close the group, and send the whole thing as a PDF.
Every group is created and settled on your phone. No account needed, no signal needed. Nothing leaves the device until you decide to share a group.
Equally, by exact amounts, by shares or by percentage. Somebody skipped the paragliding? Leave them out of that one line, not the whole trip.
Whoever put the card down does not have to take a share. Record who fronted the money separately from who the cost belongs to.
One person covering a fixed part of a bill, a group kitty, or an office sponsoring the whole trip — all of it lands in the right place.
Put a group online and send a link, or let people scan its QR code. You approve who joins.
Before you close a group, check what each person ended up with — then send the whole thing as a PDF.
Half Tab is offline first, and that is a design decision rather than a feature. The database on your phone is the record — not a cache of something we hold.
Open it, add a bill, and it works. An account only exists so a group you share can follow you to another phone.
