Poker Ledger
Small enough that the only real design decision was the balance check.

The arithmetic is one division and one subtraction per player, so the tool is only worth anything because of the balance check. Doing the math by hand at the end of a night is where mistakes happen, and a total that does not come out to zero is a signal to recount before anyone hands over money.
What it computes
Two settings define the table: the dollar value of a buy-in and the number of chips a buy-in is worth. Dividing one by the other gives the value of a single chip. For each player you enter the total dollars they bought in for and the chips they finished with. The tool converts their dollars back into chips to get what they were owed at the start, subtracts that from their final stack to get net chips, and multiplies by the chip value to get net dollars. Players are entered as collapsible rows so a ten-person table stays readable on a phone.
Why the balance check matters
A home game is a closed system. Every dollar a winner takes came from a loser, so the net dollars across the whole table have to sum to zero. The tool adds up total bought in, total chips issued, total chips counted, and total net dollars, then flags the result as balanced or not. When it does not balance, the numbers are wrong and no payout should happen yet. Usually someone miscounted their stack or forgot a rebuy.
