BillSplit 2.2
(Edit)BillSplit is yet another restaurant bill splitter. We intentionally made it simple and easy to use. You do not have to spend 10 minutes after lunch typing what each person ordered and how much it costs - just type total and tip percent and you are done. If, for example, it ends up being $12.97 per person you can try to adjust per-person value to round number, say $13, and see how this affects total and tip percentile.
It is quite intelligent: you can edit not only tip percentile, but also adjust total or per person value.
