Split Cost Online

There are excellent apps to split expenses, but yesterday, I was with some friends and found that creating a group and adding everyone was a burden for a simple calculation. I thought that a small website (100% free) to add people and expenses with no sign-ups/ads (or downloading another app) would be helpful. So I created and published it. It is very simple but I think it is nice-to-have for one-day trips or activities.
