With the danger of being labeled as almost elderly (once again): I found an app that I am so thrilled about that I just have to share it. It's the Who Pays What app. It seems that student houses have been using this for years excited about., but I lived alone during my studies so forgive me. That's why it's 2019 and I just now have it on my phone. The situation was as follows. One friend did the shopping beforehand, the other bought sandwiches in between, I tried to settle everything in the name of ‘easy‘ and that friend ended up paying for dinner in the evening, but then we were with four instead of six. I got hyperventilation at the thought of having to calculate this at the end of the weekend, so I had already resigned myself to a hundred unnecessary payment requests back and forth. But that is not necessary at all. Who Pays What settles everything, even if one person didn't go out to dinner and the other did, because then you simply don't include the other two in your calculation round. I'll stop my jubilation, otherwise I'll keep rambling about dividing by two or four or six. But are you going on vacation together or a weekend away? This takes away all the financial hassle and nonsense.
