My partner and I aren't married, but we live together and share a lot of expenses. Sometimes I'll pay for a bunch of cabs, and he'll pay for a couple dinners. Every few weeks, we get together and go through our credit cards to make sure no-one has overpaid their fair share.
Long story short, this was extremely manual, and everything in the App Store was way too complicated (Splitwise) for what we needed, or was way too manual. So I built the product that I needed, it connects to your financial institutions and allows you to select the expenses that you want to split, and how to split them. It just hit the App Store a week or so ago and I'm working on the distribution of that now to see if it has any legs.
Looking back, I should have validated the idea more widely, but I skipped over that part because it was fun to build, helped me learn a new programming language, and it was something I needed.
If you're willing to spare a few minutes to try it out, I'd love to hear your feedback.
Do you have this problem with your partner? Would our App solve that for you?
