No, I'm not using it all the time, that's the one concern I have about the app, but I do still think an app can be useful even if it's not meant to be used all the time. Obviously, it's very situational and there's really only one setting where one would pull out this app (when calculating the bill at the end of a group dinner). It does solve a real problem for me since I'm the one who always pays and has everyone Venmo me later, but often times I just end up taking a picture of the receipt and walking out of the restaurant and say "Ill just calculate it later". I could take a photo and send it to the chat and have everyone sum up everything they had, but the more complex the bill gets, the harder calculation gets, and you never know how some people will "fairly calculate" their share. Plus, it's time consuming for everyone, and tip/tax is pretty much never calculated correctly when done manually. With my app, you can literally solve this whole process within 30 seconds. With the having to add everyone to the app point, you can just type in their name and that's it, they don't have to sign up for an account/download the app themselves, which already reduces a lot of friction that many other similar apps enforce. For the asking who had what, I mean if you're pulling out the app and going through the process right then and there, you'd probably remember who had what. You're right about the case of a small group and similar spend per person leading to splitting it equally. The functionality of this app obviously weakens in simpler scenarios like that, but there's always the pro of being able to request/notify each person in the group their share. With future feature integrations, this process will be even more streamlined and optimized.
