That was where their process was breaking down - When did we buy this? How much was it? The sort of things that are semi-difficult to keep track of when you're going to A LOT of estate sales and then basically need to enter all the stuff into a spreadsheet when you get home.
So the concept was - take pics and enter simple data as you're out and about and then export the data when you get home.
I ended up going way down some deep rabbit holes because I didn't want to host any data (my goal was to actual release the app and hosting people's shopping trips wasn't something I wanted to take on).
So it's all local storage and for sharing between family members I ended up embedding the data in a pdf that you can send in a text and then import - so if x people are at the same sale they can all add to the same "trip" at the same time and then combine the trip when they're all finished shopping.
So image and data optimization were big concerns since it's all on your phone until you export it/delete the trip.
I was a fun process until it wasn't :P
I did end up getting to 1.0 and shipping to the app store, which was really my goal -> make an app and go all the way through the process. So in that way it was a success.
