> mobile app to store and use all your spare change

How exactly? I don't carry around a lot of change, but I can see some people use the app in some ways.

Sidenote: Here's a crazy idea I had a while ago. Allow users to take a photo of the change they have, and the app automatically sums up the change. I haven't done any research on this idea, so don't know if there's someone doing it, or if it's even possible.

I'm still working on the how. Currently building out a solution I've come up with.

I actually just watched a concept video for that very thing. I'll try to find the link. It would seem like a much faster process to just count the change yourself though, a lot less steps.

Or you know, I could just snap a picture, and be done with it. Again, optional, but would complement your app! Good luck.
