@tykayn Agreed. The automatic donation part of this idea will be very, very hard indeed to implement. But it would be really cool if someone would make an app that just does the tracking part and gives you some nice looking statistics and tells you how much you should donate to each project according to how much you want to give each time period.
The stats part might even create some hype, just looks for example at how popular it is to share that Spotify Wrapped thing each year.
