I've been wanting to build something like this for mobile advertising attribution. Mobile attribution is much worse since it by nature needs to on a device / fingerprinting level track across apps, and since there is not HTTP direct connection between the apps, the tracking is much more broad. Companies like AppsFlyer are in 20% of apps and track everything that happens in those apps.

I'd like to see AppsFlyer work on this as well. Moving mobile attribution to device based would be a huge privacy benefit. But it might be quite difficult for a company like AppsFlyer to do this, so it might need to end up being pushed by Apple and Google, but as both advertising companies, they might be even less incentivized for this kind of local tracking.
