I run interstitial ads in both my Android and iOS apps through several ad networks, but the current build gives me no clear picture of which network or campaign is actually pulling its weight. I need a clean attribution layer that captures every impression, click and post-click action, tags the event with the right source, and funnels the data into a report I can read at a glance. You’ll be working inside the existing flutter to add whatever SDK hooks, callbacks or server-side endpoints are required so that I can open a dashboard and instantly see which runner is driving the highest engagement or revenue. Whether the final stack involves Firebase Analytics, AppsFlyer, Adjust, a custom back-end parser, or something else, I’m happy as long as: • Each interstitial impression and click is tied to its originating network. • Metrics such as CTR, conversions and revenue can be filtered by network and time range. • The solution works reliably on both live apps with minimal impact on load times. • A short hand-off document and code comments explain how to expand or tweak the setup later. You’ll have Git access to both projects and all current ad network keys the moment we start. Looking forward to finally seeing which ads deserve the spotlight.
