Built a tool to see real ROAS (after refunds and churn) instead of what Meta reports

Built something to solve my own headache, sharing in case it's useful to anyone else here.

Every month I'd look at Meta's reported ROAS and RevenueCat's actual revenue and they'd tell two different stories. Trial starts counted as wins, refunds never subtracted, and by the time I noticed a campaign was actually losing money I'd already spent another few weeks on it.

So I built Sourceline. Connects to your RevenueCat account (read only, 5 min setup) and shows real ROAS per channel and campaign, churn adjusted, after refunds, not the inflated platform number. Only supports Meta for ad spend right now. Not live yet, still collecting emails for early access, it will likely be free while it's in beta. If you're running paid UA off RevenueCat and want in once itopens up, link's in my profile, would genuinely love feedback either way.
