Put ad revenue and cloud bills on one chart so indie devs know if they are actually profitable

Problem: One developer shared their mini-program breakdown: only interstitial ads enabled because other ad ecpms are pitiful, a 3D model feature blew up CDN traffic costs, and the final tally was a 1659 yuan loss. Another posted revenue screenshots with ecpm peaking at 670. Their numbers differ by orders of magnitude, but neither had a tool to tell them which cost to cut.
Solution: Connect ad platforms and cloud billing to automatically aggregate revenue and costs, plot daily net margin curves, and flag cost ratios; alert when CDN, storage or ad revenue anomalies appear and simulate 'turn off this mode / switch to cheaper tier' scenarios.
Users: Indie developers shipping mini-programs and light apps, side-project PMs, and small teams monetizing through ads
MVP: Manual or CSV import of ad revenue and cloud bills; daily net margin curve; cost composition chart; anomaly alerts; one-click monthly review export
Revenue: Free for one product; subscription for multiple products and auto-synced cloud billing; discounted annual buyout
Why now: Mini-program creation is surging among Chinese indie devs and ad monetization barriers are dropping, but cost structures (CDN, storage, model calls) are getting complex enough that spreadsheets no longer keep up.
