I built a behavioral analytics tool for app builders — here's why and how A developer built AppScope, a behavioral analytics platform with an AI insight layer that automatically detects user churn patterns and narrates them in plain English. The tool requires only a single script tag and no dashboard configuration, aiming to solve the problem of silent user churn for solo developers and founders. The beta is now live and free to use. Every solo developer hits the same wall eventually. You ship something. You get users. Then one by one, they quietly disappear. No error in your logs. No angry email. Just silence. That silence is the most expensive problem in SaaS and nobody talks about it enough. I'd build a feature, ship it, and have no idea if anyone actually used it. I'd watch my user count slowly decline and have zero visibility into why. Was it the onboarding? A confusing page? A feature nobody wanted? The tools that exist to solve this Mixpanel, Amplitude, FullStory are powerful but they require you to already know what questions to ask. You have to build funnels, define events, set up dashboards. That's a full-time job. I didn't want a tool that gives me more data to interpret. I wanted something that just tells me what's wrong. AppScope is a behavioral analytics platform with an AI insight layer on top. The idea is simple: drop in one script tag, and within 48 hours the platform tells you what's broken in plain English. No funnels to configure. No dashboards to build. It just watches and reports. Here's what it detects automatically: Then it passes those detected patterns to an AI layer that narrates them like a product analyst would: "Step 2 is your biggest drop-off point, losing 4 users — double the drop at any other step. Review what's being asked there and either simplify it or defer it until users experience core value first." I deliberately avoided heavy frameworks. The SDK needs to be something any developer can drop into any app without worrying about bundle size or conflicts.
