About Plask
GA4 analytics monitoring built by a developer who got tired of checking dashboards across 5 properties every morning.
Why Plask exists
If you run multiple websites or apps, you know the routine. Open GA4. Switch to Property A. Check active users, sessions, and engagement. Switch to Property B. Repeat. Do this every morning across 5 properties and it gets old fast.
The worst part isn't the time — it's the things you miss. A 40% traffic drop on a Friday evening goes unnoticed until Monday. A slow decline in engagement across your mobile app gets buried under noise. GA4 has powerful reporting, but it doesn't tap you on the shoulder when something goes wrong.
Plask was built to be that tap on the shoulder. It syncs your GA4 metrics daily, runs statistical anomaly detection using Modified Z-scores over a 28-day rolling window, and alerts you when something deviates significantly from its expected pattern. Every Monday, an AI-generated digest summarizes what happened across all your properties in plain English — written by Claude, not a template.
Built by Torstein Skulbru
Plask is built and maintained by Torstein Skulbru, a software engineer based in Norway with over 15 years of experience building production systems.
Currently at Ditio — a construction tech startup — and previously at TV 2 — Norway's largest commercial broadcaster — and Tietoevry, Torstein has spent his career working on systems where reliability and data accuracy matter. That experience is what drives Plask: the conviction that important metric changes should be caught automatically, not discovered three days later by accident.
Plask is an indie product, built with care and a focus on doing one thing well: keeping you informed about your analytics without the manual overhead.
What Plask does
Plask connects to your GA4 properties via read-only OAuth, syncs metrics daily, and gives you a unified dashboard with anomaly detection, AI-powered insights, and weekly digest reports. It monitors active users, sessions, new users, screen views, engagement rate, revenue, transactions, and event count across all your properties.
