Weekly Monitor is a research desk for running your own money: a 1,000-stock screener where every grade shows its formula, valuation models you can open and change, and a weekly review that keeps your decisions honest — written down, with reasons. Build it, know it, own it.
Free · runs in your browser · installs to your phone like an app · no account, no tracking
The app walks you through its own method — a checklist on the home screen tracks each step until the loop is a habit.
What every metric measures, the actual formulas, every symbol translated — in plain English, free to read here.
Ranked ideas where every grade shows its work. Tap “How this grade works” on any card and audit it.
Add your holdings — or load the sample book. Your data stays in your browser, full stop.
Flags become keep / trim / add decisions you write down with reasons — and review on a date you set.

ⓘ How this grade works — the five weighted components, the exact thresholds, and what data is missing. On every card.

Weekly Monitor is an educational research tool. It never tells you what to buy — it makes sure you understand exactly why a number moved before you decide.
Your portfolio, decisions, and theses live only in your browser’s local storage. No account. Nothing to breach, nothing to sell.
Quotes are ~15-minutes delayed and can be wrong or incomplete — the app says so on-screen, shows data freshness on every card, and degrades visibly instead of silently.
Works in any modern browser, on desktop and phone. On a phone, use “Add to Home Screen” and it installs like a native app — offline shell included.
