I built a stock watchlist with no sign-up: a code instead of an account

I wanted a simple way to track stocks I don't own yet without making yet another account, so I built one. Instead of a login you get a code. Keep it and that's your list, on any device. What it does \- Set a buy target per stock and see when the price reaches it \- Returns from 1 day to 10 years, P/E with a sector comparison, and health/valuation ratings \- Quick filters: gainers, losers, undervalued \- Flags stocks near their 52-week high/low or with financial red flags \- Tap any stock for a chart and today's news What it isn't: a screener, a broker, or a subscription. No ads, no email. There's a demo list on the first screen, so you can try everything without a code. Link in the comments. Feedback very welcome, especially on what's missing.
