How it works

Jevie checks prices every minute while the market is open, and coins around the clock, and a notice with its own sound opens that symbol's day. A condition you describe is turned into a small check once, tried on today's prices and shown to you, then runs each minute on its own.

When a watch finds out why, what it learned is kept as a market note with its sources, which memory can recall later.

Limits

• Prices can trail by about a minute.
• A level watch needs a symbol in the sentence: a price on a page is an automation.
• A condition is only as good as its check; read it on the card before relying on it.
• Prices come from Yahoo (stocks) and Coinbase (coins); watches and notes stay on your Mac.
