It watches the world while you sleep.

Sparks is a full autonomous tracking engine. Tell it what to watch — a product price, an eBay listing, a competitor page, a local folder, a market ticker — and it wakes itself up, fetches live data, evaluates the condition with the local model, and fires a push notification only when something actually changes or your condition fires. It doesn’t summarize on a loop. It tells you when it matters.
