What YouLMK is

An inbox you let things interrupt you through: anything with an HTTP client sends into it, and you decide per sender how far a message may reach, whether quiet hours hold it and how repeats group. It can also watch a page, an endpoint, a status page, a feed, a number or a time, and send when the answer changes. The trial is 10 notifications and 3 watches, no card; the plans are $4 and $12 a month.
