Watches

When nothing can call you, YouLMK checks for you and tells you only when the answer changes.

Write it as a sentence

"Tell me when the MacBook Pro is back in stock on apple.com." YouLMK reads the target once, works out the type and condition, and shows you what it understood before anything runs. Every line is editable.

Intervals and fair use

1 min, 5 min, 15 min, 1 hour, once a day. Watch includes 100 watches and 100,000 checks a month; when the budget is used the fastest watches step down to hourly until the month resets. Pages that need JavaScript to render run every 15 minutes or slower.

When a watch cannot see

Three consecutive failures move it to Needs attention; a 403 or a bot challenge does so immediately. You get one Banner notification when that happens, then nothing more until you point it again.

Delivery

Each watch has its own Reach and its own destinations, set on the confirmation screen. A fired watch shows what it saw before and after, and how long the target had been unchanged.
