Sift strips a recipe page down to ingredients and steps, finds the recipe on its own through a Safari extension, and keeps your screen awake while you cook. Timers are parsed out of the steps. Saved recipes work offline. Free, no account necessary.
I built this because I cook from my phone propped on the counter, and every recipe page is an essay with a video ad in the middle of it. Then the screen goes dark every 30 seconds and I go into Settings, set the display to never sleep, forget to put it back, and my battery is dead by dinner.
Two things I would point at.
There is no error state. Parsing runs four levels down and the last level is you pasting the text in yourself, so every page lands on the same editable card. Nobody ever sees "this site is not supported," which is the message that gets an app deleted. It reads durations out of the step text, so "slow cook for 10 hours" becomes a timer that fires with the app closed.
It is free with no account and no ads. I would genuinely like to know which sites it fails on, so if you throw one at it and the parse is bad, tell me and I will fix it.
