Products like TempDrop and Ovusense, are they worth it?


Like most of you, I’m sure, I get targeted ads like crazy on Facebook, Insta, etc. Among them are these two products and they’re fairly prevalent. Of course, I have clicked on them in the past which is likely why they continue to cycle back in my feeds. Has anyone used these with success? Are they just a scam? Are there similar items I haven’t been exposed to that do work? I was mainly interested because I can forget to temp in the morning, or I’ll wake up briefly and go back to sleep for an hour or so and wonder if the temp would be invalid since I was already awake, but didn’t measure. Among other things I’m curious to get as much information about my cycle as I can from other sources beside temping, testing with OPKs, and self-exam.
