This is going to sound strange, but the only thing that has ever worked for me was HQ, the live trivia game app. It was nightly at 9PM, so I'd my various daily tasks done and then I'd have to go to my bed to plug my phone in to play because it killed the battery. When it was over around 9:15 I was kind of settled in and would usually be able to fall asleep by 10 which is ideal for me.

So I guess if you can build in some sort of "hard stop" a little before you want to fall asleep that might work, but I haven't really found anything since.
