Looking for an app that quietly monitors burnout - any recommendations?

I recently went on sick leave because of stress symptoms. Looking back, I see the signs had been there for weeks, but I just couldn't recognize them at the time. As part of my recovery, I'm considering ways to prevent this from happening again. I'm searching for useful apps that can assist with this.

I’m not interested in a meditation app or a 21-day program. I want something that takes 30 seconds a day to log energy, sleep quality, and stress, and then stays out of the way until the data indicates I'm heading in a bad direction. Then it should notify me.

I don’t want a streak counter or a coach. I need a simple monitor that gently reminds me when I genuinely need it, not every day.

I've checked out Bearable (too focused on symptoms), Daylio (mood journaling, no real alerts), and Headspace (meditation-first approach). None of these meet my specific needs.

Does anyone know of an app that fits? Many thanks in advance!
