Smartphone application for recording chastity progress and events (not limited to unlock methods)

I’m new to both this community and smartphones. I was curious if there’s a dedicated app for tracking progress while locked down? I did a search but didn’t spot any that specifically document things like when you had your last orgasm, or were milked, or released—sort of like a logbook. Of course, I suppose I could just jot notes in my phone’s calendar myself.. hmm, maybe I’ve answered my own question..

Anyway, does anyone know of an app suited for this? thanks ahead of time
