iOS & Android
I've taken both of these far enough to know roughly what they'd cost to build and where they'd probably fall over. Both would keep everything on the phone: no accounts, no ads, no analytics.

ConceptUnbuilt
An app about paying attention to the people already in your day: the barista, the neighbor, the colleague you only ever small talk with. A prompt in the morning, two lines at night, and after ninety days it stops and asks if you want to go again. The ninety-day limit is the bit I care about.
ConceptUnbuilt
A log rather than a journal. Thirty seconds to record a strong reaction: the word for it, what it threatened, how hard it hit, and what it needs from you. Then one notification a day later asking where it's at now. Any single entry is useless; it gets interesting around thirty.

If you think either of these is a bad idea, I'd like to hear why. [email protected].
