I made an iPhone app to turn messy “what if” loops into timelines and replay branches as short stories
I shipped an iPhone app called Decision Multiverse for people who already journal or want to start. You record a decision, the options, what you picked, and notes. Later you open a replay, choose a path you did not take, and read three compact branches that stay tied to what you wrote.
Branch AI can add richer branches when you turn it on and your setup supports it. If AI is off or the network fails, you still get deterministic on device templates so replay is not blocked.
No login in the default setup I describe here. Data stays on your phone in that model. Credits cover hosted generations where applicable. Purchases run through Apple In App Purchase.
This is for reflection and journaling prompts only. Not medical, legal, or financial advice. Not predictions about real outcomes.

I am genuinely curious what would make this more useful for weekly journaling habits, what feels missing, and what would annoy you fast. If you try it, tell me the first thing you would change.
