The 5-minute rule
- One question per night
- No more than three lines
- End on "one small thing to try tomorrow"
Ten questions
- If there was a fork today, what would the other way have changed?
- How did the me in another universe spend today?
- Is there something I didn’t say today that the other me did?
- One thing I envy about the other me today
- One thing the other me would envy about me
- Someone I met today: what were we to each other in another universe?
- How would I explain today in one line to myself ten years ago?
- One scene from today I wouldn’t change if I lived it again
- What would the other me do first tomorrow morning?
- One piece of that I can borrow tomorrow
After a wistful question like 3 or 4, mix in one that accepts the present, like 5 or 8, so the journal doesn’t become a confession.
A reply to the other you
Once a week, swap the question for a three-line reply to the other you: a greeting, news from this side, and encouragement. It is like writing to your future self, but pointed sideways, which feels less heavy.
Using the app alongside

Let today’s universe set the question
The first screen of Parallel Lives shows a "Today’s universe" that changes each day. Use that universe’s job or place as material for question 2 and every entry turns out different.
The sample name in the screenshots is a placeholder; you can enter any name or nickname.
Read a letter, write back
Tap Open the letter on a universe card, read what the other you wrote, then reply in your journal. Settings offers light and dark themes; dark is easier on the eyes at bedtime.
FAQ
Is it pointless if I can’t write every day?
Not at all. One question whenever you feel like it is fine; don’t try to fill missed days.
Only regrets come to mind.
On those nights write just question 8, the scene you wouldn’t change, and close the book. If the thoughts keep hurting, talking to someone close or a professional can help.
