Worth opening
Notion

Notion holds the caps and the bills when that page is already on both phones.
Who it’s for
A light page is already a habit.
Who should skip
Skip it if Notion would be a new app this week.

Price
A free plan exists. Paid plans are on Notion’s pricing page.
Works on iPhone, Android, and the web.
Last checked
Setup on both phones
- Share one page to both phones.
- Write the caps and the bills due.
- Keep the gate code out of it.
What to put in it
- Grocery cap and activity cap, in dollars, where both of you can see them.
- Bills due this week, on the same page.
- The one text rule: what is worth a text, and what belongs on the calendar or the list.
Checked against Apple Notes
Apple Notes is enough when both phones already share one.
The downside
A new workspace will not get opened on a Tuesday.
