First time sharing an app here

My wife and I kept making small promises to each other (“I owe you a dinner”, “you pick the next movie”, “I’ll plan the weekend”) and then forgetting them

We tried notes and reminders, but they didn’t work well

So we built this small app as a game for us, where:

- One person creates a “check” (a promise/favor)

- The other redeems it when they want

- The partner marks it fulfilled

It allow you to keep track of dates, celebrations, ideas, memories; it's an space for you and your wife (or at least it's our space so far)

That’s the core

Everything else is optional

Over time we added:

- Shared calendar for dates and anniversaries

- Simple streaks and milestones (not social, not competitive)

- Shared wishlist and memories

- Time-delayed notes (“open in 6 months”) that your couple won't see

Design constraints:

- Private by default (just two users)

- No feeds, no public profiles

- No comparison between couples

It’s free with a paid tier of 1 USD for unlimited checks

This is mostly a lifestyle tool we wanted for ourselves, but we’re curious whether others have the same problem
