Complements and syncs with the app

Photograph a marked page and Cupla Assist turns your handwriting into lists, dates and reminders. The only couples app with a hardcover companion whose pages become plans in the app.

Built on research

Couples who plan and dream together feel better about their relationships.

That finding shapes every tool on this page. Developed alongside Dr. Jessica Maxwell and Dr. Emily Cross, and tested with the couples who use Cupla every day.

Read the 2025 Impact Report

Within that survey, a longitudinal subset of 95 users was tracked across 2023 and 2024. The report also cites published relationship research (Ruffieux et al., Finkel et al., Wilcox & Dew).

The 2027 Impact Report is being prepared by Dr. Emily Cross, surveying over 2,000 users, our most extensive yet. Results due January 2027.

  • 20–30 min

    a week is the sweet spot

    Couples who spent about that long together in Cupla saw the biggest gains. It’s why the Weekly Sync guide is fifteen minutes and not an evening.

  • 5+ times

    frequency beats intensity

    Couples opening Cupla five or more times a week saw greater improvements in stress, communication and closeness than those who used it in longer, rarer bursts. It’s why the rituals guide favours small and often over grand gestures.

  • 76.3%

    said Cupla improved their communication

    And 63.5% said it helped them spend more quality time together, from our annual relationship survey of more than 2,100 users.
