The problem

Couples often drift apart not because of big issues, but because daily life gets in the way. Work, kids, stress: it’s easy to stop doing the small things that keep a relationship strong. And most habit trackers are built for one person, not two.

What we built

Duotone is a habit tracker made for couples. Create shared rituals, like morning coffee together, weekly date nights or daily check-ins, and keep them together. See each other’s progress, celebrate streaks, and build a stronger relationship one day at a time.
