Duet: Fertility for Couples

Trying to conceive shouldn't feel like guesswork. Duet gives you and your partner one shared plan: cycle tracking, timing, and daily habits, together.

Duet is the fertility app built for both of you. Most apps put the whole mental load on one partner. Duet turns trying to conceive into a shared plan, with a tailored experience for each of you on your own phone (or together on one).

Duet requires a subscription. One subscription unlocks all features for both partners:

TRACK YOUR CYCLE, TOGETHER • Cycle calendar with predicted fertile window and ovulation • Log periods, intercourse, ovulation and pregnancy tests in seconds • Your partner sees the fertile window too. No more "when was it again?"

FOR BOTH SIDES OF FERTILITY • A cycle-tracking view for one partner, a sperm-health focus for the other • Daily supplement tracking with streaks for both of you • Weekly check-ins on sleep, stress, energy, and intimacy. See how you're doing as a couple

LEARN AS YOU GO • Short, practical articles on timing, ovulation tests, sperm health, and the myths that waste your time • A weekly learning plan so you both stay on the same page

BUILT FOR COUPLES • Link accounts with a simple invite code, and each partner gets their own view • One phone between you? Single-device mode tracks both partners on one account • One subscription covers both partners

YOUR DATA STAYS YOURS • No ads. No analytics trackers. We never sell your data. • Your fertility data is shared with exactly one person: the partner you choose. • Delete your account and data anytime, right in the app.

SUBSCRIPTION DETAILS Duet requires an auto-renewable subscription: Quarterly at USD 20.99 per 3 months, or Monthly at USD 12.99 per month. One subscription unlocks Duet for both linked partners.
