Store description excerpt
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.
