"Did you take your pill today?" never ask or answer again. Birth control shouldn't be one person's burden. PairCare lets couples share the responsibility. Your partner can check pill status themselves, in real time. Took a pill late? You know when you took it late on the shared calendar, so you both know exactly how many days to be extra careful. NEW: NOT ON THE PILL? TRACK YOUR CYCLE INSTEAD. Came off the pill, or never started? Switch PairCare to cycle mode and it tracks your period instead — same shared calendar, same partner who stays in the loop. Know where you are today: your current phase, your cycle day, and how many days until your next period. Log your mood, energy, flow and symptoms, and the guidance adapts to what you actually logged. Get a heads-up before your period arrives, and know when your fertile window starts — so you can be careful on the days that matter. And your partner can see it too. No more explaining why you're exhausted this week. They just know. Features: - Real-time pill status your partner can check anytime - Late pill tracker (know exactly when to be careful) - Cycle tracking with phase, period predictions and fertile window - Daily log for mood, energy, flow and symptoms - Guidance that adapts to your own logs, informed by NHS & ACOG - Send custom push reminders in your own words (Show your love) - Shared calendar for couples — pill or cycle - One subscription covers both partners - Gentle, caring, and cute design (Yes, I drew the cat animation) PairCare is built for couples who want less worry and more trust "together". PairCare requires a subscription, and every plan starts with a 7-day free trial. One subscription covers both you and your partner. PairCare provides reminders and general information only. It is not medical advice and is not a substitute for contraception. Terms of Use: https://paircare.love/terms Privacy Policy: https://paircare.love/privacy
