Cue
Read full descriptionHide full description
Most cycle apps are made for her. Cue is made for you, her partner. Cue takes the science of the menstrual cycle and turns it into plain, practical guidance. See what phase she is in, why her mood and energy are shifting, when her period is due, and what will actually help this week. No guesswork and no medical jargon. WHAT YOU GET • The cycle ring. Her current phase, cycle day and what comes next, with the ovulation and PMS windows mapped out. • Daily playbook. Three practical, phase-specific suggestions each day: what helps, what to avoid, and when to simply listen. • PMS heads-up. A quiet warning before the hard days, so you can lower the noise and bring patience instead of surprise. • Connection insights. Learn how her mood, energy and openness shift across the cycle, so you can pick the right moments for date nights, big conversations and quality time. • Conception mode. If you are trying for a baby, Cue treats the fertile window as a conception window, with timing tips and a two week wait guide written for him. • Cycle health awareness. Cue points out patterns worth a closer look, like irregular cycles, long or skipped periods, and early perimenopause signs, then links you to plain language explainers. • Knowledge base. Honest, readable articles on cycles, mood, connection, conception and reproductive health. Written for partners, not patients. PRIVATE BY DESIGN Everything you log stays on your phone. We never upload cycle data, symptoms, personal logs or notes, and there is no account to create. Anonymous usage analytics are opt-in and never include the contents of your logs. FREE TO START The essentials are free forever: the cycle ring, phase basics, period predictions and reminders. Cue Pro adds the full daily playbooks, connection insights, conception mode, cycle health alerts and the complete knowledge base. Every plan starts with a 7-day free trial. PLEASE NOTE Cue is an educational tool. It is not a medical device or a contraceptive method. Cycle predictions are estimates and can be wrong. Use reliable contraception if you are not trying to conceive, and talk to a healthcare professional about any medical concern.

Verdict
