Motily: Sperm & Male Fertility
Habit Tracker & Semen Analysis
Only for iPhone
Free
iPhone
Free during launch. A two-minute daily check-in for men's fertility, built around the 74 days it takes to make sperm. Semen analysis results explained against WHO 2021.
Sperm health, two minutes a day.
Motily is a daily check-in for men who want to look after their fertility, whether you're trying for a baby now or planning ahead. Log eight research-linked habits, get a score for today and for the long run, and follow a 74-day journey that mirrors how your body actually makes sperm.
EIGHT HABITS, ONE SCORE
Sleep, nutrition, substances, heat, exercise, mood and stress, hydration and intercourse timing. Each one is linked in the research to semen quality. Tick through them in under two minutes and Motily turns the answers into a Today score and an Overall score you can watch move week by week. Answers that never change, like "I don't drink", can be set once and fill themselves in.
THE 74-DAY JOURNEY
Sperm take around 74 days to develop. Motily maps your habits onto that cycle in four phases, with weekly challenges and a celebration at each milestone, so the changes you make today show up in the sperm you produce two and a half months from now. Remy, your swimmer, keeps you company along the way.
UNDERSTAND YOUR SEMEN ANALYSIS
Had a test? Enter the numbers from your lab report and see each one against the WHO reference limits in plain English: what's in range, what isn't, and what tends to move it. Add later reports and track the change between them.
BRING YOUR PARTNER IN
Give your partner a code. She sees your day in the 74-day cycle, what that stage means for the two of you, your streak and whether today is checked in, on a web page or in the app, with no account needed. She can send you a nudge, share her fertile window so the timing prompts land on the right days, and you choose whether she also sees what you're working on or your scores. Never your answers.
ON YOUR HOME SCREEN
Add the widget and today's score and what's still to log are one glance away, without opening the app.
STAY ON IT
Streaks, badges and Swim Points reward showing up every day. Join a crew, add friends by handle and climb the leagues, or keep it private. Motily works either way.
APPLE HEALTH
Connect Apple Health and your sleep, workouts and steps fill in automatically, so the check-in gets even shorter. Health data is used only to power your own check-ins and scores, never for advertising, and you can disconnect at any time.
A COMMUNITY THAT'S ANONYMOUS BY DEFAULT
Ask the question you wouldn't ask out loud. Posts are anonymous, moderated, and you can report or block anyone at any time.
WHAT MOTILY IS, AND ISN'T
Motily is a lifestyle and wellbeing tool, not a medical device. It supports and informs; it never diagnoses, treats or guarantees an outcome. The research it draws on shows associations between these habits and semen parameters, not guarantees, which is why the app says "may" and "is linked to" rather than "will". If you've been trying for 12 months (or 6 months if your partner is 35 or over), or you have any concerns about your fertility, see a doctor or a fertility specialist. Nothing in Motily replaces that conversation.
PRIVACY
Your health data is yours. It's stored securely in the UK and EU, never sold, never used for advertising, and you can export or delete your account and all its data from inside the app. Read the full policy at motily.app/privacy.

Thank you for the first week. This update is the things you told us about.
- Text sizes: every screen now works with larger iOS text, including the quiz and the report entry steps.
- Check-in: the daily flow and every "start today's check-in" button follow the same order as the Today grid, strongest evidence first.
- Reminders: finishing a check-in no longer cancels the following days' reminders.
- Your plan: each "Start with" step is one small change for this week, with the numbers for your height and weight where you gave them.
- Where the numbers come from: sourced figures on the Analysis and Journey screens, and a clearer set of "Did you know" cards in the quiz.
- A quick way to rate Motily on the App Store, from Profile > Help or after a check-in.
- Smaller fixes and copy improvements throughout.
