If you’ve ever lost track of when your period is coming, when you’re most fertile, or why your mood shifts week to week, you’re not alone. Most period trackers flood you with ads and features you’ll never use. I built Momo Calendar to solve the opposite problem: give you exactly what you need, nothing more.
I created this app because I wanted a period tracker that respected my privacy and didn’t waste my time. Too many apps in this category either require constant setup tweaks, bombard you with marketing, or make you second-guess whether your data is actually private. Momo Calendar does one thing well: you enter your period start date once, and it automatically predicts your next period, fertile window, and ovulation day. From there, you can log as much or as little as you want—flow, pain, symptoms, mood, contraception, or intimate moments. The app learns your personal cycle patterns and shows them back to you as clear statistics.
What It Does
- Smart prediction: Input your period start date and get automatic forecasts for your next cycle, fertile window, and ovulation day. Customize your average cycle length and period duration as your body’s patterns emerge.
- Daily logging: Track flow intensity, pain level (0–10 scale), symptoms (headaches, cramps, bloating, acne), mood, and free-form notes all in one place.
- Contraception and intimacy: Log oral contraceptive use, emergency contraception, and whether intimate moments were protected or unprotected—privately, without judgment.
- Calendar and insights: See your full month at a glance, then dive into charts that visualize your symptom, mood, and contraception patterns. Track your average cycle length and see how accurate the predictions have become.
- Security and reminders: Set reminders for your period, ovulation, or daily logging. Lock the app with a PIN so no one else can access your data if you lose your phone. Choose between light and dark themes, and pick your language (Korean or English).
Who This Is For
This app is for anyone whose cycle isn’t perfectly regular—which is most of us. It’s useful if you’re practicing natural cycle awareness or trying to conceive, if you forget to take your daily pill, or if you simply want to see data-driven patterns in how your body feels. It’s also built for people who’ve abandoned period trackers because they were too complicated or too ad-heavy. If you want a tool that stays out of your way and keeps your information truly private, Momo Calendar won’t let you down.
All your data is encrypted before it leaves your device, synced securely to your account, and completely deleted if you choose to leave. There’s no third-party tracking, no behavioral ads, no dark patterns. Just your calendar, your data, and your privacy.
Momo Calendar is available now on the App Store. Download it, enter your period start date, and let the app take care of the rest. If you have feedback or questions, I read every message at siwooeo@gmail.com.
