Period Calendar Period Tracker is a health and fitness app designed to help you track your menstrual cycle and understand your body better. It's a straightforward tool I found on Google Play a while back. The app launched several years ago and has been downloaded millions of times, which shows how many people trust it. You can get it for free on both Google Play and the App Store. When you first download and install the app, you don't need to register right away, which is nice for privacy. You can start logging your period dates and symptoms immediately. There are no annoying ads popping up all the time, and while there are some in-app purchases for extra features, the free version has everything most users need for basic tracking. I've been using it for over a year now to keep an eye on my cycle length and predict my next period.

Using the app is really simple. After you install it, you just tap to mark the first day of your period. The app then shows a calendar view with color-coded days, so you can see your cycle at a glance. I also use it to log symptoms like cramps or mood swings, which helps me see patterns over time. A simple tip from a regular user: make sure to log your period start date as soon as it happens for the most accurate predictions. The app will send you a reminder notification if you want it to. You can also track things like flow, energy levels, and even intimate activity. It's become part of my daily routine to just open the app and quickly note how I'm feeling.

Compared to other period tracker apps out there, I chose Period Calendar Period Tracker because it feels less cluttered. Some apps have too many social features or complex charts that I don't need. This one keeps things clean and focused on the basics. While apps like Flo or Clue are also popular, I found this one to be more private and straightforward. It doesn't ask for a lot of personal details. For someone who just wants a reliable way to know when their next period is due, this app does the job well without any fuss. It's my go-to app for cycle tracking because it's simple and gets the predictions right most of the time.

• 📅 The main screen is a clear monthly calendar where you tap to log period days, ovulation, and symptoms. It's much simpler than Clue's interface, which can feel a bit scientific.
• 📊 It provides easy-to-read charts for cycle length and period history. This visual summary is more immediate than the data presentation in some other trackers.
• 🔔 You can set custom reminders for your predicted period start, ovulation, or to take pills. The notification system is more flexible than the basic ones in many free apps.
• 📝 The symptom and mood logging is very quick with tap-to-select options, making daily logging faster than typing notes in apps like Flo.

• 👍 Its prediction algorithm for period and fertile windows has been very accurate for me, often more reliable than other free trackers I've tried.
• 👍 The design is clean and unintimidating, which is great for new users compared to some apps that feel overwhelming with data.
• 👍 Strong focus on privacy with local data storage options, which feels safer than apps that require cloud sync by default.

• 👎 The free version has limited customization for cycle insights compared to premium features in apps like Flo.
• 👎 Occasional syncing delays if you use the backup feature, which isn't as smooth as in some competitors.
