Period Tracker and Calendar is a health app in the lifestyle category that focuses on helping women monitor their menstrual cycles and fertile windows. I downloaded it from Google Play about six months ago, and it has become one of those apps I check daily. The app is completely free to download, which is great, and you don't need to register or give personal info if you don't want to. It has over 10 million installs, so it's pretty popular. There are no ads cluttering the screen, but there is a premium version with some extra features if you choose to buy it. It works on both Google Play and the App Store, so it's available for everyone.

Using this period tracker app is really simple. When you first open it, you just log your period start date and how many days it lasts. The app then automatically predicts your next period and ovulation days. I like that I can add notes about my mood, symptoms, and flow level each day. It helps me see patterns over time. A tip I learned is to log everything daily, even small things like headaches or sleep changes, because the app uses that data to give better predictions. The calendar view is clean and easy to read. You can also set reminders for when your period is coming, which has saved me a few times from being unprepared.

I have tried other period tracker apps like Clue and Flo, but this one feels less overwhelming. Clue has too many scientific terms, and Flo wants you to pay for everything. With Period Tracker and Calendar, I get all the basics for free. It does not try to sell me vitamins or push a community forum. I prefer simple tools that do what they promise. The prediction accuracy here has been very good for me. It is not the fanciest app on Google Play, but it is reliable. The developer SimpleInnovation keeps updating it, which shows they care. If you just need a straightforward period tracker without the extra noise, this app is a solid choice.

• 😊 Log your period, symptoms, and mood all from one simple screen. The calendar fills up with colored dots, so you can quickly see your whole month. Clue also does this, but it buries the log button behind too many taps. Here, everything is on the main page.
• 📅 Get accurate predictions for your next period and fertile window. The app learns from your history and adjusts over time. Flo gives predictions too, but it often changes them and asks you to upgrade for better accuracy. This app never asks for money to improve its guesses.
• 📊 View detailed charts of your cycle history. You can see patterns for flow, pain, and mood across months. Clue has charts, but they are hidden in a separate section and are harder to understand. The charts here are simple line graphs that make sense.
• 🔔 Set custom reminders for period start, ovulation, or pill taking. You choose the time and message. Flo charges for reminder customization. This app gives you full control for free.

• 💯 Completely free core features. No paywalls for basic period logging. Clue and Flo both hide important tools behind subscriptions. This app respects the user's need for a free tool.
• 🕊️ Lightweight and fast. The app opens instantly and does not drain battery. Some period trackers like My Calendar are bloated with extra stuff. This one stays lean and focused.
• 🎨 Customizable cycle length. You can set any cycle range, not just the standard 28 days. Other apps lock you into preset options unless you pay. This one lets you adjust freely to match your real cycle.

• 🚫 The UI looks a bit outdated. The design is functional but not modern. Flo has prettier graphics and animations. A visual refresh would make it more pleasant to use.
• 📱 No Apple Watch support. Clue and Flo both have watch apps for quick logging. This app lacks that feature, which would be handy during workouts or busy days.
