Pingle, the friend who knows your body's rhythm best

Pingle is more than just a simple period calendar. It records your daily changing condition, emotions, sleep, and symptoms, and analyzes your unique health patterns based on that data. Record your day comfortably, just like confiding in a close friend, without complex medical jargon. With Pingle, the signals your body sends will no longer feel unfamiliar.

Introduction to Key Features

📅 Smart Period Cycle Prediction Engine

Pingle's prediction engine doesn't simply repeat the average cycle. It categorizes the period start dates you record yourself and calculates your next period using a weighted average method that assigns higher weight to more recent cycles.

It's okay if your period is a little late. Pingle provides a 5-day delay allowance to notify you gently. It can track even irregular cycles with maximum accuracy.

If you are taking birth control pills, you can set the start date, dosage, and break/placebo method yourself. Based on the information you set, we automatically display on the calendar whether today is a dose day, a break, or a placebo period.

🗓️ Calendar Record Screen

You can check your daily records at a glance on the calendar.

Days when you are menstruating are filled in pink, and ovulation days in lilac, making it easy to visually track the flow of the month.

Tapping each date opens the detailed record screen for that day. You can intuitively input whether you are menstruating, the amount of menstrual flow, and the intensity of menstrual cramps using sliders. If you experienced irregular bleeding, you can also record the color of the bleeding and the time it was detected in detail.

You can select emotion stickers, physical symptoms, and even sleep status, and freely leave notes.

You can leave plans for upcoming dates. With a single tap, you can add preset items such as doctor's appointments, medication schedules, travel, or expected periods, or you can enter your own schedule.

🏠 Today Screen (Home)

This is the first screen you see when you open the app every day. Today's date and day of the week, a short quote from the mascot character Pingle, and your current cycle status are all displayed on a single screen.

The badge at the top indicates how many days into your period it is, how many days are left until your next period, and whether your period is delayed. It also sends practical notifications when your period is approaching.

If you haven't recorded your period yet, a check-in card appears; once you finish recording, the status changes to "completed." If it is your birth control pill day, you can check whether you have taken it with a single tap.

Your emotional records from the past 7 days are displayed as mini icons by day, allowing you to see your emotional flow this week at a glance.

📊 Rhythm Analysis Screen

Based on data from the past 30 days, it visualizes your emotions, symptoms, and sleep patterns using bar charts. You can grasp at a glance, "What emotions did I mainly feel this month?" and "What symptoms appeared most frequently?"

The cycle timeline immediately shows how many days into your current cycle you are within the overall average cycle. The duration of your period, the location of your ovulation, and the flow leading up to your next expected date are displayed on a single line.

The Prediction Accuracy section tells you how many days earlier or later your period was than expected, and how your recent cycles fall within a specific range.

You can also check daily changes in menstrual pain intensity during your period.

✨ Insight Engine

Pingle doesn't stop at simply displaying data. Various precise conditional rule engines analyze your records to automatically select and show you the insight cards you need most right now.

🤖 AI Analysis and AI Chat (Premium)

By synthesizing your menstrual records, pain intensity, emotions, symptoms, and sleep data from the past 14 days, the AI ​​analyzes your physical condition for this cycle in 3 to 5 sentences. It reads out your patterns in a warm and empathetic tone rather than a medical diagnosis, and concludes with a word of encouragement. The analysis results are saved in the daily cache, allowing you to check them quickly without needing to make repeated requests on the same day.

You can also use the AI ​​chat feature. Tapping the mascot button floating on the screen opens a chat modal, allowing you to converse with Pingle based on your health history data. Since it answers questions while remembering the context of previous conversations, you can receive advice perfectly tailored to your situation.

💑 Partner Linking (Couple Feature)

This is a special feature unique to Pingle. If you issue an invitation code and connect the app with your boyfriend, your cycle status and today's condition will be summarized and displayed on his screen.

It is enough for me to simply record my own history. Your boyfriend can see how many days into your period you are, what emotions you are feeling, and what symptoms you are experiencing. You can directly control which information to share—mood, symptoms, and notes—using switches, allowing you to select and share only what you want to show.

Your boyfriend can leave a short message of encouragement, which appears as a speech bubble at the top of Pingle's home screen. There is also a cycle care guide feature that provides personalized behavioral tips depending on whether you are currently on your period, in the luteal phase, or during ovulation.

Even if the couple connection is severed, data is frozen and stored for a 30-day grace period. Upon reconnecting with the same account, all existing records and assets will be restored.

🎮 Ping Pong (Couple Shared Space)

This is an exclusive space accessible only to connected couples. Your boyfriend can leave a "Message of the Day" every day.

You can leave a secret letter that opens on a specific future date using the Time Capsule feature. You can include not only text but also Polaroid photos and 30-second voice messages. Letters cannot be opened until the designated opening date.

You can share YouTube music you want to play for each other using the "Today's Playlist" feature. Purchasing the LP Player item changes the music playback screen to a rotating LP record design.

Purchasing the Snowball item creates a snowball containing a photo of the two of you. You can purchase items and decorate the space using Jelly (couple currency) at the Couple Store.

🛡️ Safe (Settings and Privacy)

You can set up biometric authentication (Fingerprint/Face ID) for the app lock feature. Even when turning on the lock, it is only activated after you have actually passed identity verification, ensuring strict security.
