Ever wondered how your feelings change over time? That little moment when your crush looked at you, replied a little faster, or just walked past you… It might not seem like much, but when you're into someone, every second matters. This isn't just a journal. It's a space to track your emotions, analyze your love frequency, and see where your heart is headed. - Love Frequency & Attraction Signals What's your love frequency today? Are you stuck in an unrequited love zone, or is your energy pulling them closer? Find out if you're broadcasting the right signals for love, attraction, or even a text back. - Special Moments Calendar Love has its own milestones, even if it's one-sided. Save the first time they noticed you, the day you had the longest conversation, or when they liked your post. Every small detail makes up your love story. - Emotion Chart & Crush Trends Your emotions aren't random—track them like a pro. See how your feelings rise and fall over time, and spot patterns in your love life. Are you moving on, or just going in circles? - Ranking & Past Crush History Who’s been your longest-lasting crush? Your past loves tell a story. Analyze your dating patterns and see how your feelings evolved over time. You might be surprised by what you discover. - Reconnection Frequency & Relationship Mode Is it really over, or could there still be a spark? Check your reconnection frequency and see if there’s a chance to rekindle something. Even if you’re already in a relationship, you can use this to track your emotions and strengthen your bond. Love is unpredictable, but your feelings don’t have to be. Start tracking, reflecting, and maybe… tuning into the right frequency for love.
