Most mood trackers tell you what you felt. Felt shows you why: it learns which triggers lift or drag your mood, warns you when a rough stretch is forming, and celebrates when your week starts lifting. All of it 100% private and offline โ no account, no cloud, your feelings never leave your phone. Felt is a daily mood and emotion tracker built around one idea: naming your feelings precisely is itself good for you. Research by Dr. Lisa Feldman Barrett shows that people who use a richer emotional vocabulary recover faster, stress less, and have better mental health outcomes โ not as a result of therapy, but simply because of the naming. So we built a space to do exactly that, every day. THE MOODPRINT After each check-in, your entries are transformed into a six-axis emotional radar โ Calm, Happy, Energy, Focus, Social, Sleep โ grounded in Russell's Circumplex Model, the gold standard in affect science. Watch your week take shape. See the patterns you live inside but rarely notice. WHAT MAKES FELT DIFFERENT โ 9 core moods, carefully chosen to cover your full emotional range โ MoodPrint radar chart updates in real time as you log โ Pattern detection that spots rumination, volatility, and recovery trends โ Emotional Granularity Score โ tracks how your self-awareness grows over time โ No streaks. No guilt. No "you haven't logged in 3 days" shame nudges โ Notifications that feel like a gift, not a chore PATTERN DETECTION Felt quietly watches for patterns across your entries: rumination, volatility, emotional flatness, social withdrawal, concerning persistence, and โ the one worth celebrating โ recovery. When your week is genuinely lifting, you'll know why. BUILT WITH YOUR SAFETY IN MIND Heavy feelings deserve more than an algorithm. When your notes suggest acute distress, Felt steps back โ suppressing notifications, never adding pressure, and gently pointing toward real support when it matters. YOUR DATA STAYS YOURS All analysis runs on-device. Your journal never leaves your phone. Felt is not therapy. It is not a diagnosis tool. It is a daily practice of noticing yourself โ and noticing is where change begins. SUBSCRIPTION Full access to Felt requires a subscription.

Verdict
