Tranqui helps you understand what shifts your energy and what keeps you centered. Most wellness apps reward extremes. More steps, more hours, higher scores. Tranqui is different. The goal is balance, not optimization. The center of the scale (45-60) is the sweet spot, not the top. TRACK YOUR BALANCE A simple 0-100 gauge shows where your energy sits each day. Log positive and negative actions and watch it shift. Lower energy days are valid. Rest days count as practice. BREATHE Guided breathing exercises built in. Box breathing, 4-7-8, resonant breathing, body scan, and grounding. On tough days, Tranqui gently suggests an exercise after you log. Accessible anytime from the home screen. DAILY INTENTIONS Three gentle intentions each day. Two complete automatically when you meet them. One is honor-based. No pressure, no guilt. CALM MODE Hide all points, levels, and gamification with one tap. Pure mindfulness. No numbers. Just awareness. PRIVACY FIRST No account. No cloud. No tracking. Everything stays on your phone. We never see your data. BUILT FOR PEOPLE, NOT OPTIMIZATION Tranqui was built by someone with OCD who found that most wellness apps made anxiety worse, not better. Every design decision prioritizes self-compassion over self-improvement pressure. Free to use. Premium unlocks unlimited history and advanced insights.
