Stress and Anxiety isn't a "journey." It's a physiological state that requires regulation. Most mental health apps treat you like a child. They offer cartoons, "streaks," and generic platitudes. Calibrate treats you like a complex biological system. We strip away the gamification and the over the top positivity to focus entirely on efficacy, speed, and data. Designed for skeptics and high-functioning professionals, Calibrate combines principles from CBT, ACT, and DBT with the hardware capabilities of your iPhone to provide a "panic button" for your nervous system. CORE FEATURES: Haptic-First Grounding When panic hits, cognitive function drops. Visuals aren't enough. Calibrate utilises the Taptic Engine to provide physical, rhythmic vibration patterns for breathing exercises. Engage your sense of touch to down-regulate your nervous system faster. Context-Aware AI Analyst Your stress has triggers. The Calibrate AI helps you find them. It doesn’t just offer generic advice; it acts as a clinical analyst, reviewing your habit logs and history to suggest precise interventions tailored to your current state. Correlative Habit Insights Stop guessing why you feel so stressed. Log your inputs (caffeine, sleep, work stress) and let Calibrate visualise the correlations. We turn your behavioural data into a clear roadmap for what helps—and hurts—your mental health. Live Efficacy Data Don't waste time on techniques that don't work. Access a live, data-backed view of which interventions are statistically reducing stress for the community right now. WHY CALIBRATE? No Fluff: No mascots, no guilt-tripping notifications, no spiritual woo-woo. Speed: The interface is designed for one-tap access to relief. Privacy First: Your mental health data is yours. Secure and private. You don't need another distraction. You need a tool. Download Calibrate.

Verdict
The clearest difference is ads: Re at none against ExTimer's shown. ExTimer's advantage is update cadence (every 11 days vs every 3 months) and device support (3 vs 1). On price, review sentiment, in-app purchases and monetization model there is nothing between them.
