Murray Mood Sampler helps you capture how you feel in real time. Twice per day, you’ll receive a simple prompt: • How are you (0–10)? • What’s mostly on your mind? • What are you doing? That’s it. Over time, you’ll build a record of your emotional patterns — when your mood rises, when it dips, and what surrounds those moments. Why random prompts? Because memory is unreliable. Mood Sampler samples your experience as it actually unfolds.
