Loggr

Loggr transforms your daily journal into a powerful health intelligence system by automatically extracting insights from your natural writing—all while keeping your data completely private and offline. Simply journal as you normally would, describing your meals, workouts, mood, sleep, or symptoms, and Loggr's NLP techniques analyze your entries locally on your device to track nutrition, activities, supplements, and well-being metrics without tedious manual logging or compromising your privacy.

You define what matters most by choosing and labeling your own goal variables—whether that's tracking migraines, back pain, anxiety levels, focus, energy, or any other aspect of your well-being—and Loggr automatically discovers what correlates with these outcomes. Unlike traditional health apps that force you into rigid data entry forms, Loggr believes tracking your health should feel as natural as having a conversation. It identifies patterns you might never notice on your own: discovering that your migraines correlate with certain foods, your back pain improves with specific stretches, or your anxiety decreases on days with morning walks.

Beyond correlation discovery, Loggr's A/B testing capabilities help you quantify the actual effects of lifestyle changes over time—scientifically measuring whether that new supplement really helps your focus or if cutting dairy truly reduces your inflammation. With beautiful visualizations, weekly insights, and an AI chat assistant to answer questions about your data, Loggr turns the simple act of journaling into a personalized health optimization tool—helping you understand not just what happened in your day, but what truly impacts the outcomes you care about most.
