Your health data should be more than scattered numbers. Lightive brings the Apple Health data you authorize, records you add, and health reports you upload into one timeline.

SLEEP AND TRENDS Review sleep stages, continuity and recent personal baselines to understand what changed overnight. Look back by date across activity, cardio and sleep so every signal keeps its original time context. AI HEALTH CONVERSATION Ask natural follow-up questions grounded in information you provide and health data you choose to authorize. Receive general wellness guidance that is easier to understand and act on. AI output can be inaccurate, so check important details against original data and professional advice.
