Actogram

The body runs on biological time. Actogram is built to measure it. We are a Barcelona-based startup developing ultra-low-power circadian rhythm analytics technology for wristwatches. We know how the timing and stability of rest-activity patterns connect to biological rhythms, longevity, and long-term health — and we translate that science into technology that works inside real devices. Our technology is patent-pending, validated on population-scale datasets. We are building a full circadian health stack: analytics, consumer products, and purpose-built hardware. For wearable manufacturers, watch brands, digital health platforms, and longevity researchers.
