Read the time clearly and see your recent heart-rate trend in one uncluttered view. Signal combines large digital numbers, a coral heart icon and a 30-minute heart-rate chart with two useful fields of your choice. YOUR RECENT HEART-RATE TREND The chart uses available timestamped heart-rate samples from your watch. Its vertical scale expands when needed, and missing history stays visibly missing instead of becoming an invented line. TWO FIELDS, YOUR CHOICE Keep steps and weather temperature below the chart, or select from 18 options: steps, temperature, battery, distance, calories, floors climbed, heart rate, Body Battery, stress, VO2 max, altitude, UV index, wind speed, respiration, pressure, active minutes, sunrise and sunset. Matching icons identify your selected fields; VO2 uses a compact text identifier. CLEAR EVERY DAY Date and battery sit above the large clock. Follow your watch's time preference or choose 12-hour or 24-hour time. Temperature, distance, altitude and wind use your watch's unit preferences. Supported field taps open the corresponding Garmin detail view. A MATCHING ALWAYS-ON DISPLAY On compatible AMOLED watches, Signal retains the full layout with an outline clock, subdued icons and a fine heart-rate trace on black. While asleep, the cached chart is labelled AS OF with its last refresh time. Compatible MIP watches keep the normal face in low power. We welcome feedback, bug reports and ideas. Use Contact Developer or email [email protected]. Data, history and tap navigation depend on your watch, permissions and settings. Unavailable readings display --. Weather temperature uses Garmin's available current conditions; the cloud/sun illustration identifies that field and is not a changing forecast icon. The chart is an informational display, not a medical or diagnostic tool. Signal displays data locally and does not send your activity information to an external service.
