Trace lines up a patient's fitness activity data — from Strava, RideWithGPS, or an imported file — against their continuous glucose monitor readings from Nightscout, showing exactly what their glucose was doing before, during, and after exercise, minute by minute.
If you were sent a share block or a link by email or text, open the ☰ menu → Share access, and paste the block into "Import & connect." That's the only setup step — everything below covers viewing the data once connected.
The first thing you'll see is a summary of recent activities — hypo rate, average lowest reading, average heart rate, a quick trend chart, and a list to jump into any of them. Click the logo in the top-left at any time to come back to it. Change how many recent activities it covers using the buttons at its top right, use "Filter" there to narrow it down further, and use "Print / export as PDF" for a copy to bring to an appointment.
The sidebar on the left lists recorded activities by date — click one to load it, or click "▽ Filter" above the list to narrow it by type, heart rate, hypo status, or date first. The main chart plots time along the bottom, with heart rate and glucose shown by default. Hover anywhere on the chart to see exact values for that moment, in the "Point-in-time details" panel below it. The dashed band marks the activity itself; time before and after it is deliberately compressed so the workout stays readable regardless of how long the surrounding window is.
Click "Metrics shown" above the chart to toggle individual lines on or off — heart rate, speed, elevation, power, CGM, insulin on board (IOB), carbs on board (COB), basal rate, and more. Selections are remembered across activities and app restarts.
Glucose is shown in mmol/L by default. If mg/dL is more familiar, switch it in the ☰ menu → Nightscout connection — it updates the chart, tables, and comparisons everywhere at once.
Click "⤢ Full screen" to expand the chart to fill the whole display. Hovering there shows a compact, icon-labelled popup instead of the usual table — click "Icon key" next to the full screen button for what each icon means.
Select several activities from the sidebar (hold briefly on a phone, or use the checkboxes on desktop), then click "Compare." You'll get a summary table and a chart plotting effort against lowest glucose reached. "Find patterns" looks for a recurring threshold — duration, heart rate, effort — where glucose consistently starts dropping across the selected activities.
"View trends across activities" plots the lowest glucose reached in each activity over time, with a rolling average, so patterns across many sessions are visible rather than just one at a time.
If the patient's looping system logged a note alongside a bolus or carb entry, hovering near that point on the chart (within a few minutes) surfaces it — in full screen, it appears below the icon popup automatically.
This is a full copy of the same app the patient uses, not a separate restricted view — nothing you do here changes their underlying data, but the connections and settings are shared with whatever device this is running on, so it's best to avoid changing sources or credentials unless that's specifically what's intended.
