Built Around the Warrior,
Built for the Circle
Here's everything LinkLoop does right now — and what we're working toward.
Home Dashboard
The moment you open LinkLoop, your warrior''s current glucose reading is front and center. Trend arrow, time-in-range ring, and color-coded status all in under a second.
- Current reading, trend arrow, and delta since last reading
- Time-in-range ring for the last 24 hours
- Color-coded: teal (in-range), yellow (high), red (urgent)
- Last sync timestamp so you always know data freshness
CGM Data Chart
24-hour glucose history pulled directly from the Dexcom API — not estimated, not interpolated. Every data point is a real EGV reading with its real timestamp.
- Up to 24 hours of Dexcom EGV readings
- Target range bands clearly shown on the chart
- OAuth 2.0 token refresh keeps data flowing automatically
Your Circle, Your Rules
The warrior owns their data entirely. Share access via private invite code — no email required for Care Circle members. Revoke any member instantly.
- Private invite code — generate and revoke with one tap
- View every active Care Circle member at a glance
- Revoke any member''s access instantly
- Care Circle members get read-only access — no settings control
AI Insights
Groq reads the glucose history and surfaces plain-English patterns. When does the overnight dip happen? What time of day runs highest? The whole circle can see it.
- Overnight trends, post-meal spikes, time-of-day patterns
- Plain-language summaries — no medical jargon
- Visible to both Warrior and every Care Circle member
- Powered by Groq with low-latency inference
Loop Member View
This is what a parent, spouse, or friend sees. Same live glucose. Same trend. Same data — just no ability to change anything. The warrior stays in full control.
- Same live glucose data as the warrior''s dashboard
- Trend arrow, range status, and last sync time
- Read-only — no settings or configuration access
- No Dexcom account needed for Care Circle members
Live Status Roster
When multiple people watch over a warrior, the roster gives everyone a glanceable status view without opening each profile individually.
- Color-coded glucose status for each member instantly
- Current reading and time since last update for everyone
- Designed for quick checks from a pocket or lock screen
Smart Alerts
Set your high and low thresholds once. When glucose crosses them, every Care Circle member gets the push notification simultaneously — not just the warrior.
- Configurable high and low glucose thresholds
- Push notifications to every Care Circle member at once
- Urgent low alerts cut through Do Not Disturb
- Persistent until acknowledged — nothing gets missed

⌚ Apple Watch FAQ
Common questions about the LinkLoop Watch companion.
Install LinkLoop on your Apple Watch from the Watch app on your iPhone. Open LinkLoop on your Watch, and it will display a 6-digit pairing code. Enter that code in the LinkLoop iPhone app to link your Watch to your Care Circle.
Long-press your Watch face and tap Edit. Scroll to the complication slots and choose LinkLoop. Three styles are available — Circular (bold number + trend), Rectangular (number + trend + timestamp), and Inline (compact single-line). Pick the one that fits your Watch face layout.
The Watch displays "--" when it hasn't received a glucose reading yet. This usually means the Watch hasn't completed its first server fetch, or the CGM hasn't reported new data. Give it a few minutes — complications update automatically every five minutes.
Yes. The Watch app fetches glucose data directly from the LinkLoop server over Wi-Fi or cellular — it does not rely on Bluetooth relay from the iPhone. As long as your Watch has a network connection, it works independently.
