Author: MaliciousFiles

Your CGM glucose on your wrist: the current value, trend arrow, change since the last reading, and a smooth 3-hour trend graph colored by range.

Works with Dexcom G6 and G7 through Dexcom Share (the same service Dexcom Follow uses). No extra app on your phone: sign in with your Dexcom account in the app settings.

FEATURES
- Large value with trend arrow (all 7 Dexcom directions) and the change since the previous reading
- Countdown to the next reading; turns red when a reading is overdue
- 3-hour graph with a smooth line that shifts color with your glucose, guide lines at your low and high thresholds, and labeled peaks and troughs
- Clear states for LOW, HIGH, signal loss, sensor errors and connection problems
- mg/dL or mmol/L, with your own low and high thresholds
- Glance on supported watches, refreshed in the background
- Smart refresh: checks for data right after each new reading should arrive and learns your typical upload delay, so it's fresh without wasting battery

SETUP
1. In the Dexcom app on your phone, turn on Share and invite at least one follower (Dexcom Share stays inactive until you do).
2. Install Trendline, then open its settings in the Connect IQ app.
3. Enter the username and password of the Dexcom app that is sharing (not a follower's), and choose your region ("Outside the US" for Europe, etc.).

LOGIN NOT WORKING?
Dexcom reports every login problem as a wrong password, so check:
- Share is on and at least one follower has been invited.
- Phone-number usernames include + and the country code, e.g. +491701234567.
- Region matches your account.
- Your login works at uam2.dexcom.com (outside the US) or uam1.dexcom.com (US).
- Still failing? Enter your account ID as the username: after signing in at that site, copy the long code (like 1a2b3c4d-...) from the page address.

Pair with the Trendline Face watch face to see your glucose on your watch face.

IMPORTANT: Trendline is for informational purposes only. It is not a medical device and is not intended for diagnosis, treatment or dosing decisions. Readings can be delayed or missing. Always confirm with your CGM receiver or phone app before acting.

PRIVACY: Your Dexcom login is stored in the app's settings on your watch and phone. Because Garmin watches cannot parse Dexcom's login response format directly, the app sends your login over HTTPS to a small proxy that forwards it to Dexcom and returns readings. The proxy does not store credentials or readings.

**Note for reviewers:** enter `demo` as the username (no password) to see synthetic data. In demo mode, tap the screen to cycle through LOW, HIGH, signal loss, sensor error and no-data states.
