Cronometer Integration: Connecting and Syncing Nutrition Data
CoachRx integrates with Cronometer through Terra so your client's calorie, macronutrient, and micronutrient data syncs into their lifestyle view. This article walks you and your client through connection, what data is pulled, the sync cadence, and how to fix common sync delays.
Who Sets It Up
Your client connects Cronometer from their CoachRx mobile app. You can't connect on their behalf - the connection is tied to their Cronometer account credentials. Once connected, the data flows automatically and is visible to both of you.
How Your Client Connects Cronometer
Open the CoachRx app on the client's phone.
Tap Profile > Settings > Integrations.
Tap Connect Cronometer.
The Terra connection screen opens. Sign in with their Cronometer credentials.
Authorize CoachRx to pull nutrition data.
Once the green confirmation appears, the integration is live.
What Data Syncs
Data | Synced |
Total daily calories | ✅ Yes |
Macronutrients (protein, carbs, fat) | ✅ Yes |
Fiber and sugar | ✅ Yes |
Micronutrients (vitamins, minerals) | ✅ Yes (where logged in Cronometer) |
Individual food entries | ❌ No (daily totals only) |
Photos of meals | ❌ No |
Sync Cadence
Initial sync: Up to 30 minutes after first connection to pull the last 14 days of history.
Daily sync: Automatic. New data flows in roughly every 4-6 hours during active days.
Edits in Cronometer: If your client edits a logged meal, the updated totals sync on the next cycle.
Manual refresh: Pull-to-refresh on the lifestyle view forces an immediate sync.
Where the Data Shows Up
In CoachRx:
Coach side: Open the client's profile > Lifestyle tab > Nutrition. Daily totals appear as a graph and a table.
Client side: Lifestyle > Nutrition shows the same data, plus their own personal target if you've set one.
Troubleshooting Sync Delays
Data isn't showing up after 30 minutes
Have your client open Cronometer and confirm at least one food entry exists for today.
Have them pull-to-refresh the Lifestyle screen in CoachRx.
If still nothing: disconnect and reconnect from Profile > Settings > Integrations.
Some days are missing
Cronometer only syncs days with at least one food entry. Days where your client didn't log anything will show as gaps - that's expected behavior, not a sync error.
Macros look wrong
Compare the day in Cronometer directly to CoachRx. If they match in Cronometer but differ in CoachRx, force a manual refresh. If they match in both but you expected different numbers, the issue is in Cronometer (food not logged, wrong serving size, etc.) - have your client review and re-log if needed.
"Authentication error" when reconnecting
This usually means your client changed their Cronometer password. Have them log out of Cronometer fully, log back in, then restart the CoachRx connection.
Other Nutrition Options
If Cronometer isn't the right fit, CoachRx also integrates with MyFitnessPal. See MyFitnessPal Integration for setup. Coaches can also log macro targets manually inside the lifestyle planner if their client doesn't use a tracking app.
