Same sensor, different philosophy
Both Levels Health and Nutrisense ship FreeStyle Libre sensors. The hardware is essentially identical. What you're choosing between is what happens on top of that hardware.
Levels Health bets that the right software — sophisticated metabolic scoring, deep wearables integration, food logging — can help self-directed people optimize their metabolic health without expert guidance.
Nutrisense bets that most people can't fully interpret CGM data on their own, and that a registered dietitian reviewing your data and giving personalized guidance is worth more than any algorithm.
Both bets are reasonable. The right choice depends almost entirely on which type of user you are.
App experience — Levels wins
| Feature | Levels Health | Nutrisense |
|---|---|---|
| Metabolic scoring | Detailed, proprietary | Basic |
| Wearables integration | Oura, Whoop, Garmin, Apple | Apple Health only |
| Lab results integration | Yes | No |
| Food logging | Excellent | Good |
| Data visualization | Best in class | Good |
| Educational content | Strong | Via coaching |
If you want the best data tools, Levels wins clearly. Its metabolic scoring system is the most sophisticated available in an OTC CGM app, and the depth of wearables integration is unmatched.
Coaching — Nutrisense wins
Nutrisense includes registered dietitian coaching. A real credentialed professional reviews your glucose data and provides personalized nutrition and lifestyle guidance via in-app messaging.
Levels does not include coaching. The app provides algorithmic insights and educational content, but there is no human expert reviewing your data.
This difference matters most for people who are new to CGM, have specific health goals like prediabetes reversal or weight loss, or who find data interpretation overwhelming without expert context. For these users, Nutrisense's coaching is worth significantly more than Levels' app sophistication.
Cost comparison
| Plan | Levels Health | Nutrisense |
|---|---|---|
| Monthly price | $199/month | $299/month |
| Annual price | $166/month | $179–199/month |
| CGM sensors | FreeStyle Libre (14-day) | FreeStyle Libre (14-day) |
| Coaching included | No | Yes — RD sessions |
On monthly pricing, Levels is cheaper. On annual pricing, the gap narrows significantly — and when you factor in the coaching value, Nutrisense may be the better deal for users who would otherwise pay separately for a dietitian.
