About the Stability Score


The Stability Score feature makes it easier for you to achieve stable glucose each day. The Stability Score shows your daily progress achieving stable glucose, with a score out of 100, and highlights the portions of your day that have the highest potential for improvement.

Why is this important?

Reducing the number and duration of spikes and keeping a more stable glucose line throughout your day are short-term daily targets that compound into meaningful progress toward long-term metabolic health goals, including increased energy, longevity, and weight management.

Where is the Stability Score and Spike Detection located?

The Stability Score and glucose state description are located on your My Data tab.

How does it work?

With the Stability Score, you can see at a glance how each day’s stability went and track how your stability is trending day over day, with a score out of 100, where more points means more stable glucose. Levels’ spike algorithm detects substantial glucose excursions in real time, which can encourage you to take action to blunt a spike and observe how you feel when your glucose crashes. 
  • What range should I shoot for? The average Levels member gets a Stability Score score between 70 to 80 which is a realistic range to shoot for, and and above average scores are higher than 90.
  • What increases my Stability Score? The longer your glucose remains stable (i.e. fewer spikes) the Stability Score will rise
  • What decreases my Stability Score? If you experience glucose spikes, the Stability Score score will drop. Not to worry, though! If you regain glucose stability throughout the day, the Stability Score will recover. 
  • What's Std. Deviation (Variability)? Experiencing fewer glucose spikes and crashes in a day indicates more stable, controlled metabolism. We recommend trying to avoid meal related glucose spikes of more than 30 mg/dL. This will ensure that glycemic variability, which measures how "spikey" your glucose is throughout the day, remains fairly low. High glycemic variability (lots of spikes) can be associated with metabolic dysfunction, but keep in mind that some spikes from meals and exercise is expected,
  • How's Std. Deviation (Variability) measured? It is measured by how many mg/dL your glucose varies throughout the day from your average. The more stable your day, the lower your variability. Conversely, the more your glucose varies throughout the day, the higher your variability.
  • What is the optimal amount of Variability? A normal average for the magnitude of glucose excursions (difference between high and low) for someone who’s not obese and doesn’t have diabetes is between 26-28 mg/dL. We recommend trying not to exceed 110 mg/dL after a meal with no more than a 30 mg/dL rise from your pre-meal levels. For more info on variability, click here.
  • Will glucose spikes from exercise affect my Stability Score? No, they will not affect your score.

What is my baseline glucose?

Your baseline glucose is personalized to your data and is calculated based on the previous four hours of glucose readings. Levels will detect periods of stability, as well as glucose spikes that exceed +30 mg/dL from your baseline, and share whether your current glucose is  stable, spiking, crashing, or recovering

What does each glucose state mean?

  • Spiking: Spikes that exceed +30 mg/dL from your baseline glucose.
  • Recovering: Crossing and staying below the spike threshold in the 1-hour window after crossing.
  • Crashing: When you're 10 points below start of spike baseline, within 30-minutes of crossing below spike threshold.
  • Stable: There's no spike end time in the last 1 hour and you are not currently spiking.
  • Missing Data: No data if there are three consecutive 15-minute intervals with no data.

How can I view my trends over time?

Within the My Data tab, you’ll see trends of your stable hours and spike counts in My Data, and earn streaks for days without glucose spikes exceeding +30 mg/dL

By tracking these key data points separately, you can gain more insight into the ways that food, exercise, sleep, and other behaviors impact your glucose.
