Your Readiness Score is not a snapshot — it is built from up to 12 weeks of your personal biometric data and updated every day. Here is how AlterMe Intelligence produces the number you see each morning.
It also provides insights into your overall physiological recovery and helps guide your daily activity levels.
Three layers go into your score
1. Your personal baseline comparison While you will receive your first Readiness Score 3 days after wear, AlterMe uses up to 84 days of your data to define a personal baseline for each biometric input. Your most recent data is compared against this baseline to produce the core, personalized component of your score. The longer you wear your ring, the more accurate this baseline becomes. Specific biometric inputs used include Heart Rate Variability (HRV), resting heart rate, breathing rate, and sleep efficiency.
2. Acute trends AlterMe also looks at shorter-term shifts — specifically changes over the last 3 days and a direct comparison of last night against the night before. This catches meaningful changes that a longer average might smooth over, such as a sudden HRV drop after a challenging training block or several nights of disrupted sleep in a row.
3. Population context A small portion of your score reflects where your data sits relative to population norms. This component carries progressively less weight over time as your personal baseline matures.
Each biometric input is scored individually. Your final Readiness Score is a combined, weighted score that accounts for interactions and multi-variable trends across all inputs — not a simple average. Key metrics influencing individual scores include HRV, resting heart rate, breathing rate, and sleep efficiency.
How your score matures over time
Days 1–13: Your score draws on a mix of your personal data and population norms. It is directionally useful but not yet fully calibrated to your biology.
Day 14: A meaningful threshold. Your score has enough personal history to begin reflecting your individual patterns rather than general benchmarks.
Day 21: Full maturity. AlterMe Intelligence is working almost entirely from your own data. Population norms play a minimal role from this point forward.
After day 21, every additional night of wear continues to refine your baseline, making the score more accurate over time.
Tips for Improving Your Readiness Score
To improve your readiness score, focus on optimizing the underlying metrics:
Maintain a Consistent Bedtime Routine: Go to bed and wake up at the same time daily to support circadian rhythm.
Incorporate Recovery Activities: Engage in relaxation techniques, light stretching, or mindfulness before bed.
Improve Sleep Quality: Aim for better sleep duration and onset by creating a conducive sleep environment.
Boost HRV and Lower Resting Heart Rate: Adopt healthy habits such as regular exercise, hydration, and balanced nutrition.
You can view detailed metrics and their impact on your readiness score by tapping on the score in the AlterMe app and exploring each section for insights.
Missing data
If you miss a night of wear, AlterMe fills in the missing biometric values using local medians from your surrounding data. This keeps your baseline stable so a single missed night does not skew your personal norms. Once you miss more than a set number of consecutive days, interpolation stops and your score is calculated using only observed data.
