Why does the Progress tab use Exponentially Moving Average (EMA) for tracking?

What is EMA and why is it used? 

EMA (Exponentially Moving Average) is a statistical method used in the Progress tab charts to smooth out your weight and strength data. It gives more importance to recent entries and less to older ones, creating a clearer view of your progress.

How does EMA help with weight progress? 

Your daily weight can change due to water retention, sodium intake, or meal timing. These short-term fluctuations can make raw data misleading.

EMA smooths out those ups and downs in the Progress tab, so your weight trendline better reflects real changes such as fat loss without overreacting to daily spikes.

How does EMA help with strength progress? 

Strength performance can vary between workouts based on recovery, fatigue, or sleep.

EMA emphasizes your recent results in the Progress tab charts, showing whether you are gaining strength, plateauing, or need to adjust training.

Why not just show raw progress data? 

Raw data is helpful but can be noisy. One heavy meal or one off-day in the gym can distort the Progress tab charts.

EMA reduces this noise while still being sensitive enough to highlight meaningful progress or plateaus.

Why use EMA instead of a simple average? 

A simple average gives equal weight to all data points. EMA instead:

• Responds more quickly to changes

• Prioritizes the most recent inputs

• Maintains smoother, more accurate progress trends

This makes it more effective for tracking real shifts in performance or body composition.

What if I miss a few weigh-ins or workouts? 

That’s fine. EMA works well even with irregular or missing entries. The Progress tab also uses interpolation (estimating values between points) to keep your progress trend reliable.
