Getting Started

What is Watta?

Watta is a rowing training log app that lets you capture workout data by photographing your Concept2 erg screen. We analyse your workouts and give you an Effort Score so you can track your training load over time.

How do I log a workout?

Tap the + button
Take a photo of your erg screen (or choose from camera roll)
Review the extracted data
Tap Save Workout

The app reads the data from your photo automatically. You can edit any values before saving.

What is the Effort Score?

The Effort Score (0-100) measures how hard your workout was, personalised to you. It takes into account:

Cardiac Load – Heart rate intensity (if available)
Work Output – Power × duration, adjusted for your body size
Pacing – Consistency bonus for even or negative splits
Economy – Stroke efficiency (watts per stroke)

Score	Zone	Meaning
0-25	🟢 Recovery	Easy, active recovery
26-50	🔵 Building	Aerobic base, steady state
51-75	🟡 Training	Proper work, building fitness
76-100	🔴 Peak	Race pace, max effort
