Your body is constantly spending and replenishing energy. ROVA's Body Battery distills recovery, sleep quality, and daily stress into a single 0–100 score so you always know how much you have in the tank.

How it works

Throughout the day we read your heart rate variability, activity, and rest. Deep sleep and calm periods recharge the battery, while intense training and prolonged stress drain it. The result updates in real time.

Training with it

A high score in the morning is a green light for hard intervals. A low score after a poor night is your cue to keep it easy or take a rest day. Over time, the trend matters more than any single reading.
