Viv: Energy & Recovery APP

Viv answers one question every morning: what does my body have for me today, and what should I do about it?

Instead of drowning you in stats, Viv reads your overnight and activity signals from Health Connect and turns them into a single daily direction: push, hold steady, or recover. Every score is measured against your own baseline, not population norms. Your usual is the only reference that matters.

WHAT VIV GIVES YOU

Body Energy: a 0 to 100 read of what you have in the tank today, built from your sleep, heart signals and recent activity.

Recovery: how recovered you are from what you have done, from your nightly sleeping heart rate, sleep and training load.

Effort: how hard that workout really was, scored per session and across the whole day. Rate the sessions your heart rate cannot see, like strength work, with a quick 1 to 10 tap.

Training Load: Volts, an intensity-weighted load unit, with a weekly pacing read so you know if you are building or overreaching.

Movement: an adaptive daily step goal that flexes with your day. A hard session earns credit toward your movement target.

Fitness Trend: the long view of your VO2 max trajectory, so you know it is working.

WHY VIV IS DIFFERENT

Everything computes on your phone. No accounts, no cloud, no analytics. Viv reads your health data through Health Connect with your permission, computes your scores on the device, and nothing ever leaves it. On the Play Store data safety label, that shows up exactly as it should: no data collected, no data shared.

Personal baselines everywhere. Viv learns your usual over about four weeks and scores every day against it. A score of 50 means a normal day for you, not for some population average.

Honest degradation. Missing a signal lowers confidence; it never fakes a number. If Viv cannot score something, it says so.

WORKS WITH

Viv works best with a smartwatch that syncs sleep, heart rate and workouts into Health Connect, such as a Galaxy Watch paired with Samsung Health. Phone-only users get movement and activity reads, with sleep-based scores when a sleep source is available.

Viv is not a medical device and does not provide medical advice.
