Viv Signal

Apps and platforms built for movement.

Viv Signal designs and engineers digital products that are meant to be used, not admired. Its first product is Viv.

First product

Viv reads your Apple Health data on-device and tells you what kind of movement makes sense today, based on your own patterns, never anyone else’s.

Six signals

Each score answers one question.

Recovery

Is your body ready to be pushed today?

Body Energy

How much energy have you got to work with today?

Training Load

How is this week pacing vs your usual?

Effort

How hard was that workout?

Fitness Trend

How has your cardio fitness moved over 90 days?

Fitness Age

How does your cardio fitness compare to typical ages?

Three ideas, in plain English

  • 01

    Knows your body’s rhythm

    Personal baselines, not population averages. Viv compares you with you, never anyone else.

  • 02

    Tells you what to do

    Activity Guidance turns the day’s signals into one clear recommendation: full effort, light movement, or rest.

  • 03

    Honest about scope

    Every metric is explicit about what wearables can, and cannot, see.

Privacy

Your data never leaves your phone.

No servers. No analytics. No third-party SDKs. Viv reads from Apple Health on your device, computes your scores on your device, and stops there.
