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.
