Common questions
What does the Biotracker measure that others do not?
It records resting heart rate and breathing rate continuously, alongside activity, using onboard AI validated by veterinarians. That cardiorespiratory monitoring is unique here and genuinely clinical in ambition.
Is it worth the price?
Only if you specifically want vital-sign data. For step and behaviour tracking, cheaper subscription-free monitors do the job. The Biotracker is for owners who want heart and breathing insights, often for pets with health concerns.
Does it need a subscription?
Yes, the full health and location features need a subscription, on top of a premium hardware price.
