Frequently Asked Questions
How is WhisprJournal different from Calm, Headspace, and NEUROFIT?
WhisprJournal detects your nervous system state directly from your voice — pace, pauses, pitch, tension — and automatically matches you with a technique. Calm and Headspace are library-based meditation apps you browse yourself. NEUROFIT tracks heart rate variability through your phone's camera. WhisprJournal is also the only one built specifically on Polyvagal Theory, with an AI Coach grounded in your own pattern history.
Which of these apps is the cheapest?
WhisprJournal's core experience is free forever. Among paid tiers, WhisprJournal's annual plan ($69/year, about $5.75/month) is the least expensive compared to Calm ($79.99/year) and Headspace ($69.99/year). NEUROFIT doesn't publicly list an annual price; its quarterly billing works out to about $13.33/month.
Which app has AI coaching?
WhisprJournal, Headspace, and NEUROFIT all offer AI coaching. WhisprJournal's AI Coach is included with Pro and is grounded in your own Nervous System Profile — your actual voice-journal patterns over time. Headspace's AI companion, called Ebb, requires a separate $69.99/year add-on subscription on top of the base plan. NEUROFIT's coach, called CLEAR, is grounded in your HRV biometric data. Calm does not offer AI coaching.
