Simplify's Take

What believers are saying

  • Google Play updated May 2026 and the app still ships active improvements.
  • App Store lists Zero Plus at $69.99, supporting premium monetization.
  • Zero's blog posted fresh 2026 health content, signaling ongoing engagement and acquisition funnels.

What critics are saying

  • Apple and Google can crush subscription economics if review quality slips in 2026.
  • Zero's Billings, Montana footprint and 2-10 headcount limit execution against larger wellness apps.
  • If fasting evidence weakens, Zero becomes a commodity app with weak defensibility.

What makes Zero Longevity Science unique

  • Zero rebranded from Zero Fasting in 2022, broadening beyond fasting into longevity.
  • Zero Plus launched in January 2026, showing product depth beyond a simple timer.
  • Zero spans iOS, Android, and web content, reinforcing cross-platform habit formation.
