We build tools for anxiety clarity

Mudo blends neuroscience, design, and thoughtful engineering to help people track anxiety patterns without friction or AI.

We believe understanding anxiety patterns is the key to managing them. Mudo started as a personal tool to track startup anxiety and quickly became a shared resource among friends preparing for therapy sessions.

Our approach is guided by therapists and anxiety researchers. We uphold three principles: design for calm, respect privacy, and never use AI to analyze sensitive data.

The name Mudo nods to both the English word mood and the Portuguese word mudo, meaning mute. We create a quiet place in your day to track anxiety without judgment.

Our principles

  • Privacy-first — entries stay on device, always encrypted when synced.
  • Science-aligned — guided by CBT, ACT, and positive psychology research.
  • Design for calm — minimal screens, tactile feedback, gentle motion.
