We build tools for emotional clarity

Mudo blends neuroscience, design, and thoughtful engineering to help people observe their emotional rhythm without friction.

We believe emotional literacy is the new productivity. Mudo started as a personal tool to manage startup anxiety and quickly became a shared ritual among friends.

Our craft is guided by an advisory council of therapists and neuroscientists. We uphold three principles: design for calm, respect attention, and own our impact.

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 listen inward.

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.
