CENTRO is an emotional wellness app that guides you through nervous system regulation protocols designed for moments of stress, anxiety, sleeplessness, or lack of focus. This is not meditation. Not generic mindfulness. These are short, precise, science-backed action protocols that work directly on your autonomic nervous system. What is a CENTRO protocol? Each protocol is a voice-guided sequence between 3 and 12 minutes combining breathwork, eye movement, body anchoring, and sensory activation to shift your nervous system from a reactive state to a regulated one. 13 protocols for every moment: Night Switch - to turn off alert mode before sleep Reset 333 - to break the thought loop in 3 minutes Center Under Pressure - to perform under stress Field of Presence - to return to the present moment Body Anchor - for when the body won't stop Return to Axis - to recover your center after emotional impact Triangular State Change - to transition between states with intention Neural Loop Cut - to interrupt automatic patterns Focus Tunnel - to activate deep concentration Morning Reactor - to start the day with energy Impact Cleanse - to process difficult emotions Reset 333 Calm - gentle version for high-tension moments Reset 333 Night - to release the day before sleep Start with a personalized assessment of your emotional state and receive the protocol you need in that moment.
