Mortis is not a relaxation app. It is a precision nervous system training tool. Here's exactly what it does - and how it differs from everything else on the market.
Nine brainwave bands. 132 individual frequencies. Each with its own scientific overview, session duration recommendations, and use-case index. This is not a playlist. It is a reference library for your brain states.
OpenAI Whisper transcribes your voice. Claude analyzes your emotional and cognitive state. ElevenLabs generates a personalized guided session with a voice tuned to your exact words. No tapping through menus. Just speak.
Heart Rate Variability is the gold standard biometric for nervous system state. Mortis reads your HRV via Apple Watch HealthKit before every session and after. You see the delta. Every. Single. Time.
14 scientifically-validated breathing protocols with visual animation synchronized to your breath rate. HRV coherence tracking in real-time. Layer breathwork over any frequency session - or use standalone.
From the moment you start to the post-session HRV reading, every element is designed to maximize entrainment depth and physiological impact.
A training log, leaderboard, and accountability system built for people who treat their nervous system like athletes treat their body. Not a mindfulness forum. A training community.
The other apps are relaxation tools. This is a precision nervous system training tool. The difference matters.

Try the 40Hz gamma session. Check your HRV before and after. If it moves - you'll understand why this isn't like anything else.
