The instrument is real
The EMF meter reads the phone's actual magnetometer. The SLS camera runs a real human-pose detector. The workbench stretches real recorded audio. Nothing on screen is theatre driven by a random seed.

Instruments for paranormal investigation.
We build handheld instruments for people who go into dark rooms on purpose. They sweep, read, record and timestamp. They never tell you what it means.

01 The instruments
Four devices, each for a different way of listening. They do not overlap, and none of them is a skin on the others.
02 The rule
This corner of the app stores is full of random number generators wearing lab coats. We took the opposite bet. Three rules, and we hold every release to them.
We never say it's a ghost
You get the reading, the recording and the timestamp. We will tell you that the pose detector locked onto an empty hallway — and why that happens. We will not tell you what was standing there. That call is yours, and it was never ours to make.
Bought once, yours
One price, paid once. No ads in a dark room, no subscription, no account, no telemetry, and no signal required — because the places worth investigating rarely have any.
03 About
Mortivox is the instrument line for paranormal investigation built by Codama, an independent software studio. Every app is written in-house, shipped on both stores, and supported by the people who built it.
Sound banks, word banks and detectors are built from scratch rather than licensed, which is why no two instruments in the line behave alike.
