Intelligent Software with purpose.
We develop software that connects technology, research and human potential — from industrial automation to advanced biofeedback tools.
GDV Studio 
One brand. Multiple fields.
PICALLW combines decades of software development experience with new research directions.
Custom Software
Tailored business applications, system integrations, specialist desktop software and research-oriented solutions.
GDV Studio
Local GDV data analysis, visualisations, comparisons and professional reports.
NODVIA
Universal Automation Platform: NODVIA Field is the first practical step, NODVIA Studio designs and publishes HMI projects to Cloud, and NODVIA View runs them as a standalone Android runtime. Broader Connect, Core, Logic and Edge layers continue the platform.
Field + Studio + Cloud + View →Free IQ Test
A bilingual online test of logical, numerical and abstract reasoning with automatic scoring.
Digital Radionics
Experimental software for structured intention, symbolic protocols, sound and subjective biofeedback.
Technical knowledge, organised by domain.
Instead of an unstructured list of posts, the core content is connected into three paths — from fundamentals to deep field guides and research methods.

Research methods →World State Explorer — the world as a multidimensional time series.
A public PICALLW research environment for exploring repeatable relationships among financial, geomagnetic, weather, lunar, seismic and collective signals.
Discover → Validate → Replicate.
World State Explorer is designed to search for relationships that can be tested on unseen data rather than manufacture spectacular conclusions. It combines the World State Vector, lag analysis, Mutual Information, similar historical states and false-discovery control.
Software designed for your company—not the other way around.
We develop custom-made software in business informatics, industrial integration, data processing, reporting and specialised professional workflows.
GDV Studio
A desktop application for organised GDV data processing, clear result presentation and long-term measurement tracking.
