If you are in UK and need a new laptop with good performance for Biofield Viewer, we can send you a laptop preinstalled with Biofield Viewer and all the web apps at no extra cost.

Biofield Viewer runs well on all full Windows 11 and 10 computers. Here are suggestions to get the best machine. So long as the correct operating system type it will run well.

Windows 11,10 standard or Pro edition (not: RT, S*, X, IoT editions, or old 32 bit editions)
Apple Mac: The web edition of Biofield Viewer runs on all Apple devices directly.
The Windows edition running on Apple Mac isn't recommended due to DirectX 12 used by a future update may not be compatible with Parallels.

*Windows 10 S can be switched out of S mode to allow downloads such as Biofield Viewer, see

Display Full HD external monitors, IPS for wider viewing angle, are a more immersive and intuitive experience, also to extend a notebook.
If a notebook then Full HD 1920x1080 for high detail, ideally 17". A touchscreen is useful for pinch zoom of saved images.

SSD drive 1T ideally, or 500G is likely to be ok for the base system. Initially Windows uses only tens of gigabytes but likely to use far more over time. See USB ports below for how to expand drive space with fast access for large archives. 100G is likely to be used up in a few months to a year with videos. Older videos can be archived to external backup drives, providing more storage capacity later on. Remember to backup all files to independent storage.

System memory 8-16G ideal, 4G is fine for our software, but memory is fairly cheap so it could help to maximise memory at time of purchase. Memory can fill up and slow down a computer running many tabs in a web browser, so we recommend 8-16G.

CPU 64 bit, standard now. 8G+ of system memory is always 64 bit. Our software version 4 onwards requires 64 bit, while 3 will also run on 32 bit. Retailers don't quote speed test results for CPUs and GPUs, so we recommend checking CPU performance on 'Search for your CPU model' for example i3-7130U and you can compare with your previous computer.
Our test machine has CPU Mark 3928, and it's easy to find 10,000+ at a reasonable price. 4000 is fine for full maximum camera speed and resolution for the Logitech c922 camera below.
CPU speed will affect Chakra Mode, but it may help other features in future too, such as saved video quality.

GPU NVidia and AMD tend to be faster, but performance varies greatly so compare actual speed tests on
DirectX shader model 5 may be needed by a future update if we change to DirectX 12. Most recent cards support this.

USB ports vary greatly in their speed. You may need ports for external devices: camera, keyboard, mouse, display, file storage. USB hubs are available to add ports. USB2 0.5 Gbps is ok for keyboard, mouse and the Logitech c920 camera. USB3 5-40 Gbps is needed for efficient external file storage, and if fast enough an external display. For an external display and fastest access to file storage Thunderbolt4 copmpatible USB is 40 Gbps. The medium to faster USB ports may use the new USB-C physical connector, but that connector doesn't imply the full speed is available. New laptops may only have USB-C, so ensure the webcam is compatible or get an adaptor for USB-C to USB-A.


We use the Logitech c920 webcam for accurate real time video.
There is a wide range of webcams but we find the quality of subtle details which are important for our software varies considerably.
Any standard USB interface camera will work including non visual frequency IR and UV cameras.
Since new notebooks may come only with USB-C ports ensure the webcam is compatible with that or use an adapter.
For camcorder prerecorded video from its SD card use a yellow/red cable to USB video digitiser converter.

The c920 is usually available on Amazon for reasonable prices.
Download Logitech c920 G HUB  In G HUB 'Add new filter' to control the camera settings.

Ideally just a flat white wall will be fine.
