Welcome

Sigma F is the premier site to get tutorials for your hand held devices such as calculators. Scientific calcutors, remote controls and phones are just some of the many devices that come with user manuals. There are many features on these devices that are under-utilized because of the difficulty of interpreting user manuals. Our simulators first address the use of the device as described in these user manuals. We then further expand the use of these devices by developing tutorials that address the more difficult features.

Check out our product list for the currently supported devices. Contact us if you have a device for which you would like to have manuals and tutorials developed.
