Due to a programming error in version 8.2.2, a continuous cycle on the iPad cannot be canceled with the on/off switch.
Despite multiple attempts, I cannot reproduce this error.
LoCAD Lite is a free application for designing and simulating digital circuits. It focuses on easy creation and graphical visualization of how circuits function, allowing users to see current flow and state changes.
In the lite version, the number of usable elements per circuit is restricted to 13. This version is designed for simpler designs or introductory learning.
The app enhances understanding of circuit functioning by allowing users to watch the current flow and state changes during simulation. This visual feedback also improves the perception of circuit faults.
Yes, you can build complex circuits by creating your own custom integrated circuits (ICs) with nested levels. This allows for a more organized approach to designing large and intricate circuits.
The application includes a detailed introduction to help users familiarize themselves with the software. Its simplified wiring and graphical visualization are designed to make circuit design accessible.
LoCAD Lite is available for Mac and iPad devices. It was last updated on July 7, 2025, with version 8.2.3.
LoCAD Lite has a high user rating of 4.5 stars based on 2 ratings. The app is rated for ages 4 and up.
