ElectroCalc is another very useful application developed by SolarElectroCalc from India. It mainly focuses on power electronic circuit calculations on Android devices. It can help any people who are interested in electronic circuits to calculate circuits with ease.

Electrodoc (formerly called ElectroDroid) is a simple yet powerful collection of electronics tools and references specially made for all kinds of electronics developers, developed by IODEMA from Italy. It is of great help for both electronics students and engineers, and considered to be one of the necessary tools for electricians and workers in the electrical industry.

gEDA is a free, open-source and cross-platform (but mainly designed for Linux) EDA project. It provides a mature electronic design solution, including schematic diagram capture, property management, BOM (Bill of Materials) generation, 20 grid tables, analog and digital simulation, and printed circuit board layout (PCB suite, free software application).

DipTrace is a fully-functional circuit design software. It employs an intuitive user interface, supports multiple languages, is simple and easy to use, and has the shortest learning curve on the market and stable performance; supports layered schematic diagram, high-speed and differential routing, in-depth design planning with real-time DRC check, strong compatibility, etc.; and can exchange all data with EAGLE, Altium Designer, PADS and Cadence (OrCAD).

ELECTRA is a new generation of shape-based and automated routing software for PC boards, developed by KONEKT from Belgium. It can provide high completion rates for automated routing on the most densely populated multi-layer PCB designs. Compared with traditional grid-maze autorouters, the shape-based approach makes more efficient use of routing areas, and is better suited to deal with the complex design rules and requirements of high density SMD or through hole boards, thus achieving the highest routing completion rate.
