Reviews
Trusted by professionals & students
Real users, real results — from solar installers in Texas to engineering students in New York.
★★★★★
The battery sizing calculator saved me hours on a 48V off-grid system design. Accuracy is impressive for a free tool.
★★★★★
The 3-phase power calculator is spot-on. I use it to verify load calculations before specifying transformers. Bookmark-worthy.
★★★★★
Used the excavation calculator on a residential foundation project. Saved us from ordering 30% too much fill material.
★★★★★
The GPA calculator is clean, fast and handles weighted grades correctly. Way better than the tools my university provides.
