Circuit Simulator vs Benchbuilt

VoltSim is a realtime electronic circuit simulator like Multisim, SPICE, LTspice, Altium or Proto for circuit design with a better user experience. VoltSim is a complete circuit app in which you can design circuits with various components and simulate an electric or digital circuit. During simulation you can check voltage, current and many other variables. Check signals on multichannel oscilloscope or multimeter and tune your circuit in real time! You can also use VoltSim as logic circuit simulator and perform digital electronic analysis! This app will help you visualize how the voltage varies across the circuit and how current flows through it. T&C: https://www.apple.com/legal/internet-services/itunes/dev/stdeula/

Benchbuilt turns vehicle engineering into a hands-on learning lab. Start with a production-inspired body, choose an engine, configure the drivetrain and chassis, then shape the body and test the result. Every choice feeds a physics-based estimate using real units and understandable explanations. Compare power, mass, frontal area, drag coefficient, traction, gearing, braking, and engine packaging without needing an engineering degree. BUILD YOUR VEHICLE • Choose from compact, fastback, roadster, sports sedan, and open-engine hot rod body packages • Install engines ranging from an efficient four-cylinder to high-output V8 packages • See whether the engine fits beneath the body or protrudes into the airflow • Configure transmission, tires, brakes, suspension, chassis weight, and fuel • Shape independent body control points to explore smooth profiles, wedges, and experimental designs TEST AND LEARN • Estimate top speed and 0–60 mph acceleration • Measure quarter-mile time and trap speed • Compare standing-mile speed, lateral grip, braking distance, and cruise range • Run road and wind-tunnel tests • Understand why drag, weight, power, traction, and gearing changed each result • Save builds for side-by-side engineering comparisons Designed for curious builders, students, classrooms, and anyone who has wondered why one car shape performs better than another. Benchbuilt works on iPhone and includes a spacious iPad workbench for classroom use. Benchbuilt provides educational physics estimates and is not intended for real-world vehicle certification or safety decisions.
