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/
AVR Projects

AVR Projects is an app for those who are learning AVR Microcontroller programming, and it contains demo projects for makers, electronic enthusiast and engineering students. It focuses on ATmega328p, which is a microcontroller IC on Arduino Uno, and Atmel (Microchip) Studio IDE. * Learn AVR Microcontroller Programming with example codes in Embedded written on Atmel Studio IDE, Proteus simulation files, circuit diagrams and descriptions. * Easy to access sensors and ICs’s datasheets. More projects will be added soon!

Verdict
The clearest difference is update cadence: AVR Projects at daily against Circuit Simulator's every 6 weeks. Circuit Simulator's advantage is iOS requirement (15.3 vs 17.0). On price, ads, in-app purchases and device support there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. Circuit Simulator sells 8 in-app purchases, starting at $0.99 per month and AVR Projects sells 10 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.
Circuit Simulator ships an update every 6 weeks, AVR Projects daily. The most recent releases landed on October 25, 2026 and October 12, 2026 respectively.
