iCircuit is the premier iPhone and iPad app for designing, simulating, and learning analog and digital electronics. Its advanced simulation engine provides real-time, always-on analysis so your circuits stay powered and live, just like working with real components. Use it like a CAD tool: add components, wire them up, and set their properties. But iCircuit is unlike typical CAD apps because it is always simulating. You do not stop to take a measurement or spend time configuring reports. Instead, you just play with the circuit as you normally would, with the power on. Build circuits with over 300 components, from simple resistors and LEDs to programmable Arduinos (Uno, Nano, Mega, ESP8266, ESP32), PIC microcontrollers, and 60 4000/7400-series digital ICs (more available with Pro). Connect elements, adjust values, and instantly see the results. BUILT-IN TEST EQUIPMENT • Multimeter: Probe any point to read voltage, current, and power • Oscilloscope: Track multiple signals with touch-controlled time scale, stacked/unstacked views, FFT analysis, and Bode plots • Gauges: Visualize voltages, currents, and frequencies directly in your circuit • Signal generators and configurable sources EXTENSIVE COMPONENT LIBRARY • Programmable Arduinos (Uno, Nano, Mega, ESP8266, ESP32) • Programmable PIC microcontrollers (assembly and HEX files, more available with Pro) • Power: Voltage regulators (78xx, LM317), sources, dependent sources, power jacks, and simulated antennas • Analog: Resistors, capacitors, inductors, diodes, BJTs, MOSFETs, thermistors, triodes, and tetrodes • Digital: Logic gates (AND, OR, NAND, NOR, XOR), JK and D flip-flops, and 60 4000/7400-series ICs (180+ available with Pro) • ADCs and DACs • Sensors and displays: LEDs, 7-segment, NeoPixels, matrix displays, thermistors • Electromechanical: Motors, servos, SPST/SPDT and DPST/DPDT switches, push buttons, relays, and speakers CREATE CUSTOM ELEMENTS Build sub-circuits and custom elements to componentize your designs and create reusable modules. Share your custom elements with others via the iCircuit Gallery. AUDIO SIMULATION Hear your circuits. Speakers, buzzers, and microphones produce real audio output. Perfect for students learning electronics, hobbyists prototyping projects, and engineers validating designs, all without burning out a single component. ABOUT ICIRCUIT PRO (OPTIONAL) iCircuit is a complete app with a one-time purchase. iCircuit Pro is optional and adds extra components (including more PICs and a larger 4000/7400 IC library) and helps fund ongoing development. Pro is not required for core simulation or everyday circuit design. Terms of Use: https://www.apple.com/legal/internet-services/itunes/dev/stdeula/

About

Evals Evolved

Features
Read full description

EvalsEvolved is a performance tracking and evaluation preparation tool designed to help service members document their work, accomplishments, and responsibilities throughout the year. Instead of trying to remember everything at evaluation time, users can quickly log daily tasks, ongoing duties, training, projects, and significant events in one place. The system helps organize entries into structured records that can be reviewed, summarized, and used to support performance evaluations. KEY FEATURES • Quick daily logging — Record work, duties, and accomplishments in minutes • Weekly and project tracking — Capture ongoing responsibilities and major events • Evaluation comment builder — Generate structured comments based only on user-entered data • Multiple entry styles — Log simple daily notes or detailed project summaries • Department and supervisor sharing — Users can choose to share records with supervisors or team members • Organized performance history — Maintain a continuous record of work completed over time • Secure user-controlled data — Users decide what information to record and share EvalsEvolved is built to support consistent documentation habits, reduce last-minute stress during evaluation periods, and help users maintain accurate records of their professional activities. The application supports multiple service branches, roles, and paygrades, allowing users to log responsibilities relevant to their specific duties. It is designed to be simple enough for quick daily use while still supporting detailed documentation when needed. DATA AND PRIVACY All entries are created and controlled by the user. The app does not generate or fabricate performance data. Information is stored securely and may be shared only when the user chooses to link with a supervisor or department. IMPORTANT NOTICE EvalsEvolved is an independent productivity and documentation tool. It is not affiliated with, endorsed by, or operated by the U.S. Department of Defense, Department of Homeland Security, or any government agency. SUPPORT For help, feedback, or feature requests, users can contact support through the official website listed in the Support URL section.

Verdict

The call

The clearest difference is price: Evals Evolved at Free against iCircuit's $12.99. Evals Evolved also leads on in-app purchases (none vs 2). iCircuit's advantage is update cadence (every 3 weeks vs every 3 months) and iOS requirement (12.2 vs 15.1). On ads and device support there is nothing between them.
