Interface and Ease of Use

The first thing you notice when opening PROTO is its clean and intuitive interface. The canvas for building circuits occupies most of the screen. On the right side is a vertical toolbar housing all the circuit components, analysis tools, and settings.

To place a component on the canvas, you simply drag it from the toolbar and drop it into position. Wiring up components is equally simple – you drag your finger between the component pins to draw connections. PROTO uses recognizable gestures like tap, hold, pan, and pinch zoom to make the interface feel natural.

Overall, the app is very easy to use. Within minutes, you can start building and simulating basic circuits without going through any tutorials. The interface has been nicely optimized for touchscreens.

However, the app lacks a comprehensive help section or tutorials for beginners. The component library could use more detailed descriptions and examples when you tap on each component. This would help new users understand how to properly use each part in a circuit.

Component Library

PROTO comes equipped with a decent library of over 80 analog and digital components. On the analog side, it includes resistors, capacitors, inductors, transformers, diodes, transistors, opamps, regulators, pots, switches, batteries, voltage sources, current sources, and more. For digital logic, you get logic gates, flip flops, muxes, counters, shift registers, decoders, etc.

Advanced components like BJTs, JFETs, MOSFETs, vacuum tubes, motors, and 555 timers are also provided. The component library covers most common parts you would need to build basic to intermediate level circuits.

However, there are some gaps when it comes to more complex analog ICs. For opamps, you only get generic models – specialized ICs like instrumentation amps, filters, comparators are missing. There are also no DACs, ADCs, voltage references, or other analog building blocks.

The digital component library lacks decoders/encoders, multiplexers, registers, memories, and other complex ICs. Adding these would allow more advanced digital circuits to be simulated.

Overall, the component library is quite good for education and hobbyist use. But professional circuit designers may find it lacking in depth compared to dedicated SPICE simulators.

Analysis Tools

PROTO comes equipped with a set of useful tools for circuit simulation and analysis:

Oscilloscope – PROTO provides a 4-channel oscilloscope that lets you visualize voltages in your circuit. You can pan and zoom the waveform, measure frequency, period, Vpp, Vrms, and other parameters. Cursors allow you to take precise voltage measurements on the waveform.

Multimeter – The multimeter tool shows detailed voltage, current, and power readings across any component or wire in the circuit. This helps debug connections and measure circuit performance.

Bode Plotter – The Bode plot tool is used to visualize the frequency response of a circuit by generating a Bode plot. This is useful for analyzing filters and amplifier circuits.

Waveform Generator – A function generator is available to stimulate your circuit with different waveform types (sine, square, triangle, sawtooth) and frequencies.

DC Sweep – DC sweep lets you sweep a voltage source or other DC parameter across a range of values. The tool plots how a measured voltage or current varies against the swept parameter.

Transient Analysis – This performs a transient simulation of your circuit with time-varying voltages and currents. The waveforms are plotted on the oscilloscope.

AC Analysis – AC analysis is used to simulate the AC/frequency behavior of the circuit. The voltage gain and phase can be plotted as a Bode plot.

Overall, the analysis capabilities are quite robust for a mobile circuit simulator app. The tools provide detailed insights into the circuit operation and allow in-depth performance analysis.

Simulation Speed and Performance

In terms of simulation speed, PROTO performs quite well. Simple circuits with just a few components simulate instantly. Even larger circuits with 20+ components simulate smoothly in real-time. Complex filters and amplifier circuits take a bit longer but remain very usable on most modern devices.

For digital logic simulations with lots of gates, you may notice some slowdowns as the app tries to propagate logic states in real-time. Performance ultimately depends on the complexity of the circuit and the processing power of your device.

On high-end phones and tablets, PROTO is able to simulate most circuits very efficiently. There is also a simulation speed control that lets you slow down or speed up the analysis. This helps keep even complex simulations running smoothly.

The real-time simulation approach sets PROTO apart from traditional SPICE simulators that require running a full analysis before results can be observed. The real-time engine makes the app much more interactive and engaging.

Advanced Features

Here are some of the advanced features that make PROTO stand out:

  • Animated Components – Voltages, currents, logic states are visualized animately as the simulation runs. This brings the circuit to life.
  • Interactive Wiring – Wires “snap” to component pins for easy connections. Existing wires can be dragged to reroute or create branches.
  • Undo/Redo – Every action can be undone and redone at any stage of designing the circuit. Very useful for troubleshooting.
  • Copy/Paste – Circuit fragments can be copied and pasted to reuse parts of a design. Helps speed up prototyping.
  • Zoom/Pan – The canvas can be panned and zoomed to navigate large circuits easily.
  • Dark Mode – A system-wide dark theme is supported for comfortable use at night.
  • Cloud Sync – Your circuits are synced across devices via cloud storage. Enables seamless transition between smartphones and tablets.
  • Offline Access – Circuits remain fully functional without an internet connection for on-the-go use.

These features really improve the user experience and differentiate PROTO from simpler circuit simulator apps. The animated touchscreen interface makes circuit simulation on a phone or tablet very intuitive.

Ease of Sharing and Exporting

PROTO provides a couple options for sharing your circuits with others:

  • Image Export – Any circuit can be exported as a PNG image. This captures the complete schematic as seen on the canvas.
  • Shareable Links – Each circuit gets a unique link that can be shared via email or social media to view the live simulation.
  • PDF Export – A PDF report can be generated with the schematic and simulation results.

The ability to publish a live simulation via a shareable link is very useful for sharing your designs and collaborating with others. However, there is no native way to export the underlying circuit netlist from the app. This limits interoperability with other tools.

Pricing and Licensing

PROTO offers a very generous free tier that is fully functional with no limits. All features of the app are accessible without any subscription.

Paid subscriptions start at $4.99 per month and allow you to:

  • Sync more circuits across devices
  • Remove ads
  • Get themes and custom app icons

For the average user, the free version has everything needed to get started with circuit simulation. The paid tiers add convenience but are not essential. This makes the app easily accessible for students, hobbyists, and educators.

Overall, the licensing model is quite fair compared to other electronics apps which impose tight limits on free users. PROTO’s free offering is full-featured and enables advanced simulation without restrictions.

Verdict

Overall, PROTO offers an excellent circuit simulation experience on Android devices. The real-time animated simulations bring circuits to life and make prototyping very intuitive. For education and hobbyist use, the app provides ample capabilities for learning and experimenting with basic analog and digital circuits.

Some gaps in the advanced component library limit the app for professional engineering use. But the generous free tier makes it easy for students and hobbyists to get started with interactive circuit simulation on their mobile devices.

PROTO compares favorably to other mobile-first simulators like EveryCircuit. The animated touchscreen experience is more engaging than traditional SPICE simulators like LTSpice which may be powerful but lack PROTO’s interactivity.

For anyone interested in learning about or prototyping electronic circuits on the go, PROTO is definitely worth trying out. The app can bring the excitement of circuit simulation to your smartphone or tablet.
