Description
PROTO Mod APK is a circuit simulator that lets you build electronic circuits and watch them run in real time. You can follow current movement, adjust parts while a circuit is active, and test ideas without handling physical components.
Real-time circuit simulation
Animated current flow shows the direction of electricity through a circuit. This gives you a visual way to work through concepts such as Ohm's law and Kirchhoff's laws, while LEDs can light up as the circuit operates.
The four-channel oscilloscope lets you monitor several signals at once. You can inspect waveforms ranging from sine waves to more complex sawtooth signals.
Component values can be changed while the circuit is running, so you can see the system's response immediately instead of stopping the simulation first.
Logic components and digital circuits
PROTO Mod APK includes parts for basic exercises as well as digital-circuit projects. You can work with NAND and NOR gates, Flip-flops, 7400 TTL chips, and 4000 CMOS chips.
These components support designs such as counters and seven-segment decoders. Version 1.52.0 adds the 4518 dual BCD counter and the 4520 dual 4-bit binary counter.
Phone sensors and custom ICs
Your phone's light sensor, accelerometer, and gyroscope can act as circuit inputs. This lets a circuit respond to readings from the device itself.
You can also write JavaScript to control custom ICs. The latest version adds a Script IC with 32 inputs and 32 outputs.
Language and stability updates
PROTO Mod APK is available in French. Version 1.52.0 also includes bug fixes and stability improvements.

Mod Review
This build suits learners who want to change component values while a circuit is running and see the response immediately. It also fits users who need to inspect several signals through the four-channel oscilloscope. Skip it if the collection of app interactions, crash logs, diagnostics, device or other IDs, and purchase history is a concern. Version 1.52.0 adds the 4518 and 4520 CMOS logic ICs.
The MOD in practice
The MOD label is Premium Unlocked. PROTO Mod APK still centers on real-time circuit simulation, including animated current flow and live parameter changes. Its stated tools also include phone sensor inputs, JavaScript-controlled custom ICs, and a four-channel oscilloscope. The modified build carries the same Premium Unlocked label throughout this page.
What works
- Animated current flow makes circuit direction visible, which can help when tracing how a design operates.
- The four-channel oscilloscope monitors multiple signals together, useful for comparing sine and sawtooth waveforms.
- Live parameter changes let you alter a component while the circuit runs and observe the immediate response.
- Logic gates, Flip-flops, TTL, and CMOS parts support counter and seven-segment decoder experiments.
What to watch
- Google Play lists app interactions, crash logs, diagnostics, device IDs, and purchase history among collected data.
- Android 7.0 or later is required to install this 16.8 MB build.
- The latest update adds logic ICs and stability fixes, so compare its release notes with this build.
Our take
Install it when you want a circuit simulator with live controls, waveform monitoring, and digital logic parts. Check the collected data first, especially if device identifiers and diagnostics affect your decision.
FAQ
What is PROTO used for?
PROTO is a circuit simulator for building and running electronic circuits in real time. It shows animated current flow, can light LEDs during a simulation, and lets you change component values while the circuit remains active.
What does the Premium Unlocked MOD change?
Premium Unlocked is the MOD label for this build. PROTO still includes its stated circuit simulation tools, such as the oscilloscope, sensor inputs, and JavaScript support for custom ICs.
What digital logic components can I use in PROTO?
PROTO includes NAND and NOR gates, Flip-flops, 7400 TTL chips, and 4000 CMOS chips. You can use them for projects such as counters and seven-segment decoders, while version 1.52.0 adds the 4518 and 4520 counters.
Can PROTO use my phone's sensors in a circuit?
Yes. The light sensor, accelerometer, and gyroscope can be used as circuit inputs. This allows a circuit to react to readings from the phone.
What Android version is required for PROTO?
PROTO requires Android 7.0 or later to install. Android may ask whether you want to allow installs from this source, and that choice remains yours.
