About PROTO
PROTO is an educational Android application released under the developer name PROTO. It is identified by the package com.proto.circuitsimulator and is delivered as a single standalone build that you install once and keep on your device.
Built as an Education Tool PROTO sits in the education category, which puts it alongside study aids and practice utilities rather than entertainment apps. The package name points to circuit simulation, so the app is positioned for learners, students, and hobbyists who want to work through electronic concepts in a guided, structured way on a phone or tablet.
Which Devices Can Run It The build requires Android 2026+ or newer. Devices running an older system than the listed minimum are not covered by this release, so anyone on legacy hardware should confirm their platform version first. Phones and tablets on the required platform or newer devices can install the package normally.
Storage Needed For Install The download is 23.5 MB, making it a lightweight entry that fits comfortably alongside your other applications. It will not demand a large amount of free space, and most devices with room for a typical education app will handle the install without needing to clear out media or archive files first.
Version and Listing Details The current release is version 1.51.0, published on 2026-09-14. The listing does not publish a content rating, so families reviewing the app for younger users should take that into account before handing over a device. Checking the version number confirms which build you have installed.
