⚡ PROTOSchem is a professional Android tool for creating wiring diagrams, electrical plans, and circuit diagrams directly on your mobile device.

📐 Designed for engineers 👷, technicians 🔧, students 🎓, and contractors working on real-world electrical projects, PROTOSchem combines precision and flexibility to support both industrial and residential installation tasks. Draw electrical schematics and single-line diagrams used in power distribution, control panel design, and complex installation systems. Plan and document electrical wiring with clear structure and logical organization, making your work easy to read, present on-site, or include in technical submissions.

🧩 Build complete layouts using an extensive library of electrical symbols — including switches, relays, transformers, breakers, contactors, protection elements, and home appliances such as air conditioners, washing machines, and electric stoves. With many of standard symbols covering industrial, commercial, and residential components, every project has the building blocks it needs from the very first sketch to the final design.

✨ Smart editing tools let you align components, label connections, drag, drop, rotate, and duplicate elements with speed and accuracy. Zoom and pan smoothly across your workspace to manage both fine details and large-scale projects without losing clarity. Structured layouts and consistent symbol usage ensure your diagrams remain readable and professional at every stage of development.

🌙 The clean, user-friendly interface works efficiently even on smaller screens, making it practical for both office work and on-site fieldwork. Built-in day and night mode ensures comfortable work in any lighting conditions — indoors, outdoors, or in low-light environments.

📤 Export your finished diagrams as PDF, PNG, or JPG for documentation, project submissions, or on-site reference. Whether you are designing control panels, developing new systems, or preparing technical documentation, PROTOSchem helps you produce clear, accurate, and professional circuit layouts ready for presentation or print.

🚀 From first concept to final documentation, PROTOSchem supports structured project development and gives engineers, technicians, and contractors a reliable mobile solution for everyday fieldwork, planning, and technical design.
