Hydraulic Schemes is a free Android application that lets you create hydraulic diagrams for heat, cold, and air conditioning systems. Developed by Ángel Martínez, this app comes in handy for professionals and DIY enthusiasts who want to design their hydraulic diagrams quickly and easily.

The app offers a broad range of symbols such as valves, pumps, gauges, and many more. You can select the symbol you want to use, drag, and drop it to the desired position. The PRO version of the app allows you to open, edit, and save a scheme. You can also open several examples provided in the app, as well as share your work as an image, PDF, or file. However, the FREE version only allows you to create an outline and share it as an image, PDF, or file. Once a scheme is created, you won't be able to open another one. The FREE version also contains ads.

Hydraulic Schemes is compatible with Android 13.0 and requires no special permissions. The app is designed for Business & Productivity and is ideal for professionals and DIY enthusiasts who want to create hydraulic diagrams for their projects.
