Pydroid 3 is the most easy to use and powerful educational Python 3 IDE for Android.

Features:
- Offline Python 3.6 interpreter: no Internet is required to run Python programs.
- Pip package manager and a custom repository for prebuilt wheel packages for enhanced scientific libraries, such as numpy, scipy, matplotlib, scikit-learn and jupyter.
- Examples available out-of-the-box for quicker learning.
- Complete Tkinter support for GUI.
- Full-featured Terminal Emulator, with a readline support (available in pip).
- Built-in C, C++ and even Fortran compiler designed by n0n3m4, an author of C4droid, specially for Pydroid 3. It lets Pydroid 3 build any library from pip, even if it is using native code. You can also build & install dependencies from a command line.
- Cython support.
- PDB debugger with breakpoints and watches.
- Kivy graphical library with a shiny new SDL2 backend.
- PyQt5 support available in Quick Install repository along with matplotlib PyQt5 support with no extra code required.
- Matplotlib Kivy support available in Quick Install repository.
- pygame_sdl2 support (SDL2-based pygame implementation).

Editor features:
- Code prediction, auto indentation and real time code analysis just like in any real IDE. *
- Extended keyboard bar with all symbols you need to program in Python.
- Syntax highlighting & themes.
- Tabs.
- Enhanced code navigation with interactive assignment/definition gotos.
- One click share on Pastebin.

* Features marked by asterisk are available in Premium version only.

Quick manual.
Pydroid 3 requires at least 200MB free internal memory. 220MB+ is recommended. More if you are using heavy libraries such as scipy.
To run debug place breakpoint(s) clicking on the line number.
Kivy is detected with “import kivy”, “from kivy“ or "#Pydroid run kivy”.
PyQt5 is detected with “import PyQt5”, “from PyQt5“ or "#Pydroid run qt”.
The same for sdl2, tkinter and pygame.
There is a special mode "#Pydroid run terminal" to ensure your program runs in terminal mode (this is useful with matplotlib that automatically runs in GUI mode)

Take a part in development of Pydroid 3 by reporting bugs or providing feature requests to us. We appreciate that.

The list of libraries we are NOT planning to add yet:
- Tensorflow
- OpenCV

As Pydroid 3 main goal is to help user learn Python 3 programming language, our first priority is porting scientific libraries (so system-related libraries are ported only when they are used as dependencies of some other educational package).

Important notice:
Some users experienced major problems when installing libraries from QPython 3 QPypi internal repository, so consider it to be binary incompatible with Pydroid 3. If you need any libraries that cannot be built with Pydroid 3 - contact the devs directly: other binary repositories are likely to be incompatible as well.

Legal information.
Some binaries in Pydroid 3 APK are licensed under (L)GPL, email us for the source code.
GPL pure Python libraries bundled with Pydroid 3 are considered to be coming in the source code form already.
Pydroid 3 doesn’t bundle any GPL-licensed native modules to avoid automatic import of them. The famous example of such library is GNU readline, that can be installed using pip.
