## Description

Exec Lua is a powerful development environment and runtime for Lua scripting on Android devices.

## Review summary

Exec Lua is a stable and functional mobile Lua IDE especially useful for beginners due to its error highlighting and sample code, running Lua scripts smoothly on Android devices. However, it lacks support for interactive input functions, does not have features like undo/redo or dark mode, and faces UI challenges like toolbar visibility and execution button placement. Crashes on some Android versions and absence of advanced features reduce its overall usability, but the app is appreciated for its simplicity and ease of use without ads.

### Pros

- Runs Lua code effectively on mobile devices with a simple, clean interface.
- Stable and functional with proper output and fast execution.
- Does not have distracting ads, making the learning experience smooth.
- Includes some sample code to get started.

### Cons

- Input functions like io.read() do not work, limiting interactive input.
- Lacks common features like undo/redo buttons and dark mode.
- UI issues such as toolbar hiding unexpectedly and execution button placement obstructed by the keyboard.
- Crashes reported on certain Android versions like Oreo.
- Limited feature set with missing advanced features like command line or git support.
