TeXpert
As an integrated environment, TeXpert allows users to edit, compile (generate PDF output) and view the result within a single app. As a result, it provides the convenience and productivity because it eliminates the hassles of switching back and forth between different applications. In this context, one does not have to open, say TeXPortal, to (re)compile the document and wait for it to complete then open generated PDF with another app; finally using Android's Recent apps button to go back to continue editing the file. The user interface is designed with usability optimization purpose. For instance, scrollbar is added for fast scrolling through the document.
Syntax and Mathematics Highlighting TeXpert provides fast syntax highlighting with little lagging. Noteworthy capability is mathematical formula highlighting, a feature rarely provided by editors. Even on PC, only TeX Maker seems to provide that capability. LaTeX Specific Beyond that, TeXpert understands LaTeX unlike general purpose text editors. It offers easy access to frequently used symbols in LaTeX documents such as dollar and backslash, hierarchical document outline (i.e. \chapter , \section , \subsection , etc.; Version 2.3.2 goes a step further by considering beamer frame 's.), annotated log, etc. These features facilitate much better navigation because writer usually works on organizational units and also help in debugging process. TeXpert intends to provide smart completion and other editing enhancing features in the future.
