dbLatex es a powerful and flexible equations editor that allows to edit simultaneously the image of the equation and the corresponging latex code. It has a very ample list of math symbols, from the most common ones to the very infrequently used. The use has a lot of facilities to organize the symbols in the screen to find the way that better fits it's needs.
Once created an equation this can be saved in a database, together with fields with additional information such as the equation's name, the science that it belongs to, the speciality, the subject as well as extra info such as as, for example, a link to web pages that give additional data about it. On this way one can have an equation's agenda of the most commonly used equations, and make a search for them in function of the diverse fields.
Contrary to other equation's editor , where the main focus is the graphic, here it is paid more attention to the latex code ( a minimal knowledge of latex is highly recommended, but not imprescindible) that represent the equation because that is what a profesional is going to need more often when he has to include en equation in scientific papers (full latex documents from which a pdf is generated) or in blog entries in systems such as wordpress, blogspot (if mathjax, or similar plugin, is present) or forums that have latex functionalities enabled. With the purpose of simplifying at maximum the inclusion of the equations in this places the app includes dedicated buttons that copy the latex code of the equation to the clipboard (without need of select it in the text box) and also add the symbols required for the visualization of the equation.
That is, if, for example, the equation is H\Psi= \lambda \Psi (Schroëdinger equation) and we push the wordpress button, the equation will be wrapped with the corresponding symbols and it will result in $latex H\Psi= \lambda \Psi $, and, simultaneously, that texto will be copied to the clipboard so that one in wordpress one only needs to paste the code.
Of course the equations images also can be saved, or shared to use with other applications installed in the devices (whatsapp, facebook, gmail, dropbox, etc). For that it is enough to push over the image and a contextual menu will appear with the afford mentioned options.
If instead of using the included editor one choose to use myscript smart note (or has been using it and has a lot of equations created there) https://play.google.com/store/apps/details?id=com.myscript.smartnote&hl=es one can import the latex code of the equations created with that program, one by one ,or all of a sheet at once.
In many practical cases one will want to use deblatex and simultaneously other applications, such as some pdf/djvu documents reader, a web navigator, or the dedicated applications of wordpress or blogspot. If you are using dbLatex in a device belonging to the note gamma (phablet, or tablets) one will be able to make use of the multiwindow functionalities and use dblatex and the other equations side by side in the same screen.
In the complete version of the aplication there are some very powerful extra features such as high definition graph for the box with the math symbols, exporting sets of the saved registers in a dsv, dollar separated values, file that allows users to share the equations in their agenda among all his devices, executing the application, or with other users. There is also the option to open a latex file (normally ay field in the arxiv has the option to download the corresponding latex file), detect the equation's in it, show them in a combo box, and search in the open text the context in which the equations appear.
Added nuew formats and qualities of the equation image in the editor.
Now you can past the latex code to the clipboard directly from the editor.
