dbLatex Little es a powerful and flexibleequations editor that allows to edit simultaneously the image ofthe equation and the corresponging latex code. It has a very amplelist of math symbols, from the most common ones to the veryinfrequently used. The use has a lot of facilities to organize thesymbols 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 theequation's name, the science that it belongs to, the speciality,the subject as well as extra info such as as, for example, a linkto web pages that give additional data about it. On this way onecan 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 isthe graphic, here it is paid more attention to the latex code ( aminimal knowledge of latex is highly recommended, but notimprescindible) that represent the equation because that is what aprofesional is going to need more often when he has to include enequation in scientific papers (full latex documents from which apdf is generated) or in blog entries in systems such as wordpress,blogspot (if mathjax, or similar plugin, is present) or forums thathave latex functionalities enabled. With the purpose of simplifyingat maximum the inclusion of the equations in this places the appincludes dedicated buttons that copy the latex code of the equationto the clipboard (without need of select it in the text box) andalso add the symbols required for the visualization of theequation.That is, if, for example, the equation is H\Psi= \lambda \Psi(Schroëdinger equation) and we push the wordpress button, theequation will be wrapped with the corresponding symbols and it willresult in $latex H\Psi= \lambda \Psi $, and, simultaneously, thattexto will be copied to the clipboard so that one in wordpress oneonly needs to paste the code.Of course the equations images also can be saved, or shared touse with other applications installed in the devices (whatsapp,facebook, gmail, dropbox, etc). For that it is enough to push overthe image and a contextual menu will appear with the affordmentioned options.If instead of using the included editor one choose to usemyscript smart note (or has been using it and has a lot ofequations created there)https://play.google.com/store/apps/details?id=com.myscript.smartnote&hl=esone can import the latex code of the equations created with thatprogram, one by one ,or all of a sheet at once.In many practical cases one will want to use deblatex andsimultaneously other applications, such as some pdf/djvu documentsreader, a web navigator, or the dedicated applications of wordpressor blogspot. If you are using dbLatex in a device belonging to thenote gamma (phablet, or tablets) one will be able to make use ofthe multiwindow functionalities and use dblatex and the otherequations side by side in the same screen.In the complete version of the aplication (available soon) thereare some very powerful extra features such as high definition graphfor the box with the math symbols, exporting sets of the savedregisters in a dsv, dollar separated values, file that allows usersto share the equations in their agenda among all his devices,executing the application, or with other users. There is also theoption to open a latex file (normally ay field in the arxiv has theoption to download the corresponding latex file), detect theequation's in it, show them in a combo box, and search in the opentext the context in which the equations appear.
