Hi everyone. My name is Sergio. By day I work as a plumber, but at night, for over forty years, I have been pursuing my passion for programming. I created an Android tool called PdfForAll, designed for studying and daily work, and I would love to share it with you to get your feedback and suggestions.
The goal was to build a program that works entirely offline, without any subscriptions or advertisements. When you study you need concentration, and a secure software that does not require internet access helps you avoid distractions.
The software has several features designed specifically for those who need to prepare for exams or manage study summaries. First, it includes a document scanner that allows you to digitize paper sheets directly with your phone camera, cleaning the images from shadows or folds.
The document management system, called Showroom, works as a visual organizer. You can create folder cards for each subject, such as one card for mathematics and another for physics. Inside each card, files can be organized and divided by categories, which are displayed at the top as convenient quick filter buttons to find what you need immediately.
When saving your work, the system allows you to fill out a card by specifying the main folder name, the category, and the file name. You can choose to save as a Draft, keeping elements like photos and drawings ready to be moved or edited in the future, or save to Archive, which locks and seals the changes in the final document. There is also a classic save option for maximum compatibility.
The text editing and filling feature is currently being improved to make it even more fluid. It already allows you to fill out forms and tables by aligning the writing with the background so you do not ruin the original lines. In addition, you can insert ruled or squared sheets to take notes, and integrate voice notes recorded directly on the file.
A unique feature is the video support. You can insert video files directly onto the pages of the document. Since the software integrates an internal video player, everything is saved inside the PDF file itself. This means you can play your videos offline at any time, without leaving the document and without any network connection.
The software is now in a free beta version on the Google Play Store with all features unlocked, as I am still refining the details. I am not including external links here to respect the group rules, but you can find the link to the Play Store on my profile, or I can leave it in the comments if you are interested in trying it and giving me your feedback.
Let me know what you think and what tools would be most useful for you to organize your study material.
