Ezequiel Santos

Apple Platforms Developer

Hi, I am Ezequiel.

I started with technology through mechatronics in 2007, then learned iOS development at the Apple Developer Academy in 2013. I still make small, useful software for Apple platforms. Some are for work; many exist because I wanted them to.

Apps for academic work.

During my master’s and now my PhD, I have built small apps for the academic problems I encounter.

  1. Your citation profile

    Citatum is the neuter form of citatus in Latin, meaning something cited. The name keeps the focus on the work being cited and the record that grows around it.

    Citatum

    • iPhone
    • iPad
    • Mac

    Keep a quiet eye on your citations, h-index, i10-index, and the publications receiving attention, without repeatedly checking Scholar.

  2. Your publishing pipeline

    Auctorium is Latin for a supplement to a body of work. That idea shapes the product: a calm layer that adds structure and context without stealing focus from the research itself.

    Auctorium

    • iPhone
    • iPad
    • Mac

    Move every paper from first idea to published work, with venues, submission states, deadlines, reminders, and the next decision in view.

  3. Your reference library

    Repertum is the neuter form of repertus in Latin, meaning something found or discovered. It suits a library built around finding, collecting, and returning to sources.

    Repertum

    • iPad
    • Mac

    Turn DOI, PMID, arXiv, HAL, and GitHub identifiers into an organised, editable citation library that stays in sync across Mac and iPad.

  4. Your academic opportunities

    Opportunum is the neuter form of opportunus in Latin, meaning something suitable, favourable, or timely. It reflects an opportunity that arrives at the right moment.

    Opportunum

    • iPhone
    • iPad

    Discover academic positions, scholarships, grants, and calls that match where your research is heading, then save the ones worth pursuing.
