The Photerest Studios create and publish iPhone and iPad apps. Our focus is photography apps around Instagram. By now, we've published five apps (PreGram, Hashtags By PreGram, Fun Photo Factory, Professor's Daily Tips for Excel and Professor's Error Helper for Excel).
With a consulting background, our recent project is "Professor Excel". A platform built around Microsoft Excel with an extensive knowledge area, downloads and the Excel add-in Professor Excel Tools.
The Photerest Studios are based in Hamburg, Germany.
