Wokabulary is a flash card learning app for iPhone, iPad, Mac, and Apple Watch . It helps you collect and practice your personal foreign language words and is a supplement to in-person language courses and language course apps.

For ten years, Wokabulary has been in the charts of educational apps in the Apple App Store. The current version has been re-written completely in Swift and SwiftUI and was released in Summer 2023.

Tincta is a text editor for the Mac. The intuitive editor can be used to write everyday notes and texts, but also contains all the functionalities for professional programming and web design.

Tincta is an open source project and can be used for free. Furthermore, the software is open for further development and reuse by other developers.

Despite or even because of digitalization, the importance of written communication is increasing. LanguageTool is your intelligent writing assistant that not only finds spelling mistakes. It also enriches your texts with helpful grammar and style suggestions in more than twenty languages.

Gabriel supports the LanguageTool team in the development of the Mac app. Especially important here is a native, performant implementation and seamless integration with other apps.

In all areas of work, decisions are important for the progress of projects and ideas. ideas. Especially now with hybrid work models and global teams. To facilitate collaborative and informed decision-making we have developed Loqbooq.

Loqbooq is a web application for easy and permanent logging and documentation of decisions in teams as well as with external partners and stakeholders. In order to integrate the decisions into the workflows and daily communication, there are also integrations for Slack and Webex in addition to the web app.

The real estate start-up HAUSGOLD significantly simplifies real estate sales for brokers and property owners. The iOS app is a tool that brings clients and brokers together and helps the latter to manage their activities. The iOS app is a tool that brings clients and realtors together and helps the latter to manage their activities.

Julius maintained and developed the iOS app for the Hamburg-based start-up. He re-implemented Objective-C components in Swift, fixed bugs, optimized loading and startup times and connected new APIs.

What's more important than a good night's sleep? To help everyone who is not blessed with it, the start-up sleep.ink sells natural sleep products and other products that help with relaxation.

We advised the start-up on the technical planning and supported them in the further development of their e-commerce system.

Music search is an exciting field of research and development with different approaches and encoding.

With IncipitSearch we have developed a portal for searching melodies in collections of classical music as part of a research project at the Academy of Sciences and Literature. It connects content from different music editions and libraries using metadata. The ontology Schema.org and the library standard Plaine & Easie Code serve as the underlying encoding to make the sheet music searchable.

Digitalization in science and research is taking place at many institutes and in various projects. The goal of the National Research Data Infrastructure, funded by the German Federal Ministry of Education and Research, is to bundle these different efforts.

Julius supported the development of an information portal for the Consortium for Research Data on Material and Immaterial Cultural Heritage (NFDI4Culture) with backend programming using TYPO3 and collaborated with a team of researchers and a digital agency.

Scientific collections and sources are not only published as multi-volume works, but also as digital editions. This is also true for the source collection on the history of German social policy and the emergence of the German welfare state at the University of Kassel. Anna has realized a digital edition in collaboration with other researchers and developers.

Tasks: Data processing and encoding as well as frontend and backend development with XML/XSLT, PHP, TYPO3.

Habit trackers help us keep track of our habits and “stick to it”. With UpMoji we have developed a tally counter app to track your own habits using emoji representation.

UpMoji is implemented completely in SwiftUI and is available for iPhone, iPad, and Apple Watch.

Team spirit is crucial to every work environment. But hybrid and remote teams don't meet accidentally at the coffee machine anymore. With Macarons we created a minimalistic coffee roulette app for Slack that automatically matches random team members for casual chat.

To get started, Macarons simply needs to be added to a Slack channel. Built-in icebreaker questions make for an easy conversation starter.

To admire architecture and glorious buildings directly on site is the most beautiful experience. This is true for tourist trips, but also for science, when spatial impressions or arrangements are significant for the interpretation of sources and actions. However, it is not always possible to be on site. Therefore, we have developed a generic software for virtual tours through cultural heritage sites.

One implementation is a virtual tour through the UNESCO World Heritage Site Hildesheim Cathedral. The tour provides information about history and furnishings of the church. Developed in the context of a research project of the Academy of Sciences and Literature, the tour was also shown as part of a museum exhibition.

When learning a language, direct exchange and active speaking of the foreign language is just as important as a pleasant learning environment.

Lernsalon e.V. in Halle is a space for language courses, learning support, celebrations, music, and culture. They offer English and Spanish language classes for adults, children, and companies.

We developed a new website as well as a management system for courses and clients for Lernsalon. The new site makes the different facetts of Lernsalon - language courses, cultural events, premises - equally visible and offers a convenient overview, administration and registration for the courses.

In cooperation with scientists of the institute, a multilingual virtual exhibition on Jewish emigration to South America in the 1930s was launched in 2022.
In January 2023 the portal Jüdisches Hamburg erzählen [Telling Jewish Hamburg] with life-historical interviews with Hamburg Jews was published. Under the maxim Presenting History – Depicting Diversity, it aims to illustrate the diversity of Jewish life in Hamburg since 1945.
