(Open Source) MVG is Munich’s public transport organization. While they have a pretty good app, I found it to require a bit too many taps to get live departure times for a favorite station. With my website, one can add a station as a browser bookmark (or add to the Home Screen) and get the departure times with a single tap. Also, one can filter by individual lines (which is not possible in the official apps).
(Open Source) Our son would often wake up very early, thinking that the day begun. With the sleeptrainer website - running on an iPad with an always-on display - he can see from the current color if it is already time to rise or not. There exist several similar sleeptrainer devices, but none of them convinced us, especially because none of the devices had a “yellow” time slot, which would signalize that time to rise is near. Neat feature: This is a PWA (progressive web app) - when added to the home screen, it will also work offline!
(Open Source) During my paternity leave, I visited some courses at Fabi, an organization dedicated to provide courses to families. I found browsing the courses a bit cumbersome, so I created a script that crawls their website daily & provides the courses as a simple table with instant search & filtering capabilities.
(Open Source) As part of a previous job, I often organized tech workshops & talks. I made livetext to share code and other text snippets with my participants in real time. Code, links, quotes, images - basically anything that can be expressed with Markdown.
For the pregnancy time with our first child, I created a baby countdown website. With Days Until Baby, now everyone can create their own personal countdown website. As website & app, to share with friends and family.
Jealous of PowerPoint productivity add-ons like think-cell and empower slides that are used by consultants and other professionals all around the world? PowerPack brings these features to Google Slides. Over 40,000 installs.
(Open Source) When some of my friends were moving to Munich (& Germany), I created a website with information around living here - essentialmunich.de
