one sec – break your social media habits

“one sec” uses Shortcuts Automation to toggle a deep breath animation whenever you open one of the configured apps (Instagram, Twitter, YouTube…). This breaks unconcious social media habits and even helps long-term by adding more friction when opening these apps. Breaks unconcious social media habits Being forced to take a deep breath helps yourself to reflect on what you are currently doing on your phone – did you really want to open Instagram or was it muscle memory?

Setting up QuickScreen

QuickScreen mirrors your phone‘s screen quickly to your Mac. Even though the user interface is super-simple (and quick!), there are a couple of things you can try if your phone does not connect somehow: Launch QuickScreen on your Mac. Make sure your iPhone is connected with a lightning USB cable to your computer. Newer iPads are connected with a USB-C cable. Make sure that you allow your computer to access your phone (there might be a pop up on your phone to “trust this computer”).

Processing for iOS Education Challenge 2019

Submit your coolest projects, stories, and course material around Processing for iOS! I’ve started my app “Processing for iOS” as a little side-project in 2011. I wanted to have my processing sketches always with me to show my friends or to code on the go on my iPod Touch. At some point, I figured out that other people were also interested in using my app, so I decided to upload it to the AppStore in 2012.

Hackathon Stuttgart 2014: MealHub

MealHub was our project at the Hackathon Stuttgart 2014. We developed this app to be able to meet new people, cook and eat together. The initial problem was the lack of lunch options at our university. But what if every dorm could be a canteen? Cooking for five people is not much more time-consuming than cooking for one or two. After all we received the “price for best project”. After winning the hackathon we decided to continue working on MealHub and release the app on market.
