Ten years ago, on June 10 2008 Apple started the AppStore. With only a few hundred apps in the beginning it’s amazing to see to what it has grown today. Fantastic indie careers have been kicked off thanks to the AppStore. Many new startups are only successful because of the power of the AppStore. On this historical day, I decided to tell my personal AppStore story. This is about how I started to develop apps with iRedstone: https://twitter.com/frederikRiedel/status/1016751745773555714 And some other developers started to share their stories as well. Amazing, interesting, hilarious, personal, funny things. I hope that this shows everyone else that there are no magic skills required to create impressing apps. And that releasing an imperfect app in the[…]

Today I am publishing a new app on the AppStore: This time I combined two of my passions: My passion for climbing & bouldering and my passion for iOS development. iRedpoint iRedpoint is a fitness tracker for bouldering and climbing that uses the built-in sensors form the Apple Watch. While I developed this app I discovered how amazing and well-thought watchOS and the actual Apple Watch hardware already are – providing computing power for real-time machine learning analysis of accelerometer and gyroscope samples, the heart rate and the barometer. iRedpoint features an iPhone companion app as well that analyzes and visualizes the training data. This includes personalized training feedback and detailed charts. You can download the app for free on[…]

At this year’s Funk Hackathon in Mainz we developed a platform to organise and participate in protests all around the world. This platform helps to strengthen the democracy we live in by bringing together organisers and participants for protests against right-wing ideology, nationalism or for animal’s rights. In the last couple years, young people have often been accused of not being political. A generation where political activism equals clicktivism or slacktivism that remains digital, but fails to show visible dissatisfaction with policies on the streets. The visibility of the moderate majority in our societies has been overshadowed by populists, who have been able to make pan-European connections both in their protests and their communication campaigns. However, with Brexit and Trump as painful[…]

This year’s Hackathon Stuttgart took place in the beautiful Römercastel location in Bad Cannstatt. This is a huge building with plenty of places to work and sleep at night. This hackathon is organized by logicline. The Idea When it comes to hackathons I am always a fan of crazy projects you wouldn’t or cannot do at home. In this case we were interested in Car2Go and Kärcher (which is a German company producing machines and equipment for cleaning) – both provided interesting hardware for the event. Car2Go had different versions of their cars and Kärcher had a street sweeper. After looking at the different APIs we chose the street sweeper to work with because it just provides more capabilities. It has multiple sensors and interfaces to[…]

Ferienakademie is a voluntary holiday academy organized by three Universities from southern Germany: Freie Friedrich-Alexander University of Erlangen-Nürnberg (FAU), Technical University of Munich (TUM) and University of Stuttgart. It takes place in Sarntal, which is a beautiful high valley near to Bozen in Italy. This year I participated in Bernd Brügge’s and Daniel Siewiorek’s course “Cyber Physical Systems”. We built a system which can help workers in extreme environments to minimize risks and to identify hazards earlier. Our system creates a local peer-to-peer mesh-network which ca transfer sensor data from so-called “emergency beacons”. These beacons can be deployed by specially-equiped workers, or from a drone. This can help to collect important environmental data in hazardous environments. Sensors can measure radioactivity, heat, oxygen levels and other essential values. The autonomous drone is[…]

SoPra (software practical) is part of my Bachelor program “Software Engineering” at the department of our Professor Stefan Wagner. Together with two other students I had to realize a software project within one semester. This year’s assignment was to create a Java-tool that supports tournaments for card-based games. But developing the tool was not everything – like in a real software-projects different documents like an offer, specification, system draft, project plan, test protocol needed to be created. Our team consisted of Larissa Laich, Josef Mair and me. Naming our Product Our software is named “NICHTS” (which means “NOTHING” in German) and stands for “Neue innovative clevere hilfreiche Turnier-Software” (“New innovative clever helpful tournament software”). The naming of a product is very important – people will remember the name when they[…]

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. We worked on a server infrastructure, that organizes and exchanges events between participants, an iOS app and an Android app. After several months of work, customer interviews and business studies we were able to release the app. Mache Essen und Kochen[…]

We developed an app which helps to collect donations for charity by running. People who participate pledge a certain amount of money for every mile you run which is then automatically collected and donated to the charity organization. You can select from different charity organizations manually who should receive the donations which are collected by your running activity.  

In 2013 we published the first app-version for Leinfelden-Echterdingen’s annual “Krautfest”. The festival is visited by more than 100’000 visitors on one weekend. The new app also contains a bus-tracking feature, which shows the location of the Krautfest-bus-shuttles live on a map – that’s a brand-new feature which isn’t even available in the official VVS app! We presented the app at the press conference last week. The app is available for iOS and Android. Read more about our app here: Vereinsring Echterdingen, Stadt Leinfelden-Echterdingen, Leinfelden-Echterdingen, Stuttgarter Zeitung, Amtsblatt

At IBM’s bluemix hackathon we developed an iPhone app with intelligent weather capabilities: The app can wake you up earlier when harsh weather conditions occur (for instance snow). It is also able to warn you before certain weather conditions appear using the weather forecast. All calculations are done on IBM’s bluemix backend system, which then sends out a push notification to our fronted iPhone app. Read more about the hackathon and our project on IBM’s website. After all we were rewarded with the first price for our project.

A single restaurant can have thousands of reviews. Way too much noise to actually get exactly what you may want. At Reviewily we help organize the reviews, ratings, and comments so you can dive directly into what you care about, what people mention a lot, and you can be a more informed customer. Using IDOLOnDemand API (Sentiment Analysis) we pin point specific topics people people care about when reading reviews & comments. We can detail how many positive and negative comments a topic generates. Thus, a better way to understand a restaurant or a product than just the 5 star rating system. We won the second price at this hackathon.  

We’re proud to announce that our app “iRedstone” for iOS, Android and Mac OS has been downloaded more than 1 million times! At the same time we reached another milestone: iRedstone is among the top five most downloaded apps in Germany – being downloaded more often than Doodle Jump! iRedstone has been featured on television, watch the excerpt here:

Today we’re proud to announce that our app “iRedstone” has been released by Apple’s review team on the iTunes AppStore and is available for iPhone and iPod Touch. iRedstone contains many instructions which are related to the redstone-electronics within the popular computer-game “Minecraft”. Redstone is not simple to learn, so we created this app to help everyone who’s interested to learn the basics. If you want to submit your own instructions you can do it here: add.my.instructions@gmail.com

This is a school project I have been working on for half a year. QBe is a clone of the popular game “Minecraft“, written using Processing.org. Minecraft is like virtual Lego, you can place blocks, remove blocks and explore your personal world. Mountains, lakes, trees and caves are automatically created by a landscape-generator. We started this project in winter 2011 for school. This is a picture of a early test version of our game: And this is how the finished version looks like:
