Here are the projects I'm currently working on:

Fire Chicken Webring (2023 – Present)

An invite-only webring for personal websites.

HomeMatic ChurchTools Plugin (2023 – Present)

This project connects the smart home system HomeMatic to the church organization tool ChurchTools, exposing a virtual remote that toggles if an even in a ChurchTools room started or stopped.

This allows administrators to control their heating and other appliances only when needed, saving energy and time.

It’s currently in the early-access phase so @ me if you want to give it a try. (2022 – Present)

I’m running a Mastodon instance for friends together with Jan. Hosted on Ossrox.

Arne’s Weekly (2021 – Present)

Sprachnachrichten (2020 – 2023)

A podcast I did with my good friend Jan in German. We talked about tech and productivity, our side projects, our home screens and once a year held a gala to select the best apps, music and more.

If you want to get started, I recommend one of these episodes:

ing-ynab (2020 – 2022)

An application which allowed you to automatically import ING Germany bank statemenets into YNAB via FinTS.

I abandoned it when YNAB added the functionality in their app, even though ing-ynab handled PayPal transactions better.

Widgets for YNAB (2020 – 2021)

An app which allowed you to display the balance of one to four of your YNAB categories in an iOS widget.

COVIDget (2020 – 2020)

An iOS app I wrote to play around with widgets when they were new in iOS 14. It allowed you to select a German district and would automatically fetch the recent numbers and show them in grey, orange or red, depending how big the number is.

I submitted it to the App Store but got rejected because of a rule that says I can only use data of my own service, not directly call the RKI (The German federal government agency responsible for disease control and prevention).
