A few weeks ago, the Salzburger Nachrichten ran a story about my fuel price app. I woke up to more messages than I could count. Readers had either newly discovered the app, existing users asked what was coming next, and others simply wanted to say thanks. It was one of those mornings that reminds you why you build things in the first place.

The article, Er hat die Spritpreise genau im Blick from April 14, 2026, is embedded below for reference.

At that point, we were talking about my apps Spritpreise Österreich and Spritpreise Deutschland. I also mentioned that a unified European app, Petroly, was coming. I said May as a rough target. I was trying to be realistic.

Bitcoin Monitor

I created a little app for comparing cryptocurrency prices from Kraken, Coinbase, GDAX, Bitfinex, Bitstamp, Bitpanda & Coinfinity! It has support for Bitcoin, Ethereum, Bitcoin Cash & Litecoin with real-time exchange rates in Euro, Dollar & GBP. Make the best buy decision with real-time monitoring of Bitcoin prices across exchanges, visualization, lowest price detection, arbitrage potential calculation, change & volatility monitor and performance check between cryptocurrencies (BTC, ETH, BCH, LTC) with prices for €, $ and £.
