Leon Hartmann is a freelance journalist and iGaming analyst based in the United Kingdom, specialising in mobile casino app reviews. He studied Media and Communication at the University of Leeds, graduating in 2012. From 2013 onwards, he built his career as a sports journalist, covering football for regional media before moving to national outlets where he reported on Premier League matches, European club competitions, and major international tournaments. Over more than a decade in sports media, he developed a structured approach to research, fact-checking, and analytical reporting. In 2023, Leon shifted his professional focus to the online gambling industry, driven by the rapid growth of mobile casino platforms and a genuine interest in how operators deliver — or fail to deliver — a quality experience to players. Since then, he has conducted extensive hands-on reviews of casino apps for Android and iOS, evaluating interface design, bonus structures, payment systems, licensing standards, and responsible gambling features. His review methodology is player-first and transparent: every app is tested personally, with real account registration and deposit flows tested where applicable. He cross-references operator claims against regulatory data and independent sources to ensure every published assessment is accurate and reliable. Leon currently works as a senior freelance journalist and industry analyst, publishing in-depth casino app reviews for players in the UK and European markets.
