## About ApexCalc

ApexCalc is a free web platform that gathers calculators across more than 50 disciplines, including medicine, engineering, finance, science, law, and sports and fitness. The site lists over 11,600 tools, which can be searched or browsed by category and opened in the browser without signing up or installing anything.

Each calculator opens on its own page. The site says its tools include formula logic, sourced citations and links to related tools. It also lists regional finance, tax, mortgage and legal tools for 150 countries, alongside everyday calculators such as BMI and mortgage tools.

The platform is aimed at students, professionals and anyone who needs a quick answer in a specific field. The site states that every calculator is free with no account required. It also describes paid tiers for saved bookmarks, PDF export and API access, but these are marked as coming soon and are not yet available.

## About Xue Chinese

Xue Chinese is a Mandarin learning app for iPhone, iPad and Android. Its original HSK 3.0-aligned lessons connect vocabulary and grammar with everyday dialogues, listening, reading, quizzes and practice assessments.

Follow a guided learning path and revisit completed material. Try the first unit of any available level free; optional monthly and yearly Pro subscriptions unlock paid units and level assessments. The website provides curriculum information, study guides and support. Xue Chinese is an independent resource; its practice questions and in-app graduation assessments are not official HSK papers or certificates, and it does not guarantee exam results.
