## 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 StepGenie

StepGenie is a question bank for USMLE Step 1, Step 2 CK and Step 3 preparation. Its explanations are built mostly from images rather than long text. Step-by-step images walk through a concept one idea at a time, comprehensive images summarize a whole topic on one screen for revision, and distractor images explain why each wrong answer does not fit. The site lists more than 10,000 NBME-style questions in its Visual QBank and more than 5,000 keyword-combination questions in a separate Pattern Mastery QBank.

The platform also includes a flashcard library of over 20,000 cards using the FSRS spaced repetition algorithm, with cards that sync to questions a user has missed. An Ask AI feature lets users question an explanation in a chat, for example asking why a specific diagnosis was not the answer, and receive a follow-up explanation. Users can track retention rates and due cards in a dashboard and can filter custom decks by tag.

The product is aimed at medical students preparing for USMLE exams. The site offers a free plan with daily limits on questions, and paid plans that include the full Visual QBank and Pattern Mastery QBank with performance and knowledge gap analysis. The site is available in a mobile browser, with no native app listed.
