## 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 Submit Your Startup

Submit Your Startup is an open index where early-stage founders submit their products and have them listed in a daily launch board, presented as an evening edition. Founders paste a URL and the site sets the product type. Free launches wait their turn in a queue and go out in an assigned time slot.

Rank is set by votes alone. Each launch has 24 hours on the board, and new launches join the ranking after two hours. A paid option, listed at $9 for the next open slot, changes the time a launch goes out but not its rank.

The site also offers an email newsletter: a daily Evening Edition with the final board and a weekly review on Mondays. It lists an archive of past launches across categories such as AI, SaaS, Productivity, Fintech and Health.
