What it does
Most calorie calculators give you a number with no context. MacroDeficit gives you three connected tools that actually help you act on the result. The TDEE calculator finds your maintenance calories and breaks down exact macro targets for your goal: cut, lean bulk, aggressive bulk, or maintain.

With social media and now AI, its important to keep the indie web alive. There are many people who write frequently. Blogosphere tries to highlight them by fetching the recent posts from personal blogs across many categories. There are two versions: Minimal (HN-inspired, fast, static): https://text.blogosphere.app/ Non-minimal: https://blogosphere.app/ If you don't find your blog (or your favorite ones), please add them. I will review and approve it.
