Explain the evidence
When relevant, guides and calculator methodology sections link to research, reference laboratories, and public-health organizations so you can explore the source material.
HealthCompass365 · About us
HealthCompass365 is an independent educational website built around a simple idea: health information should be understandable, practical, and honest about uncertainty. We bring together free calculators and approachable guides so you can explore everyday health questions with more context.

Our story
Health questions often come with complicated terminology, conflicting advice, and numbers that need context. This site aims to make that first step easier.
We create interactive educational tools and plain-language guides about wellness and everyday health questions. The goal is to help you understand concepts such as how a calculator works, what a screening result means, or why estimates can vary between people.
You can explore the resources at your own pace, without creating an account.
We believe a useful health resource should describe its assumptions, make uncertainty clear, and point readers toward further information. A calculator can be a starting point for learning—but should never pretend to know more than its inputs and evidence allow.
That perspective shapes the tools and articles we're building.
How we approach content
These are the principles we aim to follow as HealthCompass365 grows.
When relevant, guides and calculator methodology sections link to research, reference laboratories, and public-health organizations so you can explore the source material.
Individual biology, test methods, and real-world circumstances can differ from simplified examples. We try to explain those limitations rather than promise certainty.
Our calculators are designed to be easy to use, with plain-language labels and explanations alongside estimated results.
Depending on the topic, our articles and tools may refer to published studies, government health resources, professional guidance, and laboratory references. Sources and calculation methods are provided on individual pages where appropriate.
Scientific understanding and guidance can change. Readers should consult the linked references and relevant professionals for questions that require up-to-date or individualized answers.
HealthCompass365 does not provide medical diagnosis, treatment, legal advice, or a guarantee about a drug test result. Tools such as caffeine estimates, calorie calculators, and THC detection examples are simplified educational models, not personal measurements.
For health concerns or decisions with important consequences, consult a qualified professional and the relevant testing or healthcare provider.
