Frequently asked questions

Easily add your lab results either manually, by uploading a PDF, or by scanning your report with your camera. Node Health reads your values, places them within personalized reference ranges, and shows you what's in range and how your results are trending over time.

The app is ideal if you want to proactively manage your health. It's perfect for data-conscious individuals who want to understand their biomarkers, as well as track and optimize them. You can also use the app to prepare for doctor visits and facilitate data-driven discussions with healthcare professionals.

Currently, we support all iOS devices, with development of a tailored iPad version ongoing. Unfortunately, we do not yet support Android.

The Node Health app is free and available on the iOS App Store. Core logging and tracking features are free, while certain premium features — such as our AI upload feature — require Node Health Plus.

All your data is encrypted and stored directly on your smartphone. When you delete the app, your data is deleted as well. We do not store any of your personal data on our servers.

During AI processing, your data is anonymized and sent to our AI provider for biomarker matching. Your data is deleted immediately after processing and is not used for training purposes.

Yes, you can export your data at any time directly within the app — for example, to keep for yourself or transfer to a new phone.

We do not store your personal data on our servers. However, if you have iCloud backup enabled, your biomarker data is usually saved. To restore it, you will need to install the app from a backup rather than installing it fresh.

Please note that since we do not have access to your personal data, we are unable to provide direct support in this case.

Using our PDF or scan upload feature, we support reports in almost all formats. Additionally, individual biomarkers can be added manually if a report isn't recognized. We're continuously improving extraction quality based on user feedback.

If you're missing a biomarker, please reach out — we'd be happy to look into it.

Since we place great importance on accuracy and reliability, we maintain our own biomarker database. Each new addition goes through a strict approval process by a medical professional. We do not rely on AI or other services to provide biomarker information; instead, we use established clinical sources (major European and US-based research institutes).

PDF formats vary widely between labs and can sometimes be difficult to parse. If a value is missing, you can add it manually in seconds. We use feedback from cases like this to improve recognition for all users.

We rely on established clinical sources (major European and US-based research institutes) for our standard reference ranges. It is important to compare these with your lab-specific ranges and customize them if necessary.

Where appropriate, reference ranges are personalized based on your age, sex, height, and life stage (e.g. pre/postmenopause). Node Health Plus also allows you to customize individual biomarker reference ranges to better suit your needs.

"Standard" reflects average values found in a general population sample in Western Europe. Being within this range is considered healthy and usually means your values align with typical trends.

"Optimal" is based on emerging research and wellness-focused studies. This range reflects levels associated with positive health outcomes. It is not a clinically standardized threshold and is intended as a wellness guideline rather than a medical reference.

It's important to always compare these ranges with those provided by your lab and consider your personal situation, as individual results may be influenced by many factors that population averages cannot account for.

Currently, our app does not provide specific health or medical recommendations. We place great importance on accuracy and reliability and remain cautious due to the sensitive nature of health-related advice.

However, we do provide basic information on where your values lie and what can be done to help keep them within a normal range. Please note that this information consists of publicly available sources tailored to your personal situation (e.g. gender, age). It's also important to understand that all information provided by the app does not constitute medical advice. We always recommend consulting healthcare professionals for personalized medical guidance before taking any specific action.

We love hearing from users. Reach out via the Contact section in the app or email us — we read everything, and many of our most-used features come directly from user requests.
