VAGUS® breathe test for health advice (free) and VAGUS® NFT (V-NFT) minting (in-app purchase)

• Visualization of your breathing
• How your breathing affects your pulse
• Free health analytics and monitoring
• Track how your habits or diet are changing your stress
• The VAGUS® test is simple and quick: Perform controlled breathing during a 30 seconds ECG recording.
• Get real ownership of your smartwatch data with VAGUS® NFTs (in-app purchase).
• The app is free and it does not contain ads.

Use the apps advice to improve breathing, reduce stress and gain a better understanding of how food, drink or sleep is influencing your cardiac/respiratory health. This is the first-ever app to show the users exact breathe flow and the breathing induced pulse variation (HRV) - generated from your smartwatch ECG signal. The test lasts only 30 seconds. Breathe Flow is not a usual breathing advisory app. It shows your real breathing and it teaches you how to do controlled breathing with the ‘VAGUS® ideal breathing curve’.
With this app we launch the V-NFT concept, which is a new way to enable user ownership of smartwatch data.
Apple- and Withings smartwatches that has ECG.
• Open your smartwatch ECG recording app (Apple Watches; “ECG app”, Withings; ‘Health Mate’).
• Start by inhaling calmly for 5 seconds, then exhale for 5 sec. Continue this breathing pattern for 30 seconds (3 cycles of controlled breathing).
• ECG quality improves when you sit by a table. Hold your hands and elbows on the table. Let your breathing and pulse calm down before doing the test. Follow the smartwatch instructions and test again if the ECG recording is bad.
• Swipe down on the Breathe Flow home screen to activate download and analysis.
• Wait for about 10 seconds until analysis appears on the Breathe Flow app. Swipe down again to update the Breathe Flow screen. (Time delay depends on network speed)
• Answer the Q&A in English to receive a summary analysis and unlock Breathe Pulse.
• We recommend doing at least three BREATHE FLOW tests daily to learn how your actions impact your health and to collect high-quality data for your V-NFT.
For Apple Watch use, this app is integrated with Apple Health Kit. Activate your Apple watch on Health Kit before using this app.
For Withings watches this app is integrated with Withings Health Mate. Keep it active in the background while using Breathe Flow.
VAGUS® non fungible tokens (V-NFT) are standardized ring-fenced and anonymized data packages, each consisting of 10 unique days of VAGUS® tests, your Q&A text, other data from your smartwatch and data generated by VAGUS® analytics. We will automatically register a V-NFT when you have done at least 10 days of testing. These V-NFTs are your property and you may later sell them or gain a financial reward when their data is used on the VAGUS® Data Exchange. We plan for the V-NFTs to be publicly traded on exchanges such as Binance and VAGUS® Data Exchange.
A substantial part of the V-NFT raw data consists of VAGUS® Analytics data. The V-NFTs have a 'quality' label assigned to them which is contributing to the value of your V-NFT.
This is one of the most cutting-edge ways I’ve ever seen to know how your nervous system is really doing – far more promise than even Heart Rate Variability, which was the gold standard.
