Vivoo

Eight markers from one strip: water, pH, calcium, magnesium, vitamin C, sodium, oxidative stress and ketones. Each one comes back with its own score, and the app combines them into an overall wellness score out of ten.

Ninety seconds. You download the free Vivoo app, take the strip out of its pouch, urinate on it, wait 90 seconds, then scan the strip with your phone camera. The app reads the colour pads and returns your scores along with nutrition and lifestyle suggestions.

No. Vivoo is a wellness test, not a medical device, and it is not intended to diagnose, treat, cure or prevent any disease or condition. It does not replace a laboratory urinalysis or medical advice. If a result worries you, or you have symptoms, see your doctor or talk to our pharmacy team.

No. The Vivoo app is free to download on iOS and Android, and the tests sold here are one-off purchases. You buy strips, not a plan.

Buy the single if you want to see what the app does before committing. Buy the four pack if you already know you want to track something, because Vivoo is designed around one test a week and four tests is a month of that. A single reading tells you where you are today; four tell you which way you are heading, which is the point of scoring eight markers at once.

The strip is read by the app's camera rather than by eye, which takes the guesswork out of matching colours to a chart and removes the effect of your bathroom lighting. That said, it is a screening tool for wellness markers, not a laboratory urinalysis, and it is not calibrated to clinical thresholds.

Yes. Vivoo says antibiotics, diuretics, neuroleptic medicines, painkillers and hormonal medicines can all affect the reading, and that results may be altered during pregnancy. If you are on any of those, treat the numbers as rough and talk to your doctor or our pharmacy team before reading anything into them.

Vivoo gives the strips an 18 month shelf life from manufacture, and the expiry date is printed on the pack. Keep the pouch sealed until you are ready, because the pads are sensitive to air: once you open it, use the strip within five minutes.
