When is the Body Coach coming out?

Bisu Body Coach will be available for beta testing in 2019, and will go on sale in 2020.

What stage is the product at now?

We have a working prototype which is being optimized in preparation for the 2019 beta test. We are designing with mass manufacturing in mind so we can avoid shipping delays in 2020.

How can I become a beta tester?

How much will it cost?

While we can’t give a final price right now, our aim is to have the device cost no more than $150, with a cost of $1 per test stick. Each stick tests multiple biomarkers.

Where will you ship?

We will ship worldwide, but please note that support will initially be available in English only.



How are tests performed?

Tests are performed using a test stick consisting of a biodegradeable test chip mounted on a sliding rail with in a card cover. The chip is extended out of the casing using the sliding rail and the absorbent pad on the end dipped briefly into the stream of urine when using the toilet. The chip is retracted inside the casing using the same rail and the test stick then placed onto the test stick reader. The reader automatically wakes up, locks the test stick in place, performs the test (approx. 90 secs) and then releases the test stick for disposal. 

How often will I have to perform tests?

We generally recommend testing every 1-3 days. While testing less often will still be helpful, it will be harder to see your data move in response to changes in your diet and lifestyle.

When should I perform tests?

We generally recommend either testing first thing in the morning or in the evening after dinner. Testing at other times can produce unreliable results due to natural biomarker variations that happen throughout the day. The most important thing is to test at consistently similar times.

Will I have to clean the test stick reader?

No – no urine ever enters the test stick reader – it is trapped on the chip inside the test stick by a special membrane. The test stick reader is also waterproof.

Can multiple people use the same device?

Yes – the Body Coach is designed to avoid any urine entering the test stick reader, and so can be safely used by multiple people.



What platforms will the app support?

We expect to release mobile apps for both iOS and Android.

When can I download the app?

The full mobile app will be available to download in early 2020, and a beta version will be available to selected beta testers in late 2019.

What devices can be integrated with it?

We expect to offer integrations for the Oura Ring and Withings Body+ scale at a minimum.

Can data be shared to Apple Health?


Can data be shared with other people?

Yes, but please note that the Body Coach is not a medical device and is not intended to treat, diagnose or monitor any condition. You should not use or rely on the Body Coach to manage any chronic conditions.



How often will I have to charge the Body Coach?

If testing once a day the Body Coach has a lifetime of c. 3 months. If testing less frequently it will last longer.

Will I have to switch the device on / off?

No – the device wakes up automatically when a test stick is inserted, and goes into sleep mode once the test procedure is complete.

What kind of battery will it use?

We are currently exploring different options, and will provide an update later this year .

How will the device connect to my phone?

The device will connect to your phone via BLE (Bluetooth Low Energy).

How will the device recognize users?

The device will recognize the user based on proximity.



How sensitive is the Body Coach?

The device is highly sensitive – as much as a urine test strip analyzer you’d find in your doctor’s office. The device is sensitive because it uses a technology called microfluidics. Microfluidics enable chemical reactions to be performed automatically and easily using tiny amounts of sample and chemical reagents. This technology is also the reason why you don’t need to pee into a cup when performing tests.

Why is it better than a urine test strip?

Conventional urine test strips are designed to detect certain substances which may mean you need to see your doctor (e.g. glucose is a sign of diabetes). However, they can only test a small range of biomarkers, half of which do not work if your Vitamin C intake is high, and have a low sensitivity. Body Coach is able to test a wide range of biomarkers, none of which are affected by Vitamin C intake, and is highly sensitive.

Why test urine ketones? Isn't that inaccurate?

Conventional urine test strips are inaccurate because (i) they only test AcAc (acetoacetate), a ketone which is excreted less in prolonged ketosis; and (ii) they can only detect concentrations as low as 0.5mmol/L. Bisu Body Coach is the first device to detect both BHB and AcAc in urine at a sensitivity of 0.1mmol/L each. 

Aren't fewer ketones excreted once fat adapted?

No – the body excretes less AcAc, but more BHB. Conventional urine test strips make it look as if fewer ketones are being excreted because they only detect AcAc. Bisu Body Coach detects both BHB and AcAc at high sensitivity, which lets you track ketosis earlier and for longer. See our Science page for details.

Why test pH? Isn't the alkaline diet debunked?

It is not possible to change your body’s internal pH significantly through your diet – this is tightly controlled. However, your body must remove any excess acidity from your diet to maintain the correct pH. If the diet is too acidic, it places a metabolic stress on the body which promotes insulin resistance and reduces muscle retention, bone density and kidney function. There is also evidence to show that dietary acid makes it harder for the body to remove lactic acid from the muscles, and therefor reduces anaerobic exercise performance. Foods such as meat, grains, salt and saturated fat produce acidity, and foods such as fruit and vegetables produce alkalinity. As such, the pH of urine provides a helpful indicator of dietary balance.

Do you plan to release other tests?

Yes – the Body Coach is capable of testing a wide range of biomarkers. Join our product mailing list from our home page here to receive updates!
