When is Bisu Body Coach coming out?

Bisu Body Coach is expected to be in beta testing in late 2020, and to go on sale in 2021. We originally aimed to sell in 2020, but experienced significant delays due to the coronavirus.

What stage is the product at?

We have an advanced prototype which is being optimized for batch manufacturing.

How can I become a beta tester?

Join the beta wait list here to receive updates.

How much will it cost?

While we can’t give a final price right now, our aim is to have the device cost around $100, with a cost of around $20-30 per month of test stick use, depending on testing frequency and subscription length.

Where will you ship?

We aim to ship worldwide, but support will initially be in English only.


How are tests performed?

Take a test stick, pop it to the triangular position by squeezing the sides, and extend it so that the chip inside is visible. Briefly dip the absorbent pad on the end of the chip into the stream of urine while using the toilet, then close the test stick and place it on the test stick reader. The reader will automatically wake up, perform the test and send the results to your phone in 2 minutes. See here for animation of the product in action.

How often will I have to perform tests?

We generally recommend testing twice a week, but testing once a week will still provide you with actionable date.

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 – the test stick is designed so that no urine ever enters the test stick reader. The test stick reader is also waterproof.

Can multiple people use the same device?

Yes – Bisu 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 beta app will be available to beta testers in late 2020. The final mobile app will be available to download in 2021.

Can data be shared to Apple Health?

Yes. Connecting to Apple Health enables your urine data to be cross-referenced against other data such as your activity, bodyweight, sleep and blood glucose.

Can data be shared with other people?

Yes, but please note that Bisu Body Coach is not a medical device and is not intended to prevent, diagnose, monitor or treat any condition. 


How often will I have to charge Bisu Body Coach?

Approx. once every three months, assuming one user testing a few times a week.

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.

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 accurate are Bisu Body Coach's measurements?

Bisu Body Coach is approximately twice as sensitive as a clinical-grade urine test strip reader, and we expect to further improve sensitivity by the time the device goes on sale. This improvement is possible because Bisu uses a technology called microfluidics. We will release a full set of externally-validated accuracy data in 2021.

Why is it better than a urine test strip?

Urine test strips were first invented in 1956. Since that time, there has been only one significant invention – making these test strips scannable with a mobile phone. The same 10 biomarkers are still being tested. The same crude measurement method is still being used. And the same messy user experience has not changed. 

Bisu Body Coach is a next-generation urine analyzer that uses cutting-edge microfluidic technology, novel design and intelligent software. Its extending and retracting test stick lets you capture a small sample during urination, without needing to pee into a cup or hold a dripping test strip. The stick reader automates the whole measurement process, and calculates the result with superior accuracy to even clinical-grade urine test strip readers. The microfluidic chip enables new biomarkers to be tested that are not available on conventional test strips. The app software interprets the result taking into account a wide range of variables including your profile, goals, preferences and activity. 

Why test urine ketones? Isn't that inaccurate?

Conventional urine ketone test strips are inaccurate because they only test AcAc (acetoacetate), a ketone which is excreted less in prolonged ketosis. Bisu Body Coach tests both BHB (β-hydroxybutyrate) and AcAc in urine, which lets you carry on tracking ketones even after conventional urine strips stop working. The ratio between these two ketones corresponds to the depth of ketosis.

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 – this is tightly controlled. However, your body must remove any excess acidity generated by your diet and exercise to maintain the correct pH. The process of removing acidity not only places a burden on the kidneys, but also depletes precious resources – bicarbonate from the blood, potassium from muscles, and calcium from bones. 

In the short term, an acidic diet creates a sub-optimal environment both for muscle mass retention and growth, bone strength, and exercise performance. In the long term, an acidic diet accelerates the decline of kidney function.

Finally, urine pH is also a helpful indicator of dietary balance, because it reflects the ratio of intake of animal protein and grains to fruit and vegetables.

Bisu does not condone or endorse the use or sale of any product, supplement or dietary program which claims to modify the body’s internal pH.

Do you plan to release other tests?

Yes – Bisu Body Coach is capable of using a wide range of test sticks. After launching with the diet test stick, we plan to release new tests for tracking fertility, baby, pet and oral health (saliva).
