Azoi Kito+ Review

What we think

The Azoi Kito+ is a very small, light, health tracker, perfect for carrying around on the go, especially for iPhone users as it fits seamlessly into the back of a case. However, its price feels rather high for what it does, and we feel its app could be improved more.

Measuring just 97mm x 53mm x 3.4mm, and weighing 22g, it is definitely a minimalist piece of kit. Being small and light makes the Kito+ a very convenient size, so you will easily be able to keep it with you on the go, allowing you to measure your vitals whenever you want.

It operates as a standalone device, in tandem with the app on your phone. For those with an iPhone 6/6 Plus or iPhone 6s/6s Plus, the product comes with two cases included for you to put your iPhone into, with the Kito+ being placed into the gap at the back. Other phone users will need to hold the Kito on its own to measure their vitals.

The two largest sensors are the two silver ECG Electrodes, which you place your index fingers onto. You then place your left middle finger on the tiny silver temperature sensor, and your right middle finger on the SpO2 sensor, which measures your blood oxygen levels.

The power button is located in one of the corners, fitting flush with the unit. Beside that is a tiny LED light which comes on when the device is turned on. When you load the app, you are asked to turn on Bluetooth, and then you need to press the power button on the Kito+ so you are able to start the ‘check-up’.

Features and function

The Kito+ measures your ECG (measuring the electrical activity of your heart), heart rate, skin temperature, respiration rate, and blood oxygen levels, all at the same time, and in just 30 seconds, which is very convenient.

While the measurements are being taken, you can see the ECG displayed on your phone, as well as the other vital readings. Once the recordings are complete, then you can view all of your statistics on one final screen, and save these readings to your personal history log. These can be viewed again later on, and even compared to other days’ results. You can also share the results with your family, friends, or doctors, if you so wish.

This is one of the main pros for the Kito+, as it can lead to good communication with regards to your results, and it is very easy to share your results using the app.

When using the Kito+, I found the heart rate, ECG, respiration rate and skin temperature monitoring all worked well, appearing to be accurate and rarely not being measured. You are meant to stay still while the measurements are being taken, but I tried suddenly moving around loads during one test to see if the Kito+ responded accurately. I was pleased to find that it did, with my heart rate rising up accordingly, indicating to me that the measurements it takes are accurate.

However, I did have issues getting the blood oxygen levels recorded properly. When the recordings had finished and the results page showed up, it would show an icon indicating that the blood oxygen levels had not been measured, with no accurate explanation each time as to why this had happened, just a list of general possibilities for it failing.

After a lot of experimenting, I figured that the blood oxygen sensor was more likely to give a reading when I put the very tip of my finger on the sensor, and held it there more gently than the other three fingers on their respective sensors. The ECG measure needed quite a firm pressure, while the blood oxygen metre needed only a light touch.

This was the main issue with the product, and otherwise, it is a delight to use. It’s incredibly simple, you literally just place four fingers in the correct positions for 30 seconds, and voila.

The app

In order to use the Kito+ you must have the free app downloaded onto your phone. It is compatible with Apple devices, and Android 4.3 and above phones.

The Kito+ app, which is free on both the Google Play Store and Apple App Store, syncs your phone to the device. You are asked to enter some personal information at the start as you create an account, which can be secured with a password to prevent others accessing your personal information.

I felt like there was a lack of instructions with the Kito+ overall, and it took me a bit of time to get used to the app and the different features within it. Therefore, this is an area of concern especially if it is aimed at older people, who are typically not as up-to-date with technology as younger generations.

I wanted to view a decent number of graphs quickly and easily from the home screen, but it took a while to find them, and I felt like the graphs could be more user-friendly. This would be another area for improvement for Azoi.

The app allows for more than one account on the app, or even record the vitals of a guest, which is good, as it means the whole family can store their health information if they wish. You can also schedule reminders to prevent you forgetting to take a reading, change settings and even sync it to your Fitbit, if you have one.


If the white LED light on the Kito+ blinks, it means the battery is low and needs charging. To charge it, plug in the supplied USB cable to a power supply, and connect it to the small Kito+ charger, also supplied in the box.

This small charger snaps into place on the Kito+ through the use of magnets, and if you switch the device on, you will see a blue light to indicate the device is charging. Once the device is fully charges, the blue light will turn white, and you are ready to use the Kito+.

The battery life of the Kito+ is supposedly around two months, which is very good even if it is a very small, basic device.


This is the main drawback in my opinion, and the main obstacle that could prevent the Kito+ from being more popular. While it performs fairly well overall, and can be definitely be a useful piece of kit, it doesn’t have much to it in my opinion that warrants paying £100.

A price of around £50 seems more reasonable, I think, as I can definitely see it being of benefit to many people, just not at too high a price.


While fitness trackers are very common nowadays, health trackers are not. Heart rate monitors may be built in to a number of fitness trackers, but they do not record other information about your vitals in the way the Kito+ can, and it is great that you can measure your vitals and get the information instantly.

I think the app could be improved if you could easily see each of your measurements on a graph on the homepage. I also think the price could be reduced by quite a bit, as I do not expect many people to be willing to spend £99 on it, and it was annoying how frequently the blood oxygen levels were not recorded properly.

While we don’t expect this to be a mainstream product, there is definitely a market for the Kito+ with doctors and other healthcare professionals being able to view your stats, as well as yourself, obviously. If frequent measurements of your vitals is important to you, then you should definitely give the Kito+ some serious consideration.

However, as Azoi point out, the Kito+ should not be seen as a diagnostic tool, so be sure to always check any concerns with your doctor rather than relying on this.
