### 5/5 — Good, just wish it had a light

*2026-05-23, version 3.2.10*

I've been using the Smart asthma device and app for a couple of weeks now. I had no problems at all connecting the Bluetooth convertor with my phone and it's been reliably picking it up every time I use it.

It's a significant improvement from manually recording my readings in a spreadsheet and the ability to download my data is great.

The device itself is fine, the mouthpiece is very big and took a while to get used to.

Technique is everything. I've found I always have to use my iPhone torch to take the reading, conviniently, the app will turn this on and off for you automatically which does help. If I get the technique right, it registers every blow first time but it took me some practice to get to this point and I have to put my hand and devices in a very specific position for this to work.

The device seems more accurate than my old mechanical peak flow meter.

Overall I'm very happy.

Suggestions for improvement :
- the biggest one is a light built in so I don't have to balance my phone on the device awkwardly every time. This would make a huge difference!

- I would like the option to record different types of symptoms, breathlessness when talking / chest pain / fatigue so I can better see what's happening for me. It doesn't necessarily need to appear on the main chart though.

- i'd also like somewhere to record steroid tablet courses so I can keep track of how frequently I'm having to have them and how quickly I recover after them.

### 1/5 — Terrible

*2025-08-31, version 3.2.9*

This unit fails to read with enough light.  Impossible to use with severe Asthma.   Easily do best of three with a traditional plastic peek glow and write down the levels.  With this unit it’s turned off 5 times, recorded one reading failed on 7 goes. This is make my breathing WORSE.  Needs reporting.  Not fit for purpose

### 4/5 — Good Product

*2025-06-05, version 3.2.8*

It’s a good app and product with a lot of potential. But can be a bit temperamental. 
There are a couple of bugs that really need fixing. Overall good!

### 1/5 — Can’t start an account with app

*2025-04-24, version 3.2.6*

I tried setting up my account and it says it sent a verification email but the email never arrives. If you try to set up the account again, it says this email is already in use. I tried a different email but the verification email didn’t come for that either.Hoping i can change my review once I get some help .

### 1/5 — Невозможно зарегистрироваться

*2024-10-10, version 3.1.6*

Невозможно зарегистрироваться.  Постоянно не проходит пароль по требованиям.  И не приходит подтверждение на почту.

### 4/5 — Update for USB-C needed

*2024-07-06, version 3.1.2*

After switching to a USB-C port iPhone, the application stopped seeing the device. Everything used to work properly when lightning adapter was used for the previous iPhone.

### 1/5 — App startet nicht iOS 17.4.1

*2024-04-04, version 3.1.0*

Beim Login stürzt die App direkt ab -> gelöscht

### 5/5 — Great device

*2024-02-12, version 3.1.0*

I bought this device as my nhs peak flow meter was awful and I knew the readings weren’t accurate by any means and it looked like it might be worth a go.
Firstly - the Bluetooth bit I really struggled to use as I also have other devices Bluetoothed to my phone - watch, hearing aids and they needed to be disconnected before I could use it. 
Once I got a headphone jack for my iPhone 15, this was a game changer, just a quick switch off Bluetooth for the puffs and away you go.
It’s simple and easy to use, and it links with Apple Health as well, so all my asthma info in one place. 
I would highly recommend it, indeed I’m going to try the rescue adapter now as I have no idea how much is left in mine.

### 5/5 — Brilliant

*2024-02-12, version 3.1.0*

Having recently been diagnosed with asthma this device helps me track my peak flow and helps me understand my asthma
