Currently a long term Garmin user who has dabbled in Samsung watches in the past.My interest here was driven by a few things…- Bright, clear display- Styling- Weight (its crazy light)- Advanced running metrics (which im used to getting and dont want to lose)- Battery life (a huge selling point)- Price (amazing, given the features)For info – Im using in conjunction with a Samsung Fold 7.The watch is well packed/presented and super light when you take it out. The green is especially nice, and the nylon band (which i have in my Garmin Epix also) is super comfortable.Downloading the app is easy via the Samsung app store (which gets around the fact its not on Google play), and setting up is extremely easy.I used it for a run and and kept my garmin on the other wist. HR, distance, pretty much everything was identical for the full 6km I ran which was impressive. I checked every half km.It’s size is ideal and th functionality, info, data it offers is ideal for runners. Other widgets and access to apps is great on the watch, and the dial is excellent and convenient. The ecg readings are quick to do and appear to be accurate (but remember, its a watch.. not a medical device, as it reminds you frequently during the set up process).In the end I returned it, and frustratingly it was not the fault of the watch…The app. Deary me…. its rammed full of adverts for products, or points rewards, or for other features. The post run reports are good and all the data is there, but the app just overwhelms you when you interact with it and the notifications are OTT.Another personal niggle is that im used to having a ‘body battery’ metric and I find it accurate and useful. Hauwei doesn’t have this, and I believe only Samsung does it. In the end I returned it.So, the watch is superb – amazing hardware. For Hauwei phone owners id recommend this massively, and for others who can get past the experience on the app. Unfortunately I couldn’t, although im sure I could have in time, and decided to send it back.

Very light, good looking smart watch. Displays most of the relevant health related and other features for day to day usage. Compared to other device with similar features, pretty good for value and pretty good quality. has good functionality, easy to set up and connect with IOS and android based mobile phones.

I bought this watch a few weeks ago and its fantastic.. it does everything i need and more.. from measuring my exercise and health metrics to ECG, SPo2 (blood oxygen) and even has a relaxation breathing mode.. plus comparing it to my HR chest strap, the 4 pro reads really accurate HR and steps … and unlike Pixel watch 3 and Fitbit.. The Fit 4 Pro actually Syncs instantly on BT connection, without the incessant errors .. Yay..After using about 6 different trackers and smart watches over this last year, Huawei Health app is great and packed full of detailed health and fitness info, and the app is not the ” data tracking hoarder” google and the conspiracy lot make it out to be .. believe me, Samsung Health, Garmin Connect & Fitbit are far far worse for data monitoring..Just download health app from Huawei UK, install it manually, create or login to your Huawei acc, set it up with your watch and off you go..After initial setup, i went back and turned OFF “contacts”, “call logs” and “location” in Permissions on my pixel phone .. and that was it.. but when i was using Samsung Health or Garmin Connect apps and watches .. they hassled me constantly to “allow calendar, allow contacts or allow call logs permissions” access.The Huawei Health app doesn’t ask you again once you go back and turn these Permissions off in phone settings…The Fit 4 Pro is easily THE best health and fitness watch and tracker ive ever owned .. period.. so dont worry about the app, being non google, its a great watch and well worth it..

Good basic watch. It’s a shame that it doesn’t work as smoothly with iPhones as it does with android.But other than that it does what it does really well.Step counter, heart rate monitor, ecg, sleep tracking, breathing, stress monitor, Bluetooth phone connection tor receive calls and messages, set alarm, timers etc. crisp display quality, fits very comfortable with interchangeable straps with a click. Price should be lower than £200 though for sure.And most importantly…2 weeks of battery life!Overall, it’s a good product.
