So, first and foremost if you do not use a Hauwei phone you have a host of issues. You need to download the health app via an apk and provide lots of permissions. I couldn't get this to work correctly. The watch is really a fitness tracker that accompanies your phone. You can't really reply to messages apart from quick replies Celia doesn't work unless you've a Hauwei phone there is no NFC so no payments and no WiFi on this model. So that's the negatives. The positives, if you're seriously into running this watch is for you lots of tracking with AI assistance to improve your performances. 100s of exercise options and the battery life is amazing. I should also point out that there limited third party apps you can download, so no Google, Spotify or Strava and therfore syncing data is limited. I returned the watch as it just didn't do all that I hoped. The watch runs Harmony 0S due to Huawei no longer having access to Google and whilst Harmony OS works it lags behind Wear OS or Tizen. In my opinion Hauwei will get to where it needs in time but if you are looking for a more integrated smart watch and using Android I would suggest looking at the Ticwatch Pro 3 or Ultra or the Samsung Galaxy Watch 4. Both watches will provide all that the tracking you require (with their own quirks) but will be easier to use as running Wear OS and therefore being not just a fitness tracker but a proper smart watch. However, if you do not care for the smart functionality and just want a watch where it sits along side your phone with incredible battery life and a fantastic screen then the GT3 could be for you. If you definitely wish to sit in the world of Hauwei and want to perhaps future proof for updates I think the GT3 pro is being released which will have NFC and WiFi- but whether you can make payments from your wrist is yet to be determined. That's about it but hey, it's your hard earned cash so you do you and enjoy which ever device your purchase.
