The watch supports heart rate measurement and can be used with various apps, as it is compatible with Android and supports many third-party apps. Whether the heart rate measurement can be shared directly with three specific apps at the same time is not explicitly mentioned in the official specifications. Synchronisation with apps such as Strava, Spotify and AllTrails is possible, but the simultaneous, automatic transfer of heart rate data to three apps is not clearly documented. I'm not entirely sure whether the heart rate measurement can be shared directly with three apps at the same time. The information I have does not fully answer this question. For a precise answer, I recommend taking a look at the app documentation or the Community.

As soon as we are able to obtain these from our suppliers, we will be happy to implement them in our range.

No, in this case the name of the retailer would be visible. The price comes from us. Due to different suppliers and delivery conditions, there may be price differences compared to other suppliers, especially in international comparison. We always try to set a price in line with the market, but this is not possible for all products. Here we have quite high procurement costs and therefore cannot offer a lower price.

Yes, you can store music files on the watch. The watch offers around 2 GB of storage space specifically for music, so you can play songs offline. Music files must be in MP3 or AAC format so that they can be played on the watch.

Unfortunately, we are currently unable to offer the desired version. A USB-C charging cable is included in the scope of delivery.

Unfortunately, we are unable to provide technical support for this product. I recommend that you contact the manufacturer OnePlus directly for more information on the ECG function and the error message. https://service.oneplus.com/de/contact
