About this app

Kstyle OS APP is the supporting application of "Kieslect" smartwatch, with the following functions:
1.One of the main functions of the APP is to push the incoming calls and SMS/MMS messages received by the mobile phone to the associated smart watch, so that you can answer and view the SMS/MMS on the watch side; when the watch side rejects the call, you can quickly reply, and the APP will send a pre-configured SMS to the caller at this time. It should be noted that the APP will request "SMS and Call Log Permissions" to implement these functions, without these permissions the application will not be able to use.
2.Record the heart rate data collected by the smart watch, and display it in the form of a line graph and a histogram according to the heart rate data;
3.Record the sports data collected by the smart watch, including the number of steps, stride frequency and distance, and display them in the form of line graphs and histograms;
4.Set reminders and alarms for your smart watch.
5.Not for medical use, for general fitness/health use only

"I like the smartwatch( Kieslect Elfin) overall, but I was disappointed with the limited number of watch faces. It would be great if the company added more options so users can personalize the watch better. The current selection feels too small compared to other smartwatches.""I like the smartwatch overall, but I was disappointed with the limited number of watch faces.

I'm having a problem with the app. It can't find my city, so the watch is taking the wrong location coordinates and isn't picking up a signal GPS, please solve the problem. im in Marsa Matrouh Egypt The app shows me as 136 kilometers away from my actual location.

After the last watch update, Night sleep function is disabled. I tried everything (restart, factory reset, time edit, full charge...) and no result. It always says "no night sleep ..."
