The latest version (2.5.0) was released on 2026-09-28, so the app is still being actively updated. Good to know: it needs about 94 MB of storage.

Description
KS OS APP is the supporting application of "Kieslect ks" 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.
