APEX is equipped with machine learning capability. The more you run outdoor with GPS on, the better the readings will be generated in the indoor run / treadmill mode. If you have limited or no outdoor run history with APEX watch, more than likely you won’t get a satisfactory result for indoor run. During outdoor run, APEX learns your running habits and gathers related information like GPS, cadence, gesture, pace, heart rate, and more to build up and improve an individual running model. Whenever you are running with limited or no GPS signals, motion sensors and the running model will kick in to provide best possible running metrics.

UltraMax mode is a setting for GPS on APEX. When selected, the battery life using GPS can be extended up to 100 hours on APEX 46mm and 80 hours on APEX 42mm. The reason behind this unreal battery life is because of our unique algorithms and mechanism. For every 2-minute period, the GPS data is recorded for 30 seconds. APEX relies on motion sensors, machine learning algorithms and individual running model for the remaining 90 seconds. Not only can APEX provide nearly accurate GPS tracks and running metrics compared with normal GPS modes, the battery life is also much increased to be used in the toughest conditions.

At least in the near future, the COROS app on smart phones and 3rd party platforms like Strava and TrainingPeaks are the only customer facing portals for analyzing and exporting your workout data. We work hard to provide a streamlined, user friendly, convenient yet powerful app that is beneficial to all COROS users. If you wish to view your data on PC or web, we offer the option to export your workout via up to 5 different file types by email. You can also link your COROS account with 3rd party platforms to utilize their more than adequate functions. We try our best to display raw data on these platforms for your complete training analysis.

No, there’s no option to turn off any sensors (other than GPS), Bluetooth or the screen. We have conducted many tests to come up with a solution that meets our battery life requirement and provides a user friendly experience. We use always-on memory LCD screen for APEX to provide great visibility under direct sunlight. When the backlight is not activated, the screen has ultra-low power consumption. When not in any workout mode, many sensors and Bluetooth may enter into a less active status. Please rest assured and enjoy the ultimate experience that APEX brings to you.

We work hard to streamline the operation and learning process for APEX users. With new features and improvements being added monthly via firmware updates, it is challenging for us to provide a detailed and up-to-date user manual. For the most updated product specs and firmware release info, please check the SPECS sheet on APEX’s product page and Release Notes page. Every setting and option should be straightforward on the watch and the COROS app. We apologize if you are struggling with using or setting up your APEX.

We are working actively on improving the APEX watch. Our development team is fully dedicated and the most diligent team out there. However, our development focus is largely restricted to the most critical aspects of APEX due to factors like team size, resources, priorities, schedules, unexpected bugs, and many more. We appreciate all the feedback we have received and agree with many of you on the product features and experience. However, one of our main and ongoing priorities is always the improvements to our algorithms for accurate workout data. As a result, many great changes and additions to APEX can’t be realized in a timely manner. We apologize if your current experience has been affected by the lack of desired features and improvements. We promise you that we are willing to listen to every feedback and will try to make these great suggestions available as soon as possible depending on our schedule.
