Trek M
Read full descriptionHide full description
Trek M is a travel data display, logger and navigator for trekkers and travelers. It displays basic and enhanced GPS data and optionally logs it and shows condensed navigation instructions on your ActiveLook smart glasses’ heads-up display and also on iPhones and iPads with built-in cellular support. The information is in your preferred units for speed, course and altitude. Additionally, the app collects and calculates derivate information such as distance travelled, maximum and average speeds, highest and lowest altitudes and ascent and descent. The collected data is visible in real time in the watch (GPS data only) and smart glasses, iPhones and iPads (both GPS data and navigation directions). The location data can be saved to a GPX trace: you can follow your current position, active trace or stored traces on the map. The watch app can be also used to remotely connect the phone: start or stop the trace, reset or pause both devices. Trek M builds on and replaces the GPS M app, which is no longer updated but still available for the time being. Images 1: Start screen with speed, distance travelled, current course and altitude, additionally duration from start, maximum and average speeds, maximum and minimum altitudes, cumulative ascent and descent. 2: Tap on map (requires iOS 17.0 or later) or enter street address or contact name for destination 3: Navigation screen on iPhone. Smart glasses show direction arrow, distance to next step, distance travelled and current speed (Image is from simulator: simulated route does *not* lead to given destination, thus directions indicate navigation error and suggest corrective turn). Please see the User's Guide for print screens from actual device, route and navigation. ** Note ** - The navigation instructions are based on Apple Maps. The supported languages are English and Finnish. Any other Apple Maps supported language can be added, or the phone can temporarily use English as the primary language. - iWatches are not supported with iPads - Navigation is only supported with iPads with built-in cellular support Please check out the User's Guide at https://pbase.com/pekkal/trekm before purchasing the app! Trek M uses ActiveLook SDK, published under the Apache 2.0 license (https://github.com/ActiveLook/ios-sdk/blob/main/LICENSE)
