Hiking Trail HK 4+

1.Export gpx function so users can use other sports app .such as strava.
2.Parallel download all google photos in home-wifi for offline-use in a user-specified trail in case get lost or confirm famous tourist spots with poor internet connection outdoor.
3.Compatible with iwatch and show photos and user-planned and user-specific temporary direction on the trail.

1. For GPX export, please check:

2. Do you mean the photos shown inside our app? Our photos come from Flickr, not from Google. For Google Photos, maybe, you can use Google's app. For Flickr's photos, normally batch download may violate their terms of service. The latest version supports showing cached photos during offline. Photos may be cached for a few hours, and you may load the needed photos beforehand.

3. As the map rendering engine we are using does not support watchOS yet, so we do not support Apple's watches yet. But we have a Wear OS version, and it works with iPhone too. You may want to try it:

1)Elevation Gain/ Loss is totally off , differences can be 70% to almost double 2)there were many times a grey line appeared behind the red elevation profile line, and that’s when most the elevation track difference occurs . how did that happen? Is that bug? Tried reinstalling but didn’t work. Besides the elevation issue , this is by far one of the best trail tracker apps . Thank you

Hi, the computed (red) elevation gain/loss is based on low resolution elevation data which only contains elevation values for some sample location points. The elevations for most points are just computed from those sample points. The logged (grey) elevation gain/loss is based on the elevations of the logged location points. The logged values are calculated based on the GPS satellite signal received by the phone, which in turn is affected by various environmental factors. The app just calculates the elevation gain/loss based on the raw logged data. If the result is not satisfying, you may try to export the track as GPX, and use some other tools to simplify/smooth/clean up the track to see whether the result is better.

Extremely accurate trail maps and easy to use route planner tools. Be careful as this app is extremely power heavy and will obliterate your battery. Plan your route at home while plugged in, then use it for quick checks along the way.

Thank you for reporting the battery issue. We will try to find some tools to analyze the battery performance. But if the problem is very extreme, it may be due to old phone model or aging battery. As real-time map rendering, GPS, and track logging are power consuming by nature, using the app could be comparable to playing a game, and there may not be much room to improve.
