Went to Stowe this past weekend and tried out SkiTracks & AlpineReplay for the first time. Here's an objective review of both apps on my Samsung Galaxy S3. I was able to use both apps on Airplane mode with my GPS enabled.
I used SkiTracks (99¢ one time app purchase) on my first day of two. I was at the resort just under 6 hours, and was able to pause tracking during my lunch break. Battery life was at 71% when I was done with my day. While it was tracking, you were able to see time elapsed, max speed, distance, etc. Here are some screenshots of the saved data:
The only thing that looked funny here is that short dip in between 10-15miles under profile... I did not go on any mid-mountain lift. This may be a GPS signal error.
The map is really cool... This is default map + mile markeer view. Here are the options on the right hand side in this order: default map, satellite, satellite w/o labels, terrain map, display lifts/runs, display mile markers, display...? (not sure what this is), display every 15 minute marker.
This chart displays altitude and speed, I think where the flat line is on speed is when I was learning to go through moguls for the first time!
You can also view your data separate by the hour, lift/run, and every 5 miles. You can also tap into each one and get an expanded summary (like the main screen) for each entry.
With SkiTracks, you can export and share a KMZ file, for use in Google Earth and Maps.
AlpineReplay (free app and account; need to pay for premium account), I used on my 2nd day. That day was much shorter (thanks daylight savings! ;] ), but still used a bit more battery than SkiTracks... my batteries were at 68% when I finished recording on day 2. We did not stop for lunch during our ski runs, so I can't testify if there's a pause/resume function.
After I finished recording, here's the summary I get...
The view is a simple list. It does include some new info like Calories, Resting Time, Air Time and Jumps (1 jump for .9 sec!? I don't even remember it! ;] ) You can click into # of runs to see your different runs, and each one will lead to another list identical to this, with data pertaining to that particular run.
AlpineReplay does give you a web view of this data:
https://www.alpinereplay.com/stats/u?uId=230646&vId=378482 but as you can see is still much simpler than SkiTracks. AlpineReplay has a lot social aspect on their website, but it's not a selling point for me.
The cool thing about AlpineReplay is that the resort info is very well managed. It knew which mountain I was at. However, if I want the app to identity each lift name, trail name, and run angles, I will have to pay a premium subscription.
I personally prefer SkiTracks. I like that I can download a KMZ file for my own records. I was unable to find that on AlpineReplay... I also really like to be able to toggle, in SkiTracks, the same data into different views and units. It's a very powerful app. I really wish they had a web view to go with their app.
I'll definitely be using SkiTracks on my next snow day!
Until I get to Vail that is. Then I'll have to try EpicMix. ;] I'm loving their design.
