MACSOLU  This developer has got to be setting a record for amount and frequency of updates.

SUF  Absolutely fantastic piece of software. The Garmin Software that comes with forerunner watches pales in comparison. This is easy to use and gives great insight to workouts.

As an aside, there seems to be a few little bugs to work out but the developer seems to be working non-stop as of late. Keep it up lad, your efforts are appreciated.

KAYEL  This app works great with the iPhone and iTrail. I am still discovering features and I find it very useful to track my workouts and map my progress in training off-road. In addition, the developer is very responsive and helpful. Definitely worth a try. Thumbs up.

JORY  I like this app a lot. I've been using it daily since I bought my Garmin Edge 705 and really like nearly everything about it.

The only thing I don't like is that the developer calls it "freeware" when it's really "nagware". The app is "free", but nags you to send a "donation" every time you launch it, requiring you to check a box in order to click the dismiss button. Each day you don't "donate", the time you must watch this nag increases by a second or two.

Honestly, I'd have bought this app three months ago if the developer was honest about it being nagware or shareware and seeking registrations, not "donations".

MSJSTW  Love this app!!

Quick question: Does it support the new iPod nano (5G) yet? I seem to have some problems there - TrailRunner seems unable to import the workout.

But it does work if I choose the nike+ website option.

Thanks alot!

UPALMACDATE  I like this piece of software, it works well and my results can be modified and exported easily. I wish there was a player like Garmin Connect, but otherwise most excellent.

TIJNTIJN  This programm is very helpful in planning and measuring the distance of new trails around the place I live. Also the import of gpx files and the info from my Garmin Forerunner is working like a breeze. Besides that, the developer is really working hard improving TrailRunner time after time, making it so worth to me to pay the support fee.

HEAVY_SHOWER  Sorry about the delay -- just a note to say that TrailRunner, actually, since several updates back, has stopped causing all that havoc to my preference files -- all original .plist extensions remain as is. Thanks.

On another note, TrailRunner is greatly appreciated, and is a fun way to keep stats on my jogging routes.

ARS  I am only an occasional user of this software, so that I skip many of the, for me too frequent, upgrades the developer makes. This does not take away however that this is very nice piece of software.It works very welland I like the (recent?) the possibility to see your trail with Google Earth. I think the software excels at showing where you have been (after having recorded your track with a GPS). It is not always as useful to plan a new hike, as it uses free maps which often do not trails marked on them. I do not hold this against the software, as it would cost money (usually) to get such marked up maps (via Topo e.g.). Some other sites have free trails in GPX format (I believe the backpacker.com site has these),sothe user has to download them first.

JUST A USER  Many Thanks! This is just fantastic, using it together with Trails on my iPhone.
