It's always worked great for me I haven't had any problems with this app - it's much more accurate than some of the others (looking at you Runtastic), hasn't crashed, and provides the information I need.
Problems lately with stopping activities I enjoyed this app for many months, but lately it's not usable Any more. For my new phone I unable to stop an activity from recording, so this app became useless for me. I have the Samsung galaxy s4 mini.
Overclocks in difficult environment Walking along the river the error was only +2% and perhaps my standard was off by that much. Walking 2.1 miles down the west sidewalk of Broadway it said 3.18 miles and showed my track as frequently crossing to the other side or entering far into buildings. It needs to detect multipath and other poor signals and smooth more aggressively when they happen. Oh, and beforehand I set the coarseness to 30 feet. Probably worse at the default 10 feet.
Counts calories Fun to use. Works well. Have only used it for walks on streets so far. One complaint, large program and doesn't allow installation onto SD card. Almost had to uninstall it because I ran out of memory. Get it to install on SD card and 5 stars. I want to keep using it but might still need to uninstall due to memory issues. I want to purchase but only f I can put on the SD card as I still am low on memory.
Super powerful free version It's amazing how much this app does for free. It's super easy to use, can go from being turned on to tracking me within seconds. It even works in airplane mode so long as the GPS is running. My cheapo phone is good for hours & hours with only the data turned off. I can't say enough good about this app.
HTC one x This app is really good, it is so accurate and has helped me to learn new mountain bike trails and also find my way back out of some. The amount of useful data this app provides is extensive. It will track every little twist and turn you do and maps it out on a proper map of your location. Using mostly GPS and pretty much NO mob data and battery. Thank you very much for such a brilliant app.
