Half Marathon Trainer: 21K Run

The simplicity of this app and the fact that it's time based rather than mileage based makes it head and shoulders above most of them - and I've tried them all. The mileage tracking is a little off and always seems to underestimate so I use Strava at the same time for that. Overall though, I love it. The training plan feels "bite sized" and achievable so it almost tricks you into running the mileage. Perfect for beginning runners or first time distance trainers.

I like the app as far as getting me ready for my half marathon. I am 2 weeks away from my race and I am already running the distance. I have never ran 12 miles before. The app did great in preparing me. I have 2 suggestions... I have been frustrated several times during my runs because of the forward and back buttons on the screen. I like to carry my phone as I run so I can easily see my progress. If you accidentally touch the forward or back button it will start you over or send you to the next stage of your work out! No way to go back to where you are in your run! Please either do away with those buttons, make it a two step process... "are you sure you want to start over" or have an option to go back to where you were in your run. If I am 9o minutes into a 120 minute run and my finger or once even my clothes hits the back button, your screwed unless you know the exact time you started the run after your warm up. Secondly, I wish there was a feature to keep up with distance. I have to run a second app on my phone to keep up with how far I am going and my time per mile. Would be nice to have that feature built in.

I just typed a super long and detailed review of this app which was lost. Ironically, this is similar to the 43 minutes of my life that were lost after I spent them running in the blistering heat only to have this app skip back to the warm up after 48 minutes when I accidentally grazed the button with my finger. I understand that you can lock your phone to "prevent" this, but that's rather impossible when I'm forced to use other running apps simultaneously because this one doesn't show your pace when you run! There are free apps out there that are MUCH better for runners. Why is it Sooooooo easy to just delete an entire segment from a run?? Shouldn't there at least be some kind of confirmation prompt before just skipping back and deleting all traces of hard work/torture?! Why can't the app record all of the runs that we do and just ADD the extra time if the runner chooses to go back to the previous segment?! Or why can't the user manually go back and edit the run after it is completed by deleting segments if they don't wish to have them factored in?! This is beyond annoying. Otherwise this app has good potential.

Overall I’m satisfied with this app. When running outside it gives a good enough estimate of distance. I like that it’s time-based, not distance based training. Haven’t had any issues with it not notifying me of alerts. It does have one major flaw though. To scroll through the different workouts you have to drag the bar on the bottom of the screen. This bar also has a check box that gets filled when you complete a workout. It is very easy to accidentally check or uncheck these boxes and permanently delete a workout. There is no equivalent manual entry - the one that exists doesn’t allow you to put distance, map, or calories burned - and no recovering the lost information. For this reason I’ve given the app 3 stars. There is also no way to view upcoming workouts other than scrolling through day by day which increases the risk of accidentally deleting one if you (like me) like to plan ahead. A calendar view would help this issue, and a “double check” feature would help the other one and if the app includes these changes in a future update it will be 5 stars for me for sure.

I've been training for a half marathon for awhile and used the app quite a few times. Probably the best feature to me is that it is a program already built in that is very easy to follow along. Bad part? Here in the winter I've been running indoors on a track and it couldn't be any worse as far as accuracy on distance and times sadly. I run with a fitbit as well so I know how many miles I've actually ran, also can tell obviously by how many laps I've ran, but it would be great to be able to count on just one app for all of my running needs. When I say inaccurate I mean, I actually ran 5 miles but it's saying I've run 3 in the app, maybe it is just a poor connection and it cannot register the GPS signal? But I've tried multiple indoor tracks and all have had the same problem. Now, that said, when the spring comes around and I'm running outside, I'm sure it will be better.
