Customer Reviews

Amazing app!

First and foremost: I am not one for exercising. Never have been. But after year after year of diets that never got me less than 10 pounds lost, I thought I'd get into running, but I didn't know how to even begin. Someone suggested this app, and it was the best suggestion I've ever gotten. I love how it tells you when to start running and walking. It really helps you want to improve. Which is why I gave it 4 stars!
Now with that being said, being in a networking and sharing world, the sharing function doesn't work right. I want to share the picture when I finish, but it only does it half the time. I have it synced with my Instagram, but it never uploads to it. It'll share a status on my Facebook and when I go back to share it on Instagram, the option to share my progress is gone. If this gets fixed, I will up the rating to five stars!!

I am not a runner…

I've been losing weight for the past 2 years and occasionally, I hit a plateau that's hard to break through. Friend after friend suggested that I get into running. And friend after friend suggested C25K as the easiest way to get into it. So I got the free version and immediately let it sit there for about 6 months.

I'm 5 weeks in (Oct '14) and not only do I like the program, I have signed up for my first half-marathon.

The app is really just a preset interval timer with voice prompts. But that's all it needs to be, I guess.

There's are some nuances that are annoying but are probably more to do with iOS than the app. Like your mute button cannot be on or you won't get prompts. Also, in my experience, if you start the app before the podcast app, you lose the prompts. But if you start the podcast app and then C25K, you get the voiceover. Maybe that has changed in any of the minor updates in app or iOS but I have my routine of running the apps to get them all doing what they are to do.

I do wish that either the app did more or it was available as a purchased training module for any one of the other GPS exercise tracking apps. Having to have 2 apps to train/track is a bit annoying. But if you just want to train to run, this one is a really solid way to do that.

Just A Few Things I Don't Like

OK I like this App and it did get me to a 5k BUT
The pop up advertisements are very annoying. I wish they would cut these back some or just make me pay a few bucks for the app instead. I would've paid for it to have no annoying advertisements.
Also- If you don't have the app pulled up it won't tell you what to do. So if you are running and pull up pandora to change the song it won't say "start walking" until you go back to the app. I wish it would still talk as long as the app is open.
Like other reviewers have said, it's a little dated looking and needs some updates.
Other than that- I'm very happy with the concept and it really helped me reach my goal.
