Went from unreliable to unusable.
GMan#2112 on 4/20/2018
Has now completely screwed over three of my workouts because it suddenly refuses to notify me to run or walk! Zen Labs FIX THIS NOW!!!!!!!!!!!! Uninstalled.
Great 2nd app in the series
Chubbyathlete on 4/18/2018
I did the C25K and was given the option to roll right into this app and continue from where I left off instead of starting from scratch. The workouts are challenging but doable and I like how the app is a great accountability partner and tool to stay motivated.
It works
transmitsignal on 4/16/2018
Ads are not too intrusive.
10K wow

Just what I needed!
Burk232 on 4/7/2018

Awesome app
Searsro on 3/19/2018
I love how this app keeps me going. It seems like I’m Always able to push myself better when I can see how much more time I am supposed to run. It has helped me a ton on my running progress.
I like it
TFW Baby on 3/17/2018
I like the C25K app. I started with the C25K app, and when I was done I ran 5K’s for about a year. I decided to push myself, so Hy next natural thing to do was the C25K app. I finished it this week, and I’m ready for the 10K I have scheduled for next month. Will I ever do a half marathon? I don’t know.
Great running app
Anglym on 3/15/2018
This has been great to get back into running and kick it up a notch over the c25K. Love it!!
Running is the worst, right?
guy who hates running on 3/11/2018
I hate running, and I imagine if you are using this app, you are not a big fan either. But we all want to be healthier, and it would be nice to not have to deal with a gym whenever you want to exercise. It is easy to get discouraged, but the schedules and programs in the app make it easy to build up to running the 10K. You can do this!
Love it!
RitkaJobski on 3/10/2018
A truly awesome app: easy to use, helpful, and motivational. I love it, been using it for a couple of years now, and recommended it to my friends and fam.
Why won’t it stay open
Mickie_S on 3/8/2018
Trying to do the first day of the 10K app after finishing the c25k, which was great btw, but this one has crashed like 15 times already....

Amazing app
Lau_881 on 2/28/2018
Highly recommend this app. Easy for beginners
Michibell on 2/28/2018
I have used the c25k, 10K and 13.1 apps and love them all. This is my second time doing the 10K and I have noticed it runs smoother now. I love that the workouts are accessible, challenging but doable. I also love that the app tethers to my Apple Watch so I can just put my phone away and revive the prompts on my wrist and through my headphones. I recommend this to anyone who it just starting out running.
Good trainer
Paulie bbbb on 2/26/2018
Great little app. Take me a second to figure out interface, but after that super easy. Seems to be on a good schedule for training. Highly recommend
Fitness is life; use 10K to tend to living
PandaRedPanda76 on 2/25/2018
Simple & enjoyable to use. Let this be the app you need to get back into shape!
Great to get back in shape
Rick Briggs on 2/25/2018
Great way to get me back in shape. It challenges me in the beginning. I only wish they could integrate with Apple Watch.
Love this app!
Thesports007 on 2/20/2018
So easy to use and great for non-runners who are trying to be runners!!
Makes me appreciate running
Xzy 132 on 2/14/2018
I love these zen labs running apps; really encouraging and pushes me to go farther!
Helped me loose 85lb
Jake 101010010101010010001 on 2/13/2018
I started using the 5K version when I was 14, I weighed 275lb back then. In the course of 6 months I had lost 50 pounds (also with the help of watching my calories) . Then I fell off the horse because I moved. Got back on a year later after maintaining 228lb for a year. Then I got back on and lost another 38, finally getting to my current healthy (and aesthetically pleasing) weight of 190 pounds.
Love it... But!!!!
FlyTherapy on 2/13/2018
I’m loving the c210k trainer. It is definitely helping to build me up as a runner. I’m only halfway in but I feel stronger everyday. My only gripe is there’s not an Apple Watch app. This would make my life soo much better, especially as Spring approaches and I’ll be doing more outdoor activities. It would be awesome to be able to leave my phone because I have this app downloaded to my watch. There is a similar app for the Apple Watch but it does not allow for the Apple Music capabilities and what’s a run without a great playlist? Please fix this!!!!
Great app
Zing1968 on 2/7/2018
It’s helped so much getting ready for my 1st 10K.
Great App
Cute putoot on 2/6/2018
I started with the C25K and ran two different 5k’s. So now I’m training for. 10K and this is perfect for someone who’s not that experienced. Keeps me right on track!!
Da Bomb
Ghjfgkjvcchkm on 2/3/2018
Its da bomb
Can an app hold you accountable?
safean on 1/28/2018
Turns out I don’t hate running that much. 😜 I needed an accountability partner. A friend told be about the app and I’m enjoying to use it. The app is my accountability partner now. I did run a 10K last year. Rather unprepared and probably because it is a very popular run I just dived into it. My goal for this year is to beat last years time which should be easy to do, since my accountability partner is making me train for it.
Mrsali00 on 1/27/2018
Now this is coming from someone who Hated running. This app is not only user friendly but also designed for people who are learning how to run. I would highly recommend this to anyone who wants to take their fitness to the next level.
Good app
Megrcam51 on 1/23/2018
Great tool to help train for a 10k
Simple and effective!
Runnermomemc on 1/15/2018
Great app, easy to use, and beginner friendly!
Solid app
Gobigorange27 on 1/15/2018
Very solid app. Easy to use and keep you accountable.
So Messed up on 1/12/2018
I have tried a number of the c25k apps and this brand worked the best, so much so that I got this one the couch to 10K. Works absolutely as it should.
Great, easy to use, helpful app!
JanaBurt on 1/9/2018
Everything I wanted and super user friendly! Encouraging and makes me want to keep up with the workouts. Only complaint is the drain on my battery, and when a battery warning pops up it pauses the app without telling me.
Best run trainer app
faiths14 on 1/8/2018
Played around with other apps but this is best one and it’s free
KpJenna on 1/6/2018
Really motivating and great for beginners to running. This app helped me before pregnancy, and I turned right to it after.
busted ear drums on 1/4/2018
Nothing makes you run faster than having your ear buds in on a very low volume setting to have a huge GONG sound blare in your ear. Geez! Fix this!
Great App
Gimpyeric on 1/3/2018
Great app and really easy to use.
A big fan.
caringiscoool on 12/27/2017
I have never been a runner, and have always felt like it was too hard for me, and probably too late for me to ever learn. But this app has really helped me overcome that internal conversation and just go for it. I’ve never actually finished the program, because I basically just use it to kickstart me when I need to start exercising again, so I start again from wherever I feel like I need and then baby step forward. I try to run every 2 days, and just proceed according to the app. Sometimes, if a week’s run was extra hard for me and I don’t feel like I’m ready to level up, I’ll repeat a run until I feel like I’ve nailed it. It’s really chill. Integrates fine with Audible, iTunes, and Spotify. My only complaint is that if you have an Apple Watch and unlock your watch then all audio prompts stop and it only notifies you to run and stop via vibration from your watch, which is not always helpful when you’re in a world of pain running haze. A gentle buzz at your wrist is much harder to register than a voice in your head telling you you can finally stop. That’s my only complaint, though. I genuinely love this app and have recommended it to many people. It has helped me become, if not a Runner, definitely a runner, which is something I truly never would’ve believed possible.
Perfect for new runners
adamzeiff27 on 12/26/2017
Used the 5k app but then moved on to 10k because I’m running one on January 6. This app helps me incrementally get myself there day by day. Thank you!
The timers are off.
Chucho320 on 12/20/2017
Years ago, when this app came out, I could hit start on this app at the same time I hit start on my treadmill and the timers lined up perfectly. Now, a few “improvements” and updates later (you can now buy a lot more options/add-ons/features), and the timers don’t align. The app always ends up many seconds behind my treadmill. I used to wear my phone in an armband so I couldn’t check why the timers fell behind. I upgraded my phone, and it no longer fits in my armband, so I had to put it on stand beside my treadmill. Doing this, I was able to watch the app and figure out the issue. The timers end on :00 and switch over and start at :00, giving you an extra second per interval. If they fix this and stop asking for money and ratings, this could be a fantastic app again.
CheriMo on 12/14/2017
I always give a 1 star review to apps that pester me to review them. It should be my choice whether to leave a review or not. You shouldn't attempt to force me to give you a good rating.
Not bad at all
Leyna-Lu on 12/4/2017
This app tells you what to do on a run without being strict, it simply gives the notification to “run” or “walk.”
i like it
Azooz blablabla on 11/30/2017
this is an amazing app !!
A good start
Nice Tri on 11/27/2017
As a health and fitness professional, I will encourage my patients to use whatever tools work for them. This one is popular and I’m giving it a go myself. My first impression is that it is good for accountability. A long second to an actual running partner, this app still may help us to get out the door. The progression is simple, yet walking alone should be the first step from the couch for 1-6 weeks, depending on one’s fitness. What is lacking for me is that other side of running- the sprints, tempo runs, fartleks, hill work, etc. Some may argue that C210K is powerful in its simplicity. I just see it as lacking. If running a 10K truly is your end goal, fine. But if you want to improve your fitness and longevity, I recommend adding core exercises, carries, toe and heal walks, and much more that could easily be integrated into the app.
