Good trainer
Paulie bbbb on 2/17/2018
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
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!!

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.
I used the C25K app...
TFW Baby on 12/13/2017
I used the C25K app and loved it. Now I am training for a 10 k so I’m going to try this one out. I’ll let you know how it goes!
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.
QuestJones on 11/27/2017
Helped me prep for runs.
First run on 10K app
Blixter77 on 11/26/2017
Used C25K to work up to a 5K over the last couple months. Decided it’s time to kick it up a notch. Works identically (which is great) and it skipped several weeks that were covered in the C25K app.
Love it!!
Flnfrgge on 11/24/2017
I have done a C25K app similar to this one years ago. I stopped running after I finished it because I couldn’t didn’t know how to work into a 10K. (and lost motivation) I decided to try this as inspiration to work straight to a 10K. Loving the fact that when I complete it, I can click a link that will take me to their half marathon training app (if I decide to go there).
Great app...could use a couple more features
S43D06 on 11/24/2017
I've been using the app for a couple weeks and it's doing exactly what it's supposed to do...get me off the couch and back in the pavement! It has a lot of bells and whistles but one thing I'd like to see is a way to control the volume of the notification beep and the voice. I often cannot hear the voice telling me to walk or run.
Wmeoejn on 11/15/2017
Great workouts
Lemonaiding on 11/9/2017
More than halfway through and still training. Great App.
10K app
canela 1953 on 11/7/2017
I am 64 years old. Little over a month ago I could not run or jog for one whole minute. Today I was able to run for 20 minutes !!! Great app!!! Great program !!! Thank you!!!
Great running app
Keez12 on 11/7/2017
I found the verbal cues very helpful, especially the halfway done cue.
Fantastic App!
Azlaxion on 11/3/2017
I have been using this app to prepare for runs for a couple years now, and my runs keep improving. Easy to use, and no more shin splints since I started slowly.
So good...so far
BeFunkyFan on 11/2/2017
App seems to be working fine so far. It's only been two days. I'll come back to update in awhile.
Thank you! Easy, helpful, encouraging app. Keep up the great work!
Jamie Camie on 10/21/2017
Great app. Very easy to use, and almost identical to the C25K app. After I completed the C25K running app, it gave me the option to download this 10K trainer, the next app in the series. Once I did, instead of starting me at the beginning, the program started me at week 6, because it recognized I was already capable of the 5K. That was a great feature...it's a huge perk how all these training apps are from the same company, so they're all connected and easy to use. It still gives you the "one minutes remaining" audible announcement, which is handy. I like all the voice notifications (when to begin running, stop running, and when I'm half-way) because then I can just go and listen to music, without having to look at my phone. Thanks for the easy-to-use, beginning runner-friendly app! Combined with healthy eating (and minimal extra sugar and bread), I am in the best shape I've been in, in 5 years.
Good accountability, but a 1 minute run to start seems intense!
Odessa730 on 10/18/2017
I like this app for the gradual increase, but I think as a beginner, the 1 minute running during week 1 should have started at 30 seconds and gone up from there. Also, no verbal cues when my phone is locked.
Great app
Ott8788 on 10/17/2017
Getting me ready to be dead sexy!!
Helping me to my second 10K
Great for bus commuters on 10/17/2017
I didn’t know Couch to 10K existed, but I used the C25K app for my first 10K and found it to be really helpful. I was thrilled to have found C210K, and look forward to running my second 10K in a few days. Thanks for getting me there, app developers!
New mom jogger on 10/15/2017
Free portion is decent - not a lot of talk just quick instructions... don't know about the purchased side- I'm cheap... took off a star just because I think using the app interferes with playing my own music- I have to hit play for every single song- not easy whilst jogging and I don't usually have to do that if I'm not using this app.... otherwise decent app! We'll see if I can get to a 10K in this few weeks.......
Notifications problem iPhone
EastCoastJetski on 10/11/2017
Please update app so that it shows in my notifications settings for iPhone IOS 11. Also, please workout history view that includes distance, pace, and calories.
Best Work out app
Diva2720 on 10/7/2017
I've always wanted to be a runner. This app and the C25k app has been making me reach my goal. I am very satisfied with the pace of the app. I would recommend it for the beginner runner or anyone interested in training for a marathon
Good for a free app
Lambertval10634 on 10/7/2017
I'm not new to running but I needed a reboot so I downloaded this app...today was the first time I've used it and I was very pleased. It doesn't tell u the distance/pace without paying so from now on I'll wear my garmin as well but I did like the freedom of being told what to do and when to do it...not as good as a coach but hey coaches aren't usually free either lol
Great app!
JOBAFATT on 10/5/2017
Great app!
The finish line for running moved closer
Jjspencer on 10/4/2017
I once listened to a ted talk that said the difference between physically fit people and non physically fit people is that the finish line seems too far away distance wise for the unfit people which causes the brain and body to not like running... well with c25k and couch to 10K it feels like the finish line is a bit closer for us non physically fit people. I mean I have learned to breathe while running and the breaks and cool down periods in the app are awesome for beginners like myself. I'm happy a friend recommended I download this.
Great way to get back in shape.
googley4444444 on 10/2/2017
Timing and notifications from the app really help it's overall performance.
Needs Work
kisshusgirl on 9/28/2017
If i put it on the lock screen or go to a different app, it does not warn me when to start walking or running. Instead, it sends it as an alert. Very unhelpful!!
Love it!
T0oyett on 9/26/2017
Love this app. Easy to use!
Made it so easy
rdyyyyyyyy on 9/25/2017
After trying to start running dozens of times throughout my life, at 46, I was finally successful with the c25k app. Now a I've transitioned to the 10K app & I'm still improving. I love being able to listen to music or podcasts and get background guidance that makes improving my endurance effortless and helps my workout fly by.
