C25K® 5K Running Coach & Map

45
Value score / 100 Worth paying? No Skip it

C25K is a highly effective running program for beginners, but its value is significantly diminished by a recent shift to a paywall that restricts most of the program to paying subscribers, despite previously being free.

Free to download seen up to $74.99 4.8★ lifetime (170,035) since 2011

C25K is praised for its effectiveness in guiding beginners to run a 5K, with many users achieving their running goals. However, recent changes have placed most of the program behind a paywall after only a week or two, leading to widespread disappointment and frustration among long-time users and new downloads alike.

Free vs paid

The free version of C25K allows users to complete the first week or two of the program R3R4R7R20. After this initial period, users must pay a subscription to continue with the full Couch to 5K program R3R4R7R20. The paid version unlocks the entire program, and in some cases, additional features like detailed stats, music integration, and Apple Watch functionality R36R91R158R338. Some users report that even with a subscription, they still encounter ads and pop-ups R80R167R613R654.

Value complaints

  • The program, which used to be entirely free, is now largely behind a paywall after only the first week or two.R3R4R7R20
  • Users feel the subscription prices are too high for a basic running timer, especially for a program that was once free.R35R39R103R180
  • Even after paying or subscribing, users report still being bombarded with ads and upgrade prompts.R80R167R613R654
  • Previous lifetime purchases or bundles are no longer honored, forcing long-time users to re-subscribe.R99R127R158R169
  • Basic features like detailed run stats, history, and Apple Watch integration are restricted to the paid version.R36R91R158R338

Where it delivers

  • The program is highly effective and motivating for beginners, successfully transitioning users from not running to completing 5K distances.R1R2R5R8
  • The app provides clear voiceover instructions and paces users effectively through incremental intensity.R6R11R15R32
  • It helps users build endurance and makes long-distance running seem achievable.R5R18R25R50
  • Some users find the free features, like mapping runs and voiceover instructions, to be valuable for their initial training.R6R19R22
Worth paying if

It might be worth paying if you are a complete beginner who has tried the initial free weeks and found the structured program uniquely motivating and effective, and you are willing to overlook the significant price complaints and paywall issues R1R2R5R8.

Skip / stay free if

You should skip paying if you are a former user who had access to the full program for free, as the new paywall will be a significant disappointment R3R4R7R39. Also skip if you are looking for a truly free Couch to 5K program, as many alternatives exist R3R4. Furthermore, if you rely heavily on Apple Watch integration or detailed run stats in the free version, you will be disappointed and forced to pay R36R91R158R338.

Evidence note: The evidence is heavily skewed towards complaints about the paywall, indicating a significant negative shift in user perception due to monetization changes. While many positive reviews praise the program's effectiveness, these often predate or do not directly address the recent paywall implementation.

What reviewers actually said

Built only from these 120 real reviews (foreign ones translated). Superscripts jump to the quote here. Apple has no per-review links, so [ref] opens that app's reviews on the App Store.

  1. [R3] 2/5 · US Lame that you have to pay: I used this app years ago when the whole program was free. I'm getting back into running after a lengthy illness and I'm annoyed to see that you have to pay to finish the program last W2D1. I found another app and uninstalled this one.
  2. [R4] 1/5 · US Pay Wall smh: Of course just going along with the state of this greedy world. This app used to offer all weeks for free and really helped my running. Recommended it to a friend to find out that it only goes to week 2 then have to pay beyond that. There’s noone left who does things to genuinely help people. Everything is for a profit. Extremely disappointed and will NOT be recommending this app.
  3. [R7] 1/5 · US Program is now behind paywall: Used this app in the past and it was great. Disappointing to see that you must now pay after the first week.
  4. [R20] 1/5 · US Deceptive: They hide the subscription requirement well. I thought this was a free app, but it’s a one week trial. I thought the pro version was just to unlock additional features. Nope - you can only use it for one week, then you have to pay. I’ll be starting over with something else.
  5. [R35] 2/5 · US Paywall entire program?: I used C25K many years ago now, and while the program is great, returning to find they’ve changed their subscription model to restrict access to the entire program after day 4 is a laugh. Making one pay for advanced stats and access to their extra features made sense, but $30 for 3 months on… a 2 month program where the base thing you’re blocking is just a timer to tell me
  6. [R39] 1/5 · US Disappointed: Used this app for years. Came back to it needing to get back and shape. A once free app now cost $30 for 3 months.
  7. [R103] 1/5 · US Overpriced: $30 for 3 months or $40 for the year for a running app? Ridiculous.
  8. [R180] 1/5 · US Used to be great: This app used to be my go to for when I train. After the recent update you can no longer go past week 2 day 1 without subscribing for the pro and paying $6.99 a month. No thank you! Download an interval training for free instead.
  9. [R80] 2/5 · US Tired of the ads and upgrade harassing: I just want to use the app to run. It’s very annoying that every time I open the app or finish a run I get bombarded with ads to upgrade “opportunities”. I won’t be using this app past the first 4 weeks.
  10. [R167] 1/5 · US Subscribed: I subscribed to this, and I am still getting beat down with ads and popups to do more. Pretty lame.
  11. [R613] 3/5 · CA Too many ads: Too many ads. I just want to run. I hate that I have to pay more to find out my stats. It’s unfair. And because I haven’t upgraded I have all these ads that are distracting. I don’t want the fitness plan and I don’t want to purchase any music
  12. [R654] 3/5 · CA Walk-to-Run Good, General Programming Annoying: The workouts that get you running are great. For me, it’s pushing me hard enough to make tangible progress but still keeping it manageable so I don’t give up. The structure of this app makes it just like all the most annoying apps you have. Constant requests for reviews (clearly I have given in), constant ads that pop up before you workout, during
  13. [R99] 1/5 · US purchased the bundle with unlimited pass a few years ago, no longer honors it: i purchased the bundle with unlimited that contains all four apps. i redownloaded them to get back to running and tried to restore my purchases and the apps no longer acknowledge my purchase. they claim i have no purchases to restore.
  14. [R127] 1/5 · US Would give 0 stars if I could: When this app came out I paid for access to it. This greedy developer doesn’t seem to understand what lifetime access means. I now cannot access the rest of my weeks because they paywalled an app I paid for. This app used to be amazing before the developers became greedy and dropped support for their legacy app which is just so slimy and gross I would love to give t
  15. [R158] 1/5 · US Choose Another App: Some of the functionality outlined in the application description does not exist in the application. The interface is poorly designed and navigation is not intuitive. They stop letting you use an an application that you purchased full price, because they came out with a new subscription The following features do not exist in the application - no activity summary after a r
  16. [R169] 2/5 · US Another great app ruined by monthly subscription: Years ago I paid the one time fee to unlock the full app and purchased the marathon trainer as well. Now this app REQUIRES a monthly subscription to use it? Tell me how that makes sense. This app was so amazing too. I used all of their apps and trained my way up to running 3 full marathons in 12 months. Now I will tell everyone to stay away from th
  17. [R36] 3/5 · US Great on phone, crummy Ape Watch integration: If you use this app running outdoors, it works fine. Records everything properly, sends notifications to headphones, etc. However if you use it indoors on a treadmill it does not record distance or steps properly, and it does not share information with the watch. If you start the app on the watch it doesn't send notifications to your headphones and i
  18. [R91] 3/5 · US Stupid watch app, limitations, and confusing experience: In general, I love the couch to 5K app and the integration with RockMyRun. But the watch implementation is just not good. The app experience is confusing. You have to choose between managing your run on your watch which supposedly gives you better tracking data or on your phone, which allows you to play music and listen to a playlist while y
  19. [R338] 3/5 · GB Ok: Not very inspiring and disappointing that you can’t see your sats unless you upgrade.
  20. [R1] 5/5 · US Potato to 5k: Love this app
  21. [R2] 5/5 · US Great and helpful: Very easy and helpful app to get you training to get into running! Been using it for years.
  22. [R5] 5/5 · US Keeps me motivated: This app makes long distance running seem achievable and it is
  23. [R8] 5/5 · US Perfect for getting started: This app really is perfect to get started on your running journey. No matter what your running experience is, you absolutely can start with C25K. The whole point is to get out and START! Whether you find the first week hard or easy, just aim for what the prompts tell you, and you will progress quickly. Do what you can GUILT FREE, and just start with C25K!
  24. [R6] 5/5 · US Great app!: I love the free features, like mapping my run, voiceover instructions, and incremental intensity over the weeks. I just wish there were five days per level instead of three! I’m usually not ready to advance after only three repetitions.
  25. [R11] 5/5 · US Great app for beginner runners: This is a great app for people who are just starting to run. It tells you what to do and paces you so that you can work yourself up to running further longer. I love this app and I recommend it to anyone who is interested in running and maybe you just have never been a runner like myself, but you wanna start, this is the app for you!
  26. [R15] 4/5 · US Eases you into it!: The app is great it eases you into a 5 K! I wish, if you needed to repeat a week it saved your data. Instead it writes over it. Minor flaw and definitely got over it.
  27. [R32] 5/5 · US Great Start!: I like how it allowed me to pause in between so that I could finish all 30 minutes at my own pace for the first day.
  28. [R18] 5/5 · US Good will push you to your limits: It’s good for getting stamina
  29. [R25] 5/5 · US Change: There slogan “couch to runner” is true. When I first got this app I wasn’t sure what would happen but it has really helped me build my endurance specificly this app acts as your own coach and supports you. 11/10
  30. [R50] 5/5 · US Really Works!: I was a sprinter all my life, then I became a mom of 4. Wanted to get back into running but my body had changed. Never did long distances, I couldn't. Didn't think it would ever be possible either. But...with this program, it was. I've run in 6 - 5K's and I ENJOY IT!
  31. [R19] 4/5 · US Great: So far the free version is great! I’m two days in but I’ve used it in the past as well. This app is going to make all the difference in my return to my live of running.💕
  32. [R22] 5/5 · US Great Overall, just a few suggestions: I attempted a workout, but forgot to pause and end the session so it was marked as complete. I have no way to delete this "finished workout", and it just bothers me. Please add the option to change to attempted for situations like this. Everything else is fantastic, and I'm on the free version so that says something. Update: The devs responded quickly and ex
  33. [R261] 1/5 · GB Voice coach: Voice commands on my watch are inaudible when running Spotify app, followed all the support advice and it simply does not work, pretty ineffective app if I need to carry my phone around on my runs ☹️☹️
  34. [R576] 3/5 · CA Not very compatible with Apple products: This app does not work well with my Apple Watch. It does not record heart rate while running, only after the run has been completed. It also does not calculate calories burned accurately, it underestimates by quite a bit. Run is not included in your daily fitness log and Apple phone.
  35. [R365] 3/5 · GB Not so free app: I’m not sure the ‘free’ app can promise to get you to 5k if you have to pay to find out how far you run!?
  36. [R629] 3/5 · CA I’ve had better: This app works great in the sense that it helps you get started slowly. It lets you know when to run and when to walk. The pro version will give you kilometres run, average pace and time elapsed (the free version doesn’t). That been said, I’ve seen apps that break it down further, giving you both run and walk pace on top of your average pace. This app also doesn’t give you the opp
  37. [R845] 3/5 · AU You have to pay now?!?: I used this app years ago and it provided so much more info about your run ... now you have to PAY to get the most basic stats?! Pretty sucky. 😕
