  1. [R2] 5K Runner 4/5 · US Great but wish for more: I have used other apps that did the same thing in the past. This one is definitely one of the best. The lifetime pass is a good deal as well. But I will cancel now that I reached the end of my trial. The good stuff: - I like the questionnaire that dropped me in the middle of the program. Other apps force you to start at the start. - The app also asks you how the run went
  2. [R5] 5K Runner 5/5 · US You’ll love it!: This program is great at progressing you in a way that makes you succeed. I’m technically done with the program but I still run with it every single time.
  3. [R14] 5K Runner 5/5 · US Bought Once in 2017- Use Every Spring to Ease Back Into Running: I bought this app years ago, and I always come back to it in the spring. I do a terrible job of keeping up my cardio in the winter, and this app helps me ease back into my running workouts without going overboard. This app pre plans running workouts for me, making it harder for me to cut my runs short if I were to be in charge. Defin
  4. [R20] 5K Runner 5/5 · US Used it twice: I’ve used this program twice and had great results both times. The first time I was already pretty fit and was able to advance quickly through the program due to the optimization. This time I’m postpartum and pushing a jogging stroller and going at a bit slower pace but still having great results with my cardio endurance. Worth it!
  5. [R1] 5K Runner 1/5 · US Misleading: Waiste of time . Pur all your information in and then hit a paywall
  6. [R4] 5K Runner 1/5 · US It used to be worth it…: I used this app back in 2019 to get ready for my first 5k. It was only $12 for 12 weeks which was great. It also offered a couple different options for different prices. Just redownloaded it and not only did they get rid of the options but now it’s $50! Definitely not worth that much. On to a different app…
  7. [R7] 5K Runner 1/5 · US Not the same.: Used to use this app all the time. It was free to use the first 2 interval programs unlimited. Now you can use it free for 2 days then take your wallet out.
  8. [R3] 5K Runner 3/5 · US It’s okay: I wanted to like it but it seems pretty lacking in features. The main problem for me is that it doesn’t sync well with the Apple Watch and iPhone, I can start on my iPhone but it will not stream the run to my watch.
  9. [R6] 5K Runner 3/5 · US App is good when it works: If this app was free I wouldn’t complain but this app will often fail mid workout and stop tracking completely defeating the purpose of the app and ruining your workout.
  10. [R9] 5K Runner 3/5 · US Great for 5k training, but lacking: Overall I like the app, but no ability to use other music platforms (Spotify) and no way to see pace is a bit of a miss.
  11. [R18] 5K Runner 3/5 · GB Great for the first 8 weeks: Thai app was great for the first 8 weeks but then once completing the 5k challenge I decided to continue with the apps workout programme. For what ever reason these weeks do not support use on an Apple Watch so back to having to table my phone with me on my runs. Very annoying!
  12. [R30] 5K Runner 2/5 · US W7D2: I was supposed to have a 20 minute run and after 5 minutes it said I had completed my 20 minute run. I restarted the run and it did the same thing again. Very frustrating
  13. [R10] 5K Runner 1/5 · US Not free: It’s not free at all
  14. [R61] C25K® 5K Running Coach & Map 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.
  15. [R64] C25K® 5K Running Coach & Map 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.
  16. [R67] C25K® 5K Running Coach & Map 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.
  17. [R70] C25K® 5K Running Coach & Map 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.
  18. [R63] C25K® 5K Running Coach & Map 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
  19. [R69] C25K® 5K Running Coach & Map 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
