  2. [R8] C25K® 5K Running Coach & Map 5/5 · US Perfect for getting started: This app really is perfect to get started on your running journey.

  3. [R14] C25K® 5K Running Coach & Map 5/5 · US It works: Trust the program! Went from struggling to run at all to running a triathlon
  4. [R17] C25K® 5K Running Coach & Map 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!
  5. [R5] C25K® 5K Running Coach & Map 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.
  6. [R9] 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
  7. [R27] C25K® 5K Running Coach & Map 3/5 · GB Could be so much better: App works averagely but the user interface could do with improvement as could aspects of its operation. Buttons are too close together when saving runs from watch, I’ve lost several when trying to upload . Buttons for run sector are also too close together. It’s easy to select the wrong one and not realise until your part way through. The week and day lettering needs wor
  8. [R3] 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
  9. [R21] C25K® 5K Running Coach & Map 3/5 · GB Lost 10 mins of time!: Mission was to run for 20 minutes but after 5 mins warm up and 10 mins of running the app announced it was cool down time. Will retake this one and see if it works correctly next time. First time (that I’m aware that this has happened on my workouts)
  10. [R22] C25K® 5K Running Coach & Map 1/5 · US What’s up with the GPS signal???: Horrible GPS signal…..
  11. [R61] adidas Running 2/5 · US GPS is trash: GPS was weak and didn’t record my first mile which was probably my fastest mile yet. Very frustrating. I’m not a super star athlete but I do want to see my improvement. Nike app wouldn’t do me like this.
  12. [R30] C25K® 5K Running Coach & Map 3/5 · GB Get ready to pay!: If you download this because it says it offers an Iwatch app, get ready to have to pay a stupid monthly price to be able to leave your phone at home and run with your watch!!!
  13. [R58] C25K® 5K Running Coach & Map 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 ☹️☹️
  14. [R1] 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. [R4] 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. [R7] 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. [R10] 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. [R45] C25K® 5K Running Coach & Map 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
  19. [R55] C25K® 5K Running Coach & Map 4/5 · US “What’s New” Description: When you update the app for iOS, do you think you could modify the “What’s New” description? You haven’t changed its wording for two years. It looks lame, and it makes you appear lazy.
  20. [R64] adidas Running 2/5 · US The July 2026 30K goal is MIA: The July 2026 30K goal is MIA, and as luck would have it, so is the support and feedback page so this is the only place to report bugs.
  21. [R94] adidas Running 2/5 · US Support and some features disappeared: There is no longer an ability to report issues. Garmin activity is synced but the points stopped accumulating on 4/30/26 and 5/1/26. There is also no ability to upload a .gpx file anymore.
  22. [R66] adidas Running 3/5 · US New user experience: I’ve only logged a few runs. The app works well and I like the idea of getting club points for runs. I don’t like that the phone app has to run while using the Apple Watch to track runs. Can this be fixed so I can run without having to use my phone?
  23. [R73] adidas Running 2/5 · US Loved it, but now I’m frustrated!: I loved using this app for all sorts of activities. I used to get my heart rate with my Apple Watch throughout my workouts, while simultaneously using my Bluetooth earbuds to listen to music. No if I use my earbuds, I don’t get the heart rate reading anymore. I only get it if I’m not using anything else connected to my phone via Bluetooth. Not sure if it’s becaus
  24. [R77] adidas Running 4/5 · US Love this app...: Love 💕 this app! I would’ve given it five ⭐️ stars, if ADIDAS/RUNTASTIC would update software to use on my Apple Watch while working out outdoors without carrying iPhone AND making it available to set in my ‘complications’ face-watch! I’ve been using to track my inline-skating workouts! Very few workout apps are compatible (track and sync) inline skating. Thanks for that ADIDAS/R
  25. [R78] adidas Running 3/5 · US Great App But HR Monitor Broken Now: I love this app. Much better than Apple's default workout app and since I am an Adidas fan, earn points is a really nice added bonus while working on staying fit. Unfortunately, as of a recent patch, the heart rate monitor has stopped detecting anything on the app itself. HR monitor works fine in the regular workout app, so it's not a hardware issue. I have an
  26. [R70] adidas Running 1/5 · US Heart rate display and tracking stopped working.: It is not the watch or the setup as I have used the app for years and not made changes and the heart rate is recorded and tracked in my apple health partner account. Unfortunately, this is a necessity for me and if it’s not going to display, I can’t use it.
  27. [R76] adidas Running 2/5 · US Calories Tracker is Off: How is walking 3.5 miles at 4mph only tracking as 35 calories. When looking up my weight, height, and steps taken all other resources show I’m burning 160-180 calories
