  1. [R5] 10K Runner 5/5 · US Easy to use and exactly what I needed: After trying to get into running a few times and injuring myself purchased this app so that I can ease into a running routine. The interface is simple and easy to use and I can listen to my music at the same time while it gives me prompts as needed.
  2. [R6] 10K Runner 3/5 · US It’s Good, But…: I enjoy using this app and think it has the potential to be truly great. The interface is clean, the guided structure keeps me consistent, and the workouts are motivating. However, a few missing features hold it back from being as useful as it could be. There’s currently no way to indicate whether you’re running on a treadmill or outside, which makes tracking feel less accurate s
  3. [R8] 10K Runner 5/5 · US Wish I could give 10 stars: I love this app so much. I love that it takes it slow and if you need to redo a run it optimizes it for you!
  4. [R13] 10K Runner 1/5 · US Nothing without pacing advisement: Training means nothing if you don’t have advise about pace. This may as well be a zone 2 trainer
  5. [R3] 10K Runner 3/5 · US A touch buggy.: The app is not syncing with the days of the week. I set up the app for the three runs to be on Tuesday, Thursday, and Saturday. When I went to do my first ride on Tuesday, it had skipped ahead today too so that if I hit the start button, it would’ve been for run two not run one. Today is Thursday rather than being on run two for my Thursday run. It’s on run three. I went to use the
  6. [R14] 10K Runner 5/5 · US Best Running App: I have had this app for years and when I take a big break from running it is my go to app to get back into running. It takes all the thinking out of training so I can enjoy my run and slowly improve. Will use this app always!
  7. [R16] 10K Runner 1/5 · US Controls primitive: In this day and age, controls on apps are everything. I paid for this version, so it’s not because it’s free. It kept skipping segments of the workout and I couldn’t figure out why. Then I realized there’s a pause are the bottom with arrows on either side. If the arrow gets activated (which apparently doesn’t take much because even with gloves on (and no touch components in
  8. [R2] 10K Runner 5/5 · US Love this ap!: Every time I need to get back into running I use this ap. It’s a great transitional program that anyone can use!
  9. [R11] 10K Runner 5/5 · US Get the App - it works!: Love the app - it works . You make strides even without realizing it. Next thing you know you are running a 5k or 10k I started with 5k over 4 years ago Even with breaks in between, my lungs are way better than when I started . The thought of just running a mile used to exhaust me mentally- now I practically blink at one Great app and really helps you meet your goa
  10. [R15] 10K Runner 3/5 · US Gets the job done, but doesn’t sync workouts with Apple health: Using this app, I have had good success going from extremely unfit and unable to run for more than 5 minutes to slightly less unfit and able to run ridiculously slowly for 60 minutes. The timer and ability to adjust difficulty based on how workouts feel are great. You can listen to music or podcasts on your phone and the timer functio
  11. [R1] 10K Runner 1/5 · US Not free: Presents itself as free in App Store. After multiple screens answering questions it hits you with a cost.
  12. [R4] 10K Runner 1/5 · US Misleading “Free”: Giving a free 7 day trial for a 12 week running plan shouldn’t be listed as “in app purchases”. Once trial is expired an ad screen blocks you from further use until you either pay more monthly than for Netflix, or $40 for lifetime. App itself is good, but be honest upfront that this is a $40 app.
  13. [R7] 10K Runner 2/5 · US Not a lifetime subscription: The app was good and helped with 10k training…but after a year they wanted to charge another $40. The plan I chose said “lifetime subscription” and “one time purchase” I assumed that meant I would only need to purchase once and be able to keep the app active as long as I wanted. I never would have paid $40 for just a year of service!
  14. [R10] 10K Runner 1/5 · US Charged me for trial: I was offered a free trial for the app but after entering the trial I was charged $20 for my subscription the next day. I love this app and I would be happy to change my review when this is resolved
  15. [R51] 10K Runner 1/5 · US Zero support: The app is great until you need support. My runs have been failing to sync to my history from my watch to my phone. I’ve reached out to support in the 2 limited ways they offer, and zero response for almost a week.
  16. [R105] 5K Runner 5/5 · US Great support: I’ve used this app on and off for years and definitely appreciate the one time payment. I was having issues with pairing my Apple Watch and emailed over the weekend. First thing Monday morning I got a response that fixed my issue. I do wish there were more robust workout details and the Apple fitness pairing captured more information but I’ve tried many of the 5k apps and keep comin
  17. [R43] 10K Runner 1/5 · US Can’t use without paying: You cannot use this app without paying. It lets you do all the the set up. Then before you can use the 1st workout, you must pay
  18. [R45] 10K Runner 1/5 · US Scam: Advertised as a free app and after going through the whole setup find out you have to pay $40 to use it.
  19. [R21] 10K Runner 3/5 · US Difficulty syncing with watch: Love the app but does not since well with watch and runs a separate program if I start the program on my watch
  20. [R27] 10K Runner 3/5 · US Great program, poor metrics: The kaizen approach to reaching your goals really aligns with my approach to life in general. The app also provides great positive reinforcement. It falls short on collecting good performance data even when paired with an Apple Watch. The heart rate data is sampled so infrequently that it skews deceptively low. Cadence isn’t recorded at all. Pace also seems high, but i
  21. [R37] 10K Runner 2/5 · US Unimpressed: Im on week 2 of this app and though i get the prompts when my workout is complete it does not log miles nor does it show my calories burned on my apple watch. My location is on not sure what the problem is. Otherwise i like it. Just would be nice to know my distance
  22. [R69] 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.
  23. [R71] 5K Runner 5/5 · US This app is awesome!: I downloaded this app way before the pandemic. For one reason or another, I’ve always had to stop mid goal. But this app’s got my back. Music, the ability to track the progress. There’s no better way to start over!!
