4.2 out of 5
Doesnt work

5Kto10K does not work at all. The couch to 5k app works amazingly and this wasn’t next step. This version is still completely outdated, the GPS works but in the log your pace averages don’t actually match up. It keeps telling me my average running pace is something like 3.5 minute or 5.5 minutes which is impossible for me especially considering it’s giving me the correct distance over the run. I also know for a fact that I average a 10 minute mile. I have emailed support several times and they keep giving me the run around like asking me to run in a more open space. I run exactly where I ran every day using couch to 5k with zero problems. They need to just stop avoiding it and update 5Kto10K. I’m very much a person that’s motivated by forward progress and 5Kto10K not working has definitely slowed down my progress. I will likely switch to a different app for my 5k to 10K training after I back peddle trying to get my 5k time back up after having so many glitchy disappointing runs with 5Kto10K, my progress has digressed. Really disappointed and even more annoyed that customer service is putting the problem on me.

Music Not Working Properly

I completed the couch to 5k app and loved every minute of it. I decided to continue with my training and I am not a fan of the 5k to 10K app. I was hopeful it would work the same but the layout is different, it’s not easy to share your progress on social media, and the music player does let work correctly anymore. My music won’t sync correctly with my phone. My playlists are mislabeled. I have to search around to find my running mix. Please please fix this bug. I can’t run without music and I like to sync it with 5Kto10K so that I can hear the trainer when she talks to me.

Disappointed

I love the Couch-to-5k app! It works really well and has continually been updated over the years to maintain the high quality.

5k-to-10k, however, is really a let down. When I first used it a few years ago I liked it but it doesn’t seem to have been updated since. The distance I run is always significantly off. It cuts my five minute cool-down off after about one minute. The voice prompts don’t work consistently. After completing the first three weeks of the program, I’m ready to start over with a better 10k training app.

Please fix the bugs

I love the program and log, however, 5Kto10K itself if very difficult to work with. Each time I exit 5Kto10K to change my music it stops my workout and wants me to start over. Also, I wish there was an option to turn off the trainer and just use the timer. I use another app to actual map out my runs and distance and in the past with the 5K trainer was able to use both at one time, but I can’t with this one. It’s very frustrating.

Too finicky to be useful

5Kto10K requires you to have your phone with the ringer on, screen permanently unlocked and only works with Apple Music. My phone has been on silent since 2012, and if I run with my screen unlocked, I’m begging for issues (workout paused, skips ahead, skips back, etc). I don’t care about not being able to use other music apps as I use Apple Music but I care very much about having to use it within 5Kto10K which means I can only listen to my playlists and in the order I put them together, not shuffled. The workouts are good and offer a great variety, but if I have to follow all these rules to get to them (and then they might be skipped around) what’s the point? I’m not bothering with contacting support.

I just use Garmin Connect to build workouts lifted directly from 5Kto10K . At least then I know I won’t have any issues.

Please fix the bugs!

I L-O-V-E-D the couch25K app. Completed it & enjoyed getting healthier. I’m absolutely BAFFLED as to why this follow-up app is so dysfunctional. It constantly notifies me to turn on “background app refresh” in settings when the background app refresh is already on and my phone is fully charged. The whole point is to have a little coach in your ear when you’re running, but it doesn’t give audio cues unless you have the phone open in your hand, and the music doesn’t play properly. I’m guessing the dysfunction is related to the background app refresh” bug, but I’m not a programmer so what do I know? I also really liked the variety of coaches (Zombies & Unicorns!) on the C25K app & would like to see that added as well. I just know I want 5Kto10K to work as great as C25K did. Dear Active, Please, Please, fix it!!!

FIX THE BUGS!!!

When going from network to Wi-fi, 5Kto10K will crash every time. When trying to open the community tab, it crashes every time. This is so frustrating! I absolutely loved the C25K app, and can’t understand how this one has so many issues!!

For the person above me that’s having issues not hearing the coach...push the lock button in the top left corner. It will keep it on top regardless of the error.

In-run audio cues only work sporadically

I like a lot about 5Kto10K. I was satisfied by the training content itself. But a HUGE drawback was the failure of the audio cues. They only worked at the beginning of the run, sometimes at the end of the run, but only VERY rarely during the workout. This was very frustrating. From reading other reviews, it doesn’t sound like this is a new problem. Until this gets fixed, I’m using another app.

Doesn’t go through entire session

Recently finished couch to 5k. Started this one, but noticed it doesn’t take me through the entire time. Example, I’m on week one, workout 2. It is 5 min warm up, 10 min jog, 3 min tempo, 10 min jog, and 5 min cool down. It started with the 5 min, 10 min jog, but it only went 1 min tempo and went straight to 5 min cool down - even the 5 min cool down cut off before the time was up. This cut my time and distance down and was unable to meet my goal for today.

Needs voice commands

I like 5Kto10K for the over all use, but couch to 5k is much better for over all feel. 5Kto10K doesn’t tell you what you should be doing inside of the run. Let’s say you’re supposed to do a 10 min jog then a 7 min tempo run, but then a 10 min jog. It will tell you to start your first jog, but a voice won’t tell you to do the tempo or the second jog, it sends me a notification. But no actual voice tells me what to do.

Not as good as the original

Couch to 5k is a 5star app, this is a solid 3. It has bugs, for example I just set a new best pace but it still has an older run set as best pace even though I knocked 40s off the time.

Also the audio cues DO NOT WORK while in the run. 5Kto10K says you need to turn off vibrate only and adjust the volume but that doesn’t fix the issue. And it’s not an issue in the first app so why would it be in this one?

Also the resolution is different, almost zoomed in more or something. Overall, 3 stars... I’d pay $10 to have 5Kto10K exactly like the first.

Good app but has some minor bugs

I really like 5Kto10K and went through its predecessor, Couch to 5K, but it does have some bugs. The voice coach only speaks at the start and end of the workout rather than at transition points. The Watch app was disabled, so hopefully it’s being fixed.

Good app

I really like 5Kto10K! I finished the couch to 5k app so wanted to keep going. Found this one, which was by the same company. The couch to 5k app is much better bc the background refresh works in that one and there are more coaches to choose from (I miss the unicorn!) I did find a work around to the background refresh by keeping it open and on and just locking it, so that has helped tremendously!

Good App

I like 5Kto10K, it is very good at getting you to be a better runner. It’s challenging for someone that does not like to run and wants to start. I know 5Kto10K is for people begging to run longer distance than a 5k, but more information while running would be good at this point. Tell the time you have left in a section is useful & not just “you are 1/2 way”. Also, how fast your running pace is, would be good so when you are supposed to run faster “tempo run” or “fast run” you know if you are pushing yourself.

It’s okay

It’s an okay app, but I wish it were updated like Couch to 5K. I’m sure that one is far and away more popular, so that one gets more of the developers’ attention, but it wouldn’t take a whole lot to make this one better. I’d appreciate some definitions here since I’m not super experienced in running other than C25K. Is there a difference between a jog and a steady run? What’s a tempo run? How much effort should I be exerting during a fast run interval? I know I can wing it and it will probably be fine but I’d just like more information available through 5Kto10K .

Love this app but one minor annoyance

Overall, I’m a big fan of 5Kto10K. I got started with the Couch to 5K app which was perfect. This one is almost as good, though there is one problem. When I am running, sometimes you cannot hear the coach prompting you to alter your pace throughout the work out. I’m not sure why that is but it can be a little bit annoying because you have to check your phone from time to time. I think this happens when the screen is off but 5Kto10K is still running.

Other than that, it is a great app. Hopefully they can fix this.

So good I wish they had a half marathon app!

I always hated running. In high school I ran a 15-minute mile. At the age of 30 I started using Couch to 5k and saw great results. I was able to run my first official 5k in 32 minutes after finishing the program. I bumped up to this 10K program and the results are getting even better. The tempo runs and fast runs are killer at first, but they improve your overall endurance. I’m in week 6 and I’m sure I’ll hit the 10K mark by week 8.

5/5 for 5 to 10K

I was such a fan of the “couch to 5K” app! It made it easy to get back into running into really do it at a pace that was comfortable for me. I was really happy to learn that they had another app to help me continue my process and ultimately achieve my goal of running 1/ half by my 40th birthday October 2021! Do you self a favor and download both apps! Do you want regret it.

Love this program!

I’ve used the couch to 5k app to get back running after pregnancy and injuries, and now I’m using it to build up endurance for longer distances. I love that it eases the runner into safe progression.
I would like to see:

More integration with treadmill. When I manually add my distance it gives me a pop up that my stats are erased. This is ok as I track stats with other apps.

More coaching during the run. For instance, I was distracted at the beginning of one of my runs and missed the instruction for what a tempo run is. As someone who didn’t do track in high school and basically just goes out and runs I don’t know what some terms are. I would have liked that instruction in my ear as I ran.

Regardless, I feel like this is a safe progression that will keep me from being injured by overdoing it! I have recommended the couch to 5k to new runners and I’d recommend this one too!!

Not “couch” to 10K but close

5Kto10K is great. I thought it was a couch to 10K and was surprised by having to run for 30 minutes straight on day one! It was just what I needed though, and I did it and I felt good and I’m still going here in week three! I love not having to think about anything other than my pace and route. The jog setting has a red color against a black screen that is hard to see in sunlight, but that is my only complaint. Thumbs up!

Features

Constance, Billie and Sergeant Block are back in this follow-up to the award-winning Couch to 5K® training app (2012 Appy Award for best Healthcare & Fitness app).

Without granting notification permissions, during a workout you can click the lock icon at the top left to keep the app active and still hear the coach.

Continued use of GPS running in the background can dramatically decrease battery life.

To save your battery, 5K to 10K sends audio notifications when your screen is locked or another app is in use.
