I completed the Fitness22 5k and 10K trainers and those two apps were identical as far as I could tell (distances notwithstanding). This 21k trainer app not the same as those 2 apps. The audio sounds different (less crisp, I would say possibly even distorted), the cues options are different (no options for every 5 min. marks), and it doesn’t work on silent mode with your phone as far as I can tell. This app also recommends running-off days to do strength training and gives a couple of examples for workouts and if you have certain other apps of theirs it might sync with it (I don’t have those apps so I can’t confirm). If this were the 21k version of the 5/10k trainer apps, in my opinion it would be 5-stars. I haven’t completed this program yet but this far I’m not impressed. Will I continue with the app? Probably.

I’ve used the 5k and 10K and they were great but they haven’t synced this one with the Apple Watch so you have to carry your phone with you to run which doesn’t work on these longer distances as I’m carrying water etc. and I don’t do a big phone like this with an arm band. They would be 5 stars if you could use your watch. Same as the 10K pacer

Unlike previous versions of different distance trainers from this developer the audible cues in this version only work randomly. Unfortunately you have to carry your phone in your hand and constantly watch the timer.

The app is not compatible with Apple Watch and is doesn’t consistently save workouts.

Loved the 5k and 20k versions. The 21k version saves some of my runs but deletes others. I just finished a run, made sure it recorded and saved. Then I hard closed the app and the/opened. Run was gone. It has done this for most of my runs using this app.

Every day my progress is wiped clean, stats gone.

I never thought I could get into running until I found this series of apps. Started with the 5k and now here I am on the 21K. I never would’ve believed it. Try it!

I have used the 5k & 10K Runner and loved them. I recommend them all of the time to new runners. However, the 21K Runner is glitchy. I have deleted and reinstalled just to be sure it is up to date. 1. My runs are not saved. I will complete a day of a run and it’s is in my history, however when I return the next today to choose that days run or rest almost all the runs are no longer checked off as complete. I try to manually go back and enter that “Did It” and it appears to work until the next day and they’re all gone again. This is super annoying when you’re trying to stay on track and aren’t sure what hat day you’re on. 2. The voice prompts are glitchy in that they don’t always prompt during a run. Sometimes they do and sometimes they don’t. If it weren’t for my watch sometimes I wouldn’t even know there was a prompt. My ringer is not turned off so there isn’t any reason I can find for this to happen. 3. Unlike the other two apps there are rest days to check off. That is the most annoying thing. Especially when it doesn’t save that you’ve done it. Remove the rest days. Just instruct people to test every other day or do a strengthening workout on no run days but PLEASE remove the rest days. It feels inconsistent and I know there is a method for short run, interval run, long run. Knowing this helps me plan my runs but it took me too long to figure out the rhythm because of the rest days and random 2 days of rest which I really dislike. As I said, I loved the previous app but this one isn’t working out like I’d hoped and I am on the lookout now for a better one.

This app worked great for a while but the last two weeks, every single run gets deleted so I have no way to track overall miles or see my run history, I’ve reached out through the app support team multiple times and have not heard back

Love this app. Got me to my goals
