Great app and keeps me on track!!

This is a pretty nice app and certainly keeps me on track. In the past, I've been pretty erratic with my running patterns. It has been my dream to accomplish a full 5k run. I always want to do 'more' and it burns me out. A friend recommended this app and I decided to go for it. I promised myself that I would follow it exactly. I have for the most part. In the earlier weeks, I did add on another 1 mile because when I follow it, it is only 2 miles. I prefer to run/walk at least 3 miles. Once the days became more endurance'ed, I follow it exactly. To this date, I've accomplished 5 weeks, 2 days. I was excited I could finally run 5 min at a time, now it's 8 min?!?! I repeated the 5wk,1 day two times then did the 5/2 and I MADE it. I love this feeling. I'll repeat 5/2 though... what the app could improve on is: the timer on the app and my treadmill seems to mismatch eventually. It lines up for a while then the app lags behind. I stick with my treadmill time as I got it timed perfectly. For example today is 31 minutes. I ended up walking 4 more seconds on the treadmill so it would 'finish' at the same time as the app. Another thing that needs improvement is the ability to log or track when I repeat days. I always feel bad when I have to click yes to 'are you sure, it will erase your data if you repeat' (not verbatim) but I did do these days very well but I just wanted to repeat these just to give me a little more time and build endurance.

We Can Do It!!! "2"

I am now on the end of Week 4 of the program. My weight had remained at a consistent rise of 2lbs and drop of 2lbs for the last 2 weeks;But after starting week 4, the pounds have started to shed again. 😭 I can't tell you guys how relieved I am to no longer be in a stagnant position, scale wise. On week 4, I run 3 min, walk 1.5, run 5min., walk 2.5 and repeat once. Today is week 4 day 3 and it was the first time I hit a runners high, ever! I ran the 3 minutes,then got halfway through the 5 minute run when it hit me. The pain and burning in my legs went numb, I no longer felt out of breathe, and just as I was about to hit the peak the timer dinged. So I stopped and did my 2.5 min walk. What was this feeling I just got a savor of? This taste of heaven?! The second 3 minute run came and the euphoric feeling I had only temporarily felt wasnt there right away, and the burn was back, but right as I was hitting the end of the second three minute run the high came back, so when the timer dinged to begging walking, I kept going for another 5 minutes. It was amazing. I don't even know if this makes sense, but I'm so tired I can't think straight lol. Totally recommend this app, can't praise it enough. Thank God for it!

Excellent training program, needs a little fixing!

I am currently on week 6 day 3 and I have gone from barely being able to jog for a minute and a half to running my 1st 5k (and not walking at all!) this past weekend. I am thankful for the progressive and easy training, however, at least once every 2 weeks the app decides to just... Stop working in the middle of my run. For example: I just completed week 6 day 2 today and that is 10 minute jog, 3 minute walk. The chime came on for me to begin my 10 minutes of jogging, but then never came on to change over to walking. When I stopped after jogging for something around 12 minutes (5 songs), I checked the app and it said I have only lapsed 6 total minutes! 5 of warm up and only 2 of jogging?! It was frustrating and this is not the first time this has happened. The app will quit itself if you lock the screen with it on, it won't play pandora through the app and constantly stops counting down or playing the chimes over my music. Most days, it's fine, but every 2 weeks it takes a total crap and doesn't work! Please fix these issues! I love the program otherwise.
