I inadvertently signed up for Premium and am unable to cancel. Even though I did not choose metric my stats are in metric. ## Most critical reviews (10 lowest-rated) ### 1/5 — Broken *2025-04-02, version 1.12* Daily activity will stop if you move off app to play music or any other source. It is horrible for tracking time for the day. ### 1/5 — Definitely not for a couch potato *2020-12-06* Says couch to 21.1k but first workout is a 40 minute run. Seriously!!! ### 1/5 — Useless *2020-04-22* Rubbish app ### 1/5 — GPS NOT WORKING *2020-04-14, version 1.6* GPS not working. I purchased this app about one week ago. I am running it on iPhone 8 IOS 13.3.1. I’ve check location services and made sure the app has access to GPS twice. I’ve deleted and upload on two separate occasions. The voice cue tells me my “pace is 0.0 meters..” I have learned a great lesson with this app: “Never buy anything before trying it”. I will not be continuing my subscription with you. Unfortunately I have paid for one year. ### 1/5 — Can’t change level *2020-04-06, version 1.3* I’m a “premium” member but can’t change the level of training. I reached out to app support but haven’t heard back. I can’t use the app because I shouldn’t be training at the defaulted level. Frustrating! ### 1/5 — Does not work *2020-03-14* Expensive but wanted to motivate myself. It does not work in several ways. Music not working, distances incorrect and duplicate runs in the logs. Avoid ### 1/5 — Doesn’t track your workout *2020-01-26, version 1.3* This app does not track distance and will randomly end the workout and restart it without warning so the log has multiple workouts for the same day with different times. It also doesn’t tell you when the workout ends. This app is in serious need of major updates. I did 2 workouts with it and the same problems occurred with both. I deleted it after the second workout. ### 1/5 — Needs improvement *2020-01-22, version 1.3* I only completed 1.5 workouts with the app. I didn’t like that even on the treadmill setting it did not record distance nor was there a way to edit the distance after having completed the workout. I could live with it and just write down my mileage in the comment nbd. However, my 2nd major red flag was during my second workout. I wanted to use my timer setting to do timed splits. After about 15 minutes of splits, I switched to this app which I assumed was continuing to run in the background but no time had passed. I continue toying with switch app to app. My treadmill and watch time said 35 minutes had elapsed, but this app said only 15 had elapsed (my warmup). Paused in the middle of the workout to delete and just rely on my watch. ### 1/5 — Disappointed *2019-10-09, version 1.2* The app will not track my distance. It is only good for the timer nothing else will work ### 1/5 — Audio issues *2019-04-09, version 1.2* When you have music on it has an automatic audio reduction. I went in settings to change it but then the app shuts down in the middle of your workout ## Most praised reviews (5 highest-rated) ### 5/5 — great app! *2020-03-13, version 1.3* I like the badges and challenges. I have to admit tho, the badges are kinda ugly haha and i wish they were better looking :p. That is just being picky tho. It is a great app! Edit to update: ### 4/5 — Phone calls *2022-04-22, version 1.8* I love the app, but I do wish that when I answered a call it wouldn’t pause. I always forget to start it back and lose time. ### 4/5 — Not so bad so far *2021-01-17, version 1.7* I just started using this app. So far so good. ### 2/5 — Needs work *2020-01-07, version 1.2* The meal plan is horrible. Not one meal have i seen that looks appealing WHATSOEVER. There is no setting to set what type foods you’ll eat, it just assumes you’ll eat what it says. The setting page won’t scroll and you can’t see all the settings. App stops timing in the middle of the workout. Needs an update very bad! Will update if changes are made but right now 2 stars is being generous! ### 2/5 — Needs help *2018-09-17, version 1.0* I don’t like that you can’t set your race date to customize the training program to a shorter training period. --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
