Here are issues my clients had with this app. Every time I take a pic of my food I would have to shut my phone off and restart for the app to work. I have issues uploading the photos of myself. Also sometimes if I took a photo of my food outside of the app, it wouldn't upload. Sometimes when posting food photos it would say there was an error so I’d reupload. Then the photo would show up twice. I took all my photos and it only uploaded one, I retook them and then it only uploaded a different one. Third time was a charm but it froze in the process! In the beginning I would put in my measurements late on the monday and it would record them as the next day in the summary line, but when I clicked on them it would say the right date. Couldn’t upload photos from “photos” I posted my photos at night, but when I opened the app this morning to take a photo of breakfast, it showed a loading symbol, crashed and then it shows the photos as submitted today 😞 Timeout error when trying to upload photos. I put one of my measurements incorrectly. Can we update? The app isn’t letting me change my initial entry? Can’t seem to be able to correct any mistakes with an entry. I have just noticed that when i take the photo from the app it hasn't saved. I lost yesterday and my picture of the 800g plate this am. It seems to save ok when i take the pic on the iphone then upload it though. How does the leader board work? I'm particularly confused by the measurements one. *(Must of our clients found the leader boards confusing, especially the measures) trianing videos unclear on any of these boards. My app seems to be stuck on Thursday 9th so my photos are logging in for Thursday instead of Friday. Any suggestions? yesterday my username name and password weren’t visible. But I was still able to login. Today, the options to upload photos isn’t appearing. So my app won't accept the progress pics but it does take the meal pictures.. any ideas how I can add day 1 progress photos? (He was doing it correctly) ### 2/5 — Glitchy *2020-01-07* From my iPhone I cannot log manual workouts, the measurements area is hit or miss (sometimes the section doesn’t pull up )& It’s difficult to hit the correct spot to enter measurements & login is required each time I open the app. ### 1/5 — Very buggy and stressful to use *2019-08-30* This app has a lot of bugs. It’s very stressful to use, and I don’t recommend it. The workout feature says it syncs with HealthKit, but only one has synced correctly out of several attempts. I attempted to use the manual activity logging, but it doesn’t work either and throws weird error codes. In the progress photos area, you cannot load a photo from your camera roll. Also, the nutrition tab allows you to upload photos of your meals, but half the time it doesn’t work. ## Most critical reviews (10 lowest-rated) ### 1/5 — constant crashing *2024-12-08, version 1.6.80* I’m sure the app would be great to use but it keeps crashing — can’t even login ### 1/5 — Still crashing and not updating *2023-06-03* The App crashes for me every day. It also keeps saying it needs an update, but then when you go to update it, there’s no update. As I’m reading the other comments, I am seeing that this is not an isolated issue, but several other people are going through the same thing. Extremely frustrating!!!! ### 1/5 — Crashes every time I try to load photos. Very frustrating *2023-06-01* Crashes every time I try to load photos. Very frustrating ### 1/5 — Crashes…bugs…. inaccuracies. *2023-01-16, version 1.6.68* Possibly the worst app I’ve ever used. It crashes on a daily basis, several times a day. Have contacted Help/Support in their chat and did not hear back. Difficult to login. Only syncs and posts about 50% of your workouts. Most of them over 24 hours after the fact. Difficult to contact support as the app crashes almost every time. Don’t waste your time with this one. Worst app ever. ### 1/5 — App needs effective update *2022-09-22* This app has some difficulties with the measurement section. There’s 6 areas where you can input your measurements of body. When you enter on the 3rd area, it freezes and app no longer functions/ crashes. And measurements are not saved. Frustrating if you’re trying to track your progress. ### 1/5 — App is awful *2022-08-30* It continues to kick me off in the middle of a workout. No place to check for an update to install. I continue to loose workout data/tracking due to the continuous dropping. Very frustrating ### 1/5 — The app keeps crashing and is consistently having issues *2022-04-08* I belong to a gym that uses this app and I keep encouraging them to switch to an app that actually works. It is frustrating to be in a challenge at the gym and not being able to measure your workouts and end up losing the challenge because of an inferior app. Today the app would not launch even after I tried uninstalling and reinstalling the app. Even rebooting my phone did not make it work. ### 1/5 — Updated and now it’s crashing *2022-03-10* I try to sign in and it starts loading then crashes. I’ve uninstalled, reinstalled even signed out of Apple ID and turned off phone to no avail. Just want the app to work so I could record my workout 😖. Will update review once issue is fixed. ### 1/5 — Worst app ever *2021-08-04* I feel like I am a witch doctor practicing voodoo w this app. Over the last 4 days it has mysteriously worked twice. Every other time it crashes or does not recognize pw. Someone needs to work the bugs out of this thing! ### 1/5 — Very buggy and poor app *2019-12-11* I have the heart rate monitor and app for my hiit gym. However, the body metrics has stopped working. I click on the body metrics area to manually log weight or sync with a scale and it just freezes. Overall the app feels like it’s pretty poorly put together. ## Most praised reviews (10 highest-rated) ### 5/5 — Lost 5% Body Fat in 6 weeks *2023-08-31* Unbelievable, I know. Mind you, I’ve been really fit off and on my whole life. The last last injury sidelined me. I got chubby; and was miserable. I started using this app at the recommendation of a colleague. I’ve always been great with exercise: consistency, intensity, and duration. (Unless injured). My week point? I love food. I cook really healthy food. But? I was eating too much. The app had me take pics of my food, and it made me accountable to someone on the other end. It worked. The Challenge was like a contest… which I can never resist. It worked like crazy. 5% body fat reduction in 6 weeks. Wowwww! Mind you, I have always listed weights. So? My muscles hypertrophied pretty quickly, because they were already there… just shrunken from disuse. Anyway. I love the App. LOVE IT. I did have a few technical issues. But? That’s how I roll. There tech support is awesome! ### 5/5 — App crashing! *2020-06-13* I see that it was updated five days ago. I used it yesterday with no issues, but today every time I click log in, it crashes completely. I wasn’t able to use it for my workout today. :( Otherwise, I love this app. That is why I still give it five stars! ### 5/5 — This app saved my business *2020-05-20* Our chain of 3 health clubs love the virtual coaching capabilities that the app provides for our members. Thanks to CorSync our business is able to survive this crazy pandemic. The app is easy to use and our members love it. Thank you!!! ### 5/5 — So motivating and easy to use! *2020-05-20* I am a big fan of the NuvitaCorSync app. It keeps me accountable to my fitness goals and focused on bettering my health! It’s very user friendly and so fun to use. Highly recommend using this app! ### 5/5 — Want to see how hard you’re working out??? *2020-05-14* Love my app! I feel a real sense of accomplishment if I workout in and above my zone and if I don’t I’m motivated to work harder!!! ### 5/5 — Love CorSync *2020-05-14, version 1.6.26* Huge difference with accountability for my Clients. Personalized guidance, from a certified exercise physiologist and nutritionalist! ### 5/5 — Sooo Motivating *2020-05-14* Working out at home with my coach keeps me motivated. She’s always giving me feedback on my meals and nutrition which keeps me on track. Best App! ### 5/5 — Holds me accountable *2018-12-17* I love this app & the scale. It keeps me connected to my coach and a community! Loving my results so far! ### 3/5 — Says update available- but there isn’t one *2023-06-04* Won’t sync with body comp scale. Heart rate monitors are tiny and must go on forearm which is awkward when working out. Terrible experience so far. ### 3/5 — Update pushed only crashes *2021-03-09* So it won’t open it just crashes. It said update, so I did and now it won’t open at all. --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
