Very effective program, atrocious app

First-off, I’m a big believer in the Naturally Slim program. It’s science is sound, and it’s very effective. I’ve personally lost over 35 lbs so far, yet I’ve found it to be very easy to do and live with. I wholeheartedly recommend it to anyone, especially anyone like me who has been struggling with my weight my whole life.

That said, this app, which is a necessary component of the NS program, works like it was developed as a student project. Every time they release an update there are more bugs. They have had problems with videos not being able to play, and with the latest update I was completely unable to log in for days. I still have problems uploading pics to my food diary. The app doesn’t function at all without internet; what if you’re eating and trying to log a meal where you have no internet service? Their support staff is also slow and indifferent in responding to all of these problems. Customer satisfaction is clearly not a priority.

Videos will not play in app

I am unable to watch the videos on the app on my iPhone 8plus. I tried several times, to no avail. I contacted customer support and the answer was completely impersonal and no help. I deleted the app and reinstalled it. It still does not work.

My husband is also signed up and we are able to watch the videos on his phone. I understand that technical issues happen, but was less than impressed with the unhelpful response suggesting that I try to watch them on another device.

I am also sharing this review with my insurance company that provided the access to this weight loss program.

Great program, app needs work.

I love the program and it’s principles, but the app needs some attention.
When you open it, a video is playing in the background and it seems to slow it down. It takes a while to think about asking for your passcode and there doesn’t seem to be an option to remove that security feature. When tracking food, there is an option to take a picture of your meal, but when I do, it takes so long to process it that my food is cold by the time I get to it.
