Great So Far

I’ve been using this app for a couple of weeks. Last time I counted calories was in the Fitbit app. This app is much nicer and more user friendly, in my opinion. The food database isn’t quite built yet but you have the option to submit a public entry for all to see; meaning the more people submit, the more the database builds. However, there are still pretty good amounts of foods there already. The only thing I find frustrating is that everything is measured by “OZ” (especially 1 OZ) or “G” and it would be nice to have more options such as “1 cup” or “1 bag” or “1 sandwich” that can be filed under the respective nutrition counts. Maybe I’m missing something? However, that is not enough to make me give up on YAZIO. I LOVE the Siri shortcuts that have been built in, and I use the “add water” shortcut daily. It makes the tedious efforts of the whole idea so much more convenient. I’m looking forward to sticking around and seeing how YAZIO develops.

Not ready for the iPhone X

I’ve used a few calorie counter apps before, and this one seemed good at first. However, there are a few options that are not user friendly. I have the free version so they may be better on the subscription version.
But, for one it’s hard to determine exactly where it is deriving the caloric limit from and it doesn’t automatically update with weight loss or gain, you must manually recalculate each time. Then, it doesn’t tell you the exact calories you have expended for the day (even wearing an Apple Watch), it just gives you a goal to burn each day based on information entered in to the bio.
I have yet to determine what the color of the circle for each day indicates since there is no explanation for that.
Also, I’ve yet to come across any of my foods that have the barcode information entered into their food database. A lot of the foods I'm scanning are common foods. It’s extremely time consuming and frustrating to have to enter all the information about every ingredient in each meal in manually. It also only gives a few options for serving sizes instead of multiple options. Most of the serving sizes on the packaging of my foods don’t even match up with one of the serving size options given.
Lastly, the app crashes on my iPhone X every time I try to search for a food. This is by far the most frustrating issue I’ve had with it. If it crashes every time I try to enter my food, how am I supposed to actually track my calories?

Developer Response ,


Please note:
Due to a bug which we had in the iOS app, the barcode scanner didn't search for the correct barcode number. Therefore, no results were shown in this case. We've just fixed that with the version 4.8.4.

Sorry for the inconvenience!

We'd be glad if you try our app and the barcode scanner once again. :)

Best regards,
your YAZIO team

Good, but needs work with the food database

My main gripe with this app is that the food database makes things more difficult than they need to be.

It’s very small, and usually the entries that are there are just plain wrong. About a quarter of the time I just fill out my own entry, which only adds to the problem because now there’s another entry and unless people look up the nutrition info they don’t know which one is right.

Also you can’t change what the app considers a standard portion, it’s stuck at oz by default. For example, I recently added 7-Eleven’s Chicken Dippers to the database. The 7-Eleven website lists the portion as 1 piece at 70 calories, one piece being 24g. When I entered the food I set the standard portion as 24g and even set up another portion as 24g labeled “piece”. When I finished the entry the default portion is labeled as oz and defaults to 1oz, which is slightly more than one portion. You can still change it to 1 piece and have the correct info, but the default being wrong might confuse users.

Other than that the app is great. I don’t have problems with step counting like I do on other apps, and the UI is clean. I also appreciate not having to create an account, I’ll give it five stars because I believe the database problem is fixable. Although seeing reviews here with similar problems from a year ago doesn’t give me hope.
