1. 3/5needs more food options

   i used this app for a while and it was great!! my only complaint is that the food options are very limited, and they don’t have many cultural dishes. I’m filipino, and live in a filipino household so i’m eating cultural food close to every day. It’s really frustrating when the main point of this app is to log your meals, when most of the meals i eat are on here. a lot of the time i’d have to literally write out every ingredient in the recipe. for this reason i have deleted the app, and i’m probably just gonna use fitbit instead. but if you’re someone who eats basic dishes then this app should be good for you!!

2. 2/5Great app until it just failed on me

   I have been using this app for almost 2 weeks now and it has been great. The tracking is so helpful and they give great nutrition tips. Today I tried adding a snack to my tracking and it wouldn’t load or let me add. I kept resetting my phone and then I finally deleted the app and downloaded it again. I tried ti get back in and all my data was gone and it was a completely new account even though I used the same email. I tried logging in and out and it would just show me a loading screen and never fully log in. I’m so mad all my data is gone and all my meals from the past weeks is deleted. I loved this app and it’s features were so good compared to others but it completely disappointed me.

3. 2/5Not User Friendly, features??

   A few things here…I chose this because my previous app had too many features. I want to count calories and restrict my diet. I like to go on a very strict diet for the first few weeks. I do very well on 1100 calories, and even 900 when I’m doing some fasting. This app doesn’t allow me to restrict my calories at all below 1200. I understand that it’s trying to keep me from being unhealthy, but it’s MY call. I don’t need a caloric big brother/babysitter. Furthermore, I could not find a way to do anything. I couldn’t figure out how to use the non premium version? I expect ads for the premium version but it wouldn’t let me do anything, at all, except take me to websites. Overall: no thanks! I’ll go back to my previous one that had too many features.

4. 2/5I wanted to like it

   This app has the potential to be so much better than it is. I have used other food tracking apps and this is definitely not as easy as they were. I like that it’s simpler, but it could be made better as far as adding foods and adding the same foods you eat often. I shouldn’t have to find the food, hit add and then hit add again to make it show up for the day. Also when removing you have to hit remove then save it at the end. Unnecessary. I should babble just to remove from the main screen. If you are using the app on more than one device it takes a long time to update to the second device. Also unnecessary. Someone who actually uses the device needs to help with changes.

5. 4/5Decent

   Decent app to track calories and set goals. Needs refining, the recipe builder doesn’t allow you to set portions. So if you build a carnivore bread it only allows you to select the whole thing or fractionally when you add it to your meal plan not by gram, oz, or anything else like when scanning a barcode. Has a robust library of foods to choose from, and it even appears to be other user input ones as well, but many common things are missing like high protein yogurt from friendly farms to name one. The “Ai” is a pretty good catch all but also gets the data wrong and when added to a meal it doesn’t let your select the unit of measure like mentioned before. Adding other diet plans would be nice too! Carnivore diet could be an option and while it’s pretty basic (meat, protein, fats) there are quite a few recipes that can be used to help out newer people. It’s a good platform but could easily be a top rated contender if they came in cleaned up some stuff.
