4★Loved this app! Would be 5 stars if they hadn't taken away the back button and hidden the scan button in a menu. Don't give me more steps to get to what I need. Also, so many items have the wrong info and it's a pain to try to fix it. Otherwise, the app is helpful and I like it. Update: One button to open scanner. Thank you! Upgraded to 4 stars.

5★This is a great app if you are trying to follow a strict diet. It's super easy to use, just look up a food you ate and add it to your meal (breakfast, lunch, dinner, and snack) and it calculates the nutritional info for you and keeps a daily log. It has every kind of food with all of its nutrition info, and you can add it by weight or piece(s), and it even has fractions from 1/8-7/8. You put in your goals, and you can plan your meals, look up recipes, add exercises, and even daily water intake!

5★Best FREE functionality and features for calorie, carb, fat and protein tracking! I've tried many other popular meal tracking apps, Carb Manager gives you the most features for free if you're looking to track your meals. Other apps want you to pay to use the barcode scanner or create custom foods, not Carb Manager. Of course if you want advanced features you can choose to pay for them. I've used the free version for over a year just to track calories and protein intake, simple, no complaints.

4★I like it, but when you create a workout, it enters twice. when you delete one, both are deleted. also when creating another, the time and calories burned are the same as the created workout entered before. I won't do premium until this is fixed. EDIT PER DEVELOPER RESPONSE: they responded within a day and gave me some options to engage with more specifics. Regardless of the eventual resolution, awesome customer service. Thanks Wombat!

4★The latest update you added scroll entry rather than typing it in, which makes entering the data extremely time consuming. The developer stated the other setting was still there and it was (yay!). The macros pie chart is a great at a glance for keeping your P/C/F on track. I would give 5 stars if it didn't focus on reducing carbs - but alas, it is a keto based tracker so I get that. The dancing avocado should be for keeping under kcals rather than carbs.
