I wouldn't use this. It's not that I don't think your calorie count might be right for some cases, but it won't get everything right, and when you're trying to lose/gain weight, making sure you have accurate calorie counts is crucial (you need measuring spoons/cups, etc).
Which is why I'm sticking with MyFitnessPal. Also, I find that although it's tedious to keep count of calories in the beginning, once you get used to it, it becomes a game, and even fun.
This feels like this fills the void between people who don't care about calories and people who really care about calories. I know people (read: myself) who are too lazy to measure everything down the milligram and just want an order or magnitude sense of calorie intake.
I agree that this can be useful for this use-case. Right now I'm bulking so it's more important for me to have a general "good estimate" of my calories and macros over a week, rather than a hyper-refined daily view, where I need a granularity of 100 calories or I haven't lost weight that day.
For my situation, it's more about "damn, I ate 1000 calories over last week, oh wow lol it's because I got super stoned on friday and ate half a pizza, ok, so next week eat 2 eggs instead of 3 for breakfast to make up for it." This app definitely wouldn't work for a cut, though, because I need my measuring cups and spoons to do that right.
With Bitesnap, you can enter exact cups, ounces, etc. if you want to refine your calorie estimate. One of our goals was to build a flexible tool where it would be quick to get a ballpark number, but also possible to get a very precise number if you put in just a bit more effort.
We think that the visual side of things will be useful to many people, even with ballpark calorie estimates. It's a great way of developing mindfulness of what you’re eating and improving and maintaining your diet.
Also, as we have been working on this it’s been a really fun game to see what we can recognize!
