| First of all, congrats on the launch! As it is a somewhat cornerstone of your pitch, I can't help but comment on the use case. For the simple reason that any person's gut microbiome - which varies considerably and is the focus of intense research as too little is yet known - both consumes and modulates the processing of calories, counting calories is generally considered bad science and an entirely ineffective way to measure, guide or sustain a healthy lifestyle [1][2][3]. Personally, I think unless you're diabetic, in which case you'd anyway rely on an entirely different monitoring/ tracking system, it's just a whoefully ineffective KPI. Most people today for example rather grossly undersupply fiber.
If an app could deduce contents of calories, fiber and fat contents of a meal and track healthy composition/ supply for each, that would truly support a healthy lifestyle. 1: https://www.health.harvard.edu/staying-healthy/stop-counting... 2: https://www.scientificamerican.com/article/science-reveals-w... 3: https://www.aims.ca/op-ed/calorie-counting-bad-science/ |
I agree having a compulsion to weigh everything you eat for fear of "failing" isn't very productive. But on the other hand I think there is genuine utility in knowing roughly what percentage of your daily energy comes from your typical breakfast / lunch / drinks / dinner / snacks etc etc.
Where I feel my approach beats the typical calorie tracker is that it doesn't encourage micro-counting or even reaching a specific goal, but rather just keeps you informed. This makes it very easy to know where your energy came from and thus gives you power to increase / decrease as needed.
Definitely take your point on the other factors - but for many people, I think, it would help knowing what a maintenance day of eating looks / feels like.
