I’ve never used Macrofactor so I can’t make a great comparison, the only commercial calorie tracker I’ve used is Lose It.
Major differences would be:
The food database - I don’t know what Macrofactor uses but I use Open Food Facts and the USDA.
Manatee Fitness has zero monetization. No subscription, ads, or tracking. I never want to have access to my users data.
Macrofactor likely has a much more polished UI. I do my best but I’m far from a professional designer.
Presidential primaries are the weird ones because they’re spread over all the states. Otherwise candidates just need to do whatever to get on the ballot(usually gather signatures) and then win the election. Parties can throw their weight behind one candidate in particular but that’s not the same as declaring a winner. AOC got into Congress by beating a party backed incumbent in a primary.
