I’d say a good app gives you that extra motivation, support, helps you track your progress, and that makes you even more motivated. There’s seriously tons of apps out there. I personally use Unimeal https://www.trustpilot.com/review/unimeal.com. It’s got meal plans, a calorie counter, and my fave thing that's a water tracker. Obviously no one’s gonna drink the water for me, but it’s super satisfying to drink a glass and check the box that says "another one down." So yeah, I think you get what I mean.
