Ratings and reviews

Idea good, app sucks. When I first installed the app, there was a today page and a history page where I could log and access information. Those disappeared. Now it is only the AI interaction. Tech support replies with sympathy, but no help. There's no place to tick off the macros eaten for the day. Don't do what I did. Definitely do not get more than one month at a time if you decide to go beyond the free week. I didn't think the app could get worse. This is a new experience.

I've only had this app for one day. So far I like it, but I signed up for the subscription and I expected there would be a place to tick off my servings of each macro using the hand measurements. Wouldn't that make the app just great??? I'll update as I continue to use the app and monitor my results. Update: The functionality is not there. Major disappointment in an app that could have been very helpful.

I love Precision Nutrition as a brand, as a knowledge base, as a community. They have a significant impact on my learning curve in nutrition and their calculators are the best. The app has a very cool design and structure and there's a lot of potential here. Yet, it's overly simplistic - basically, it's a calculator and an AI combined, with a reminder that encourages habit reinforcement. I think this tool is still in development phase and it isn't worth its price now.
