i would give a 5 except the food logging is very limited and i havent figured out how to add foods not in your data base. It makes it hard to get accuracy on something im paying extra for. Edit: I figured out how to log my food individually so 5 stars. Im learning alot about what to eat and what my ideal fasting window is for overnight.

Been using the lumen for over a year now and I'm impressed. I've been able to manipulate my diet in many ways very well using it. I think the goals you set for it are a little to broad though. I also don't agree with the protein intake when dieting with higher fat. I don't want to lose muscle mass. But overall very good app I will continue to use for tracking and what to eat and when.

Helps me to make more informed decisions about my food intake and what is actually happening when I don't, or do, follow my food plan for myself. I love that it gives recipe suggestions in the app to keep me on track. No more guess work. No more excuses that a "certain food is probably 'fine', to have 4 hours before bed." I can see clearly, now, that it is not. This system is definitely a lifestyle changer for the better. Not an immediate change,it's a learning about YOUR body whole process.
