[whowhatwhenwhere]

In my new job I have been give a team of app developers and in their downtime they like to create apps and see what happens....

I'd like to start a plan to develop a good app that is BB related. I know there are tons of gym apps out there but I dont think there are many that are great..

Id love to hear dome of your guys on inputs on what they dont have or should have....

Nutrition app?
Workout log app?
Supplement app?
Cycle app?

I would like an app that gives me macros and suggestions for the macros

Such as a full days macros and divide them for me and give me suggestions in meals
