What we keep seeing
Guessing macros is leaving lifts on the floor.
Most lifting apps stop at the rep counter. Most nutrition apps stop at calories. The middle is where every PR is decided, and it's where most lifters are flying blind.
Protein floor missed
Without a daily target visible at meal time, 60% of lifters undershoot their grams by 20% or more.
No ratio control
Calorie-only logs hide a bad split. You can hit a deficit and still leave size on the floor.
Logging breaks at the gym
Typing macros between sets does not happen. If logging requires a keyboard, it does not get logged.
