# Mental Math vs Brain Personal Trainer LB

Mental Math and Brain Personal Trainer LB are too close to call on the numbers: across 6 compared parameters — price, update cadence, ads and in-app purchases among them — neither pulls far enough ahead to decide it. What separates them is feature set and interface, not measurable difference.
