MuscleMetria
A strength training and nutrition product for people who are tired of noisy, overbuilt fitness apps.
MuscleMetria is being shaped around a simpler promise: less interruption, less clutter, and a smoother
training rhythm for lifters and coaches. The public iOS app is live, Android is in closed testing, and
coach access is handled through direct trial authorization.
MuscleMetria 面向厌倦嘈杂、臃肿健身 App 的训练者和教练。它想解决的不是“再多塞几个功能”，而是减少打断、减少杂糅，让认真训练的人用起来更顺手。公开 iOS 版已经上线，Android 正在 closed testing，教练端通过私信申请试用授权。
