At the foundation, the two companion apps are well-matched. Activity reports, calorie tracking, goal setting, achievements, exercise diary, inactivity alerts, water intake, weight tracking, reproductive health features — including period notifications, fertile window, ovulation and start date predictions — are all present on both. Crucially, both apps are free and ad-free, so there are no hidden paywalls or intrusive monetization to contend with on either side.
The divergence becomes apparent when looking at what the Huawei Watch Fit 4 Pro's app adds on top of this shared baseline. It supports route planning and navigation, music playback controls, coaching features, temperature tracking, and app personalization — none of which are available in the CMF Watch 3 Pro's app. Coaching in particular can meaningfully elevate the experience for users working toward structured fitness goals, offering guided feedback rather than just passive data logging. Route support ties directly into the watch's hardware capabilities and makes the app a more complete tool for outdoor athletes. Music playback control adds genuine daily convenience for workout sessions.
The Huawei Watch Fit 4 Pro holds a clear software edge here. While the CMF Watch 3 Pro's app is competent and covers everyday needs without friction, the Huawei's ecosystem is simply broader — offering more tools for training guidance, personalization, and active use during workouts. Users who want a richer, more interactive software experience will find the Huawei's app meaningfully more capable.
