A Runna author writes that marking a run “too hard” did not change the next session. It helps to show how the feedback was taken into account and what can be changed by hand.
A structured training planner focused on "what to run today" with schedule adjustment. Strong on weeks-ahead planning and real-time pace cues. Weak on adapting the plan to feedback, GPS sometimes differs from Garmin by 400 m, and support is lacking.
評価点：A clear training calendar removes the "what should I run today" question. Speed up or slow down cues delivered mid-run. Moving days around without losing progress. Users who started from zero run 5K nonstop within a month.
不満点："Too hard" or "distance too long" feedback does not always change the next session, the plan keeps increasing load. No injury pause mechanism, vacation mode is a workaround. Audio coaching lowers music volume and never restores it. A run accidentally pauses in a pocket with no warning.
向いている人：Runners with a base fitness level preparing for a specific race (5K, half marathon, marathon). Those who want a training block structure, not just run logging.
A primary GPS running tracker with training plans and audio coaching. Conceptually strong, but persistent GPS accuracy issues consistently hurt the experience.
評価点：Guided runs with a coach voice hold your pace and keep your mind engaged. Race-specific plans (marathon, 5K) are structured and progressive. Progress tracking is clear.
不満点：GPS periodically loses up to half a mile per run, especially when paired with Apple Watch. Completed runs sometimes do not register in the plan. Auto-pause triggers during a run with the screen off.
向いている人：Beginner and intermediate runners who want a structured plan and voice guidance with no subscription fee.
A full-featured running tracker with route history, shoe tracking, and training plans. Degraded in sync quality after the ASICS acquisition.
評価点：Shoe mileage tracking is a feature that is hard to find in competitors. History filtering by duration and date is handy for race prep.
不満点：Apple Watch sync is unreliable: pausing on the watch does not carry over to the app. The transition to ASICS deleted some users' data without warning.
向いている人：Regular runners who track shoe wear and prepare for races based on their history.
A dedicated multi-sport GPS tracker focused on community and segments. The running side is solid, but GPS accuracy is unstable on hikes.
評価点：The KOM/QOM segment system adds competitive context even to solo workouts. The social feed with friends' activity creates a genuine sense of community.
不満点：GPS on a hike sometimes cuts 13 miles out of 20, which is a critical gap. Privacy defaults are opaque: activities are public by default and users are not warned at setup.
向いている人：Runners and cyclists who care about segment competition and social context. Not suitable as a primary hiking tracker.
A reliable progressive couch-to-10K program with a clear walk/run interval structure. Plans are time-based, not distance-based, which disappoints more experienced users. Adapts to how you feel, but offers no pace guidance, no progress reset, and no flexible goal setting.
評価点：The walk-to-run interval approach gradually builds endurance without overloading. The app offers to repeat a failed workout with adjustments based on how you felt. Audio cues do not interrupt music. Proven mechanics: users come back after years-long gaps.
不満点：The program runs on time, not kilometers: you finish "10K" having actually run about 5.5 miles. No pace recommendations, the plans do not explain how fast to run. You cannot reset progress or change your goal mid-course. On-screen buttons for pause and skip activate accidentally in a pocket.
向いている人：Beginning runners with no base who need a clear multi-week structure, not free tracking. People recovering from injury or a long break.
