WorkOutDoors is a deep Apple Watch tracker with near-unlimited screen customization. GPS accuracy matches the watch chip. No audio coaching, no structured plans. It is a tool for people who build their own process. The standout feature: any metric on any screen in any font size, something Garmin does not allow. The entry cost is high: setup takes hours and documentation is sparse. The Bluetooth device limit (2 devices) is a watchOS system constraint, not an app bug, but users do not distinguish between the two.
評価点：Full freedom to arrange workout screens, large fonts for poor eyesight, support for external heart rate sensors, long battery life on long runs
不満点：Very high barrier to entry: the interface requires deep study before the first workout, routes must be imported from third-party apps, settings reset after updates
向いている人：Experienced runners and triathletes with Apple Watch who need maximum data customization and do not want coaching.
An aggregator app: reads workout data from Apple Health and visualizes heart rate zone distribution over a week and year. It does not record workouts itself, it is an analytics layer on top of other sources. Great for monitoring zone balance at a glance, but watch-to-iPhone mirroring broke after version 9.0.2 and has not been fixed for months.
評価点：Weekly and yearly zone breakdown in one view makes it easy to see whether you have enough Zone 2 or everything went red. Works on top of Apple Fitness without duplicating workout records. One-time purchase instead of a subscription.
不満点：Watch-to-iPhone mirroring is broken since version 9.0.2, the flagship gym feature is unavailable. Does not read heart rate outside recorded workouts, so casual activity is not counted. No deduplication when multiple data sources overlap. Support does not respond to emails.
向いている人：Regular athletes already recording workouts in Apple Watch or Garmin who want to see heart rate zone balance without manual counting. Not suitable as a primary running app.
The core idea is right: C25K directly on Apple Watch with no phone needed. But audio cues do not work with AirPods via the phone, haptics are too weak, and the timer sometimes freezes. The program itself is solid.
評価点：The workout runs entirely from the wrist, you can leave your phone at home. One-time payment. Route and per-km pace are shown right in the summary.
不満点：Audio cues do not play through AirPods Pro when music is coming from the phone. The haptic signal is so faint it is not felt while running. Units (km/miles) reset to default on every launch.
向いている人：A runner who wants to leave the phone at home and get all cues from the watch, and who can live with limited stats.
A log hub for experienced runners focused on analytics: cumulative graphs, intensity calendar, segment splits. Active development appears to have stopped and some features moved behind a paywall without warning.
評価点：Cumulative graph and calendar-view intensity are useful for planning ultra distances. Pace breakdown by segment. Apple Watch integration out of the box.
不満点：Development is effectively frozen: tag and sync bugs have not been fixed for months. No Garmin integration. The WorkoutKit builder does not support power alerts above 240W.
向いている人：An experienced runner or ultra-marathoner on Apple Watch who needs accumulated volume analytics, not a plan from scratch.
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.
