1.9.2

1.9.1

  • Starting a workout is much more reliable. The app decided whether the treadmill was ready from a status reading that could be older than the Start it was judging, so a belt that was already moving — or a machine still reporting its previous state — could stop the start from going through. That reading is now dated, and a belt already in motion is allowed to finish the handshake.
  • If your treadmill drops its Bluetooth connection mid-run, the workout now resumes by itself once the machine comes back. Only the automatic-pause half of this had ever actually run; the resume half could never be reached. The app now recognises the pause it caused itself and resumes on evidence from the machine in front of it, rather than guessing.
  • The speed picker follows the speed range your treadmill actually reports instead of assuming a fixed lower limit, with unit-aware bounds so machines that report in mph behave correctly and any clamping is visible rather than silent.
  • The speed and incline pickers now open on the value you are currently at, instead of jumping to a default.
  • Steadier Bluetooth connections: each device is checked once when it connects, with a single owner for post-connect discovery, and a service lookup that fails still answers instead of leaving the connection half-configured.
  • Better background battery behaviour: with no workout running the app now genuinely goes idle instead of keeping its Bluetooth notifications alive, and an intentional idle disconnect no longer looks like an unstable link that needs recovering.
  • Rating how hard a workout felt is now a clear ten-point scale you tap directly, and the Effort and State of Mind prompts on the summary are properly translated in every language.
  • The orange used for metrics now has a light-mode value that actually meets contrast requirements — it previously fell well short of them and was hard to read on a bright screen.
  • Your Apple Watch no longer beeps every thirty seconds when you have deliberately declined an optional Health data type. Body-measurement types are now an explicit opt-in rather than something requested by default.
  • Saved shortcut lists are treated as your stored settings, so they no longer shrink to whatever the currently connected treadmill reports.
  • The workout screen's Start button now honours your "Use Apple Watch" preference, and Apple Watch options no longer appear on devices where they don't apply.
  • Workout data mirrored from the Apple Watch no longer discards a batch silently when it cannot be read.
  • Starting a workout from the Watch re-checks whether one is already running on every retry, so a run can't be started twice.
  • Refined labels and translations.

1.9.0

  • Family Sharing: the subscription and the lifetime unlock now come in Family versions, so one purchase covers up to five family members. The individual tiers stay exactly as they were.
  • Monthly payments with a 12-month commitment on the yearly plan — pay a smaller amount each month instead of the whole year up front. Requires iOS 26.4 or later, and isn't offered in the United States or Singapore.
  • The Track view now runs counter-clockwise from a start line at the bottom right, the way a real athletics track does, and the lap fill ramps from dim at the start line to full colour under the marker.
  • The Home screen now tells you how many free workouts are left this month, with a direct way to unlock, and warns you when Health access is missing so a run can't silently go unrecorded.
  • Your treadmill's manufacturer and model now travel with your workouts into Apple Health, read from the machine's own Bluetooth device information.
  • You can delete a saved workout straight from the Sessions list.
  • The music player now hides itself when nothing is playing, instead of showing controls that can't start anything — and reappears on its own when you start a track.
  • On iPad: workout charts open as a pushed detail view instead of a sheet, and the Watch Status section no longer appears where there is no Watch.
  • Better battery behaviour: the app stops retrying its Bluetooth connection in the background when no workout is running.
  • Calories are now disabled when they aren't coming from the treadmill, with a clear explanation, and Health permission warnings tell you when data may be missing.
  • Fixed a case where finishing a workout you meant to discard could still save it to Apple Health.
  • Fixed treadmill speed showing a wrong value on some machines (including the BowFlex T6) after an unsolicited target-speed message.
  • Fixed Live Activity text that was hard to read in light mode, a Watch summary title that clipped in German, and several Apple Watch mirroring issues around cancelling and ending a workout.
  • Refined labels, plurals and translations.

1.8.5

  • More accurate elevation gain and floors climbed on treadmills that report incline — the elevation baseline now sets correctly the moment the incline reading first appears, and re-anchors itself if a bad reading slips through.
  • Steadier running cadence, so your steps-per-minute reads true instead of drifting or jumping.
  • On the Track view, the position marker now moves smoothly between distance updates instead of hopping forward in steps.
  • More reliable iPhone and Apple Watch mirroring, with fewer false connection-stalled moments and a cleaner recovery after a genuine disconnect.
  • Refined labels and translations.

1.8.4

  • Added a running-track view that maps your distance onto a stadium-style track and counts completed laps as you go.
  • Added support for body temperature sensors: connect a compatible Bluetooth sensor to track core and skin temperature plus heat strain during workouts — great for heat training.
  • Some treadmills — including KingSmith WalkingPad models — can now report their own step count using the FTMS standard step-count extension. Enable it for your treadmill in its device configuration.
