GymSetSense+Hiit — Smart Gym Set & Rest Tracker
· v2.3
About
The gym timer that knows when you stop lifting. GymSetSense+Hiit watches your heart rate and switches to rest automatically, no buttons, no fumbling mid-workout.
GymSetSense+Hiit turns your Garmin into a real strength-training partner.
Most gym timers make YOU do the work. GymSetSense+Hiit uses your heart rate to detect when a set ends and starts your rest countdown automatically. Chalk on your hands ? Mid-superset ? It just works.

SMART SET TRACKING
• Auto-rest detection: senses when a set truly ends — wrist stillness AND a real heart-rate drop, together — and starts your rest countdown automatically, with Low / Medium / High sensitivity (can be disabled)
• Long-rest option for compound lifts: arm a longer rest with one button press before a heavy set; short rest stays your default otherwise
• Soft "still going?" buzz after 5 minutes of continuous work — a gentle nudge, never forces a switch
• One button (LAP) to switch Work ↔ Rest manually any time
• Every set saved as a lap in your FIT file, plus a real Sets count in Garmin Connect's activity detail — see per-set HR too
• Set counter with accidental-press protection and undo (DOWN)
• Experimental rep counting from wrist motion (optional)
LIVE DATA THAT MATTERS
• High-contrast white data screen built for bright gym lighting
• Big HR in a zone-coloured box (your personal zones from your Garmin profile)
• Session max/avg HR, per-set max/min HR, native Garmin calories
• Rest countdown with 10-second warning buzz + full-width rest sweep bar
• Body Battery on the start screen so you know how ready you are
• Inactivity reminder if you've been chatting instead of lifting
FINISH YOUR WAY
After the gym session, pick what's next right on the watch:
• Treadmill run — pace, distance, HR zone gauge, then a guided 90-second cooldown showing your live HR drop
• Tabata HIIT — adjust work/rest times right on the watch before each block (no phone needed), configurable rounds, each round a lap
• A 5-second get-ready countdown before a Run or Tabata starts recording — buzz at 5s, beep 3-2-1, stronger buzz at go — so you're never caught mid-step. Skip early with START, cancel with LAP
• Or just save and go — every block is its own activity in Garmin Connect
MADE FOR REAL GYMS
• Buttons-only control — sweat and touchscreens don't mix (touch can only pause)
• No phone needed in the gym — 100% standalone on the watch
• Featherweight on battery: a full 45-min gym session plus a 30-min run used just 2% on a fenix 7 Pro
• Nothing recorded until you press START; discard protection on every exit path
• Pause anytime (gym or run): START pauses and resumes, LAP finishes, DOWN discards
• Battery guard force-saves your workout before the watch dies
• White, Dark, or Auto theme (dark after sunset) for menus and summaries
• Adjustable vibration strength, optional tone alerts
• 10 languages

What's new
## What's new (v2.3)
The biggest update yet — smarter detection, new controls, and a fresh look:
• Auto-rest now needs BOTH your wrist going still AND your heart rate dropping before it ends a set — a quick re-grip or breath mid-set no longer cuts it short
• New long-rest option for compound lifts — press UP mid-set to arm a longer rest for the set you're about to finish; short rest stays the default
• Soft "still going?" buzz after 5 minutes of continuous work — a gentle nudge, never forces a switch
• Set count now shows up as a real stat in Garmin Connect's activity detail, not just unlabeled laps
• Tabata work/rest times are now adjustable right on the watch before each block — no more digging into phone settings
• New 5-second get-ready countdown before a Run or Tabata starts recording — buzz at 5s, beep 3-2-1, stronger buzz at go
• Refreshed design across every menu and confirmation screen, in both Light and Dark theme
• Pause now also pauses the FIT recording, so Garmin Connect's activity time matches the watch
• Smoother treadmill run pause/resume, cleaner lap buzzes, wider rest-countdown bar
• Wider device support — 60+ Garmin watches now, including Instinct, older fēnix 5/6, D2, Descent, and more Forerunner/MARQ variants
## What's new (v2.2)
Driven by real on-watch testing:
• Smarter auto-rest — now senses set-end from wrist motion as well as heart
rate, so it triggers even when your HR barely moves during lifting (the old
HR-only detection often never fired). New Low/Medium/High sensitivity setting.
• Pause the run — START now pauses and resumes the treadmill run instead of
jumping to a save prompt; LAP finishes, DOWN discards. Gym and run pause the
same way now.
• Run screen numbers stay inside their cells (pace/distance no longer overflow).
• One clean buzz per km/mile (was a burst), and the treadmill auto-pause no
longer flap-buzzes when your wrist cadence dips.
• Rest countdown bar now sweeps the full width of the screen.
