## What is Calmset?

Calmset gives you one thing and does it well: precise rest timing between sets, based on exercise science.

Rest periods matter. Too short and you leave strength on the table. Too long and you lose the metabolic stimulus. Calmset takes the guesswork out with evidence-based presets tuned to your training goal.

EVIDENCE-BASED PRESETS
  • Strength: 3–5 minutes — full phosphocreatine recovery
  • Hypertrophy: 60–90 seconds — optimal metabolic stress
  • Endurance: 30–45 seconds — sustained cardiovascular demand
  • Set your own duration with Pro

  GUIDED BREATHING BETWEEN SETS
  • 8 structured breathing patterns during rest intervals
  • From quick activation to deep recovery
  • Each pattern grounded in peer-reviewed sports science
  • Visual breathing guide synced to your rest timer

  WORKS WHERE YOU NEED IT
  • Background and lock screen — no need to keep the app open
  • Apple Watch companion with guided breathing
  • Live Activity and Dynamic Island support
  • Haptic and sound alerts when rest ends

  MULTI-SET TRAINING
  • Queue sets and let the timer count them down
  • Auto-advance moves you through sets hands-free
  • Weekly Pulse — training summary with week-over-week trends
  • Session history to track rest patterns over time

  DESIGNED FOR THE GYM FLOOR
  • Dark, minimal interface — reads clean between sets
  • No account required. No data collection.
  • No ads. No subscriptions.
  • 14 languages supported

  CALMSET PRO — $4.99 LIFETIME
  One purchase. Yours forever.
  • Unlimited sets per session
  • Custom rest durations
  • Auto-advance between sets
  • Live Activity and Dynamic Island
  • Apple Watch companion

Built by a sports physiotherapist with over a decade of clinical experience. Proper rest between sets is one of the simplest ways to improve your training — and most people get it wrong.

## Version history (last 2 releases)

### 1.0.1 — 2026-04-24

Apple Watch got a big rework. iPhone's more stable too.

  Apple Watch
  • The timer runs on the Watch itself now. No more waiting for the
  iPhone to catch up.
  • Wrist down and rest ends? Your Watch taps you on time.
  • Digital Crown picker for custom durations, right on the Watch.
  • Delete saved presets from the Watch too.
  • Pro actually reaches the Watch now.

  iPhone
  • Buying Pro is solid again.
  • Dynamic Island and Live Activity keep the timer visible with the
  phone locked or in another app.
  • Quieter home screen between workouts.
  • Home's mode row is cleaner. Just the four scientific presets now.

  A lot of this came from folks telling us what was rough. Thanks.
