Features
Built around one routine, done right
EMST Timer handles the counting and timing so you can focus on your breathing.
Text you can actually read
Large type, high contrast, and big tap targets on every screen — nothing to squint at.
Guided by voice, not just the screen
Clear voice and visual cues walk you through every inhale and exhale, so you always know what's next.
Timing handled for you
Rest between reps and rest between sets count down automatically. No stopwatch, no counting in your head.
Rate each rep with one tap
A simple happy or sad face after every rep — nothing to fill out, nothing to type.
A record of every session
See a full 5×5 result grid for each session, saved right on your device — so you know exactly how it went.
Built for landscape
Prop your phone up and glance at a clear, wide display throughout your whole session.
