## What is Mulbyul?

Mulbyul is a dry-training routine app for freedivers.

Build repeatable hold-and-rest workouts you can do on dry land — like CO2 tables — run them with a step-by-step timer, and log every result. Organize the routines your coach gives you or the ones you do most, and watch your progress day by day.

■ Your own training routines
· Combine hold and rest steps to build exactly the routine you want.
· Save coach-prescribed or go-to routines and start them in one tap.
· Or jump straight in with the built-in preset routines.

■ Step timer and contraction logging
· Follow your routine through its rest and hold phases.
· Tap once to mark your first diaphragm contraction during a hold.
· Record both your target and actual time for every set.

■ Routine generation and sync
· On supported devices, draft a CO2-style dry-training routine from a single line of text.
· Routines are stored on device and can sync via CloudKit depending on your Apple account and iCloud setup.

■ Safety first
· A safety notice appears before every session.
· Stop immediately if you feel dizzy.
· Never train in water alone.

■ Track and reflect
· Log target time, actual time, and contraction timing for each set.
· Review past sessions and plan your next one.

■ Made for
· Freedivers doing dry training at home on weeknights
· Students following a coach's routine consistently
· Anyone who wants to track their breath-hold progress properly

Build your training, one session at a time, with Mulbyul.

Note: Mulbyul is a tool for dry training in a safe environment. Never practice breath-hold training in water without a qualified buddy.
