Nothing to save first. • Create, edit, duplicate and delete your own workouts. VOICE AND SOUND CUES • A voice announces every stage and counts down out loud. • Or whistles and beeps, from a set of built-in sounds. • Count down your way: every second, every n-th second, or only the final seconds. • Edit what the voice says (PRO), or bring your own sound files (PRO). LIVE BLUETOOTH HEART RATE + ZONES (PRO) • Pair any Bluetooth LE chest strap or armband (standard Heart Rate Profile). • Live BPM while you train — current, min, average and max. • 5 colour-coded zones from your age or your own max HR. • Every session saves your full heart-rate curve, coloured by zone and drawn over the stages you ran. HISTORY AND PROGRESS — FREE FOR 7 DAYS • Automatic history of every session: date, duration, rounds, calories, completion. • Streaks, a calendar, weekly trends, personal records and a weekly goal. • Time in each heart-rate zone, per-workout history, notes and RPE. • Export your history as a CSV file. • Both screens are open for your first 7 days, then they are PRO. BUILT FOR IPHONE AND IPAD • A Live Activity on the Lock Screen and in the Dynamic Island: current stage, time left, and pause, back and skip without unlocking. • Full-screen colour-coded stages, a big readable timer and a "next" preview, in portrait or landscape. • Skip a stage, go back a stage, or hold to rewind and fast-forward. • Keeps running with the screen locked, and plays over your music. • Weekday reminders, so a training day never slips. • Back up your workouts to a file and restore them on any device — including workouts exported from Caynax HIIT elsewhere. WHAT IS HIIT? High-intensity interval training alternates short, intense effort with less-intense recovery. A typical session lasts 9-20 minutes: a warm-up, six to ten hard reps separated by easy recovery, then a cool-down. A common protocol uses a 2:1 work-to-rest ratio — 30-40 s hard, then 15-20 s easy. It is one of the best ways to get a complete workout when time is short. Because of the intensity, this training is not for everyone. Please consult a doctor and a qualified trainer first. PERFECT FOR: Tabata • HIIT • cardio • CrossFit-style circuits • Fartlek • kettlebell • jump rope • bodyweight • running intervals • boxing rounds • stretching • yoga • and anything else that needs a flexible timer. FREE vs PRO Caynax HIIT is free and fully usable: unlimited workouts, work up to 3 min, recovery up to 5 min, 1-20 rounds, voice and sound cues.
