Want to burn fat, build stamina and get more out of every minute? High-intensity interval training alternates short bursts of all-out effort with brief recovery ā a flexible approach to challenging cardio sessions, even when you have only a short time to train. Caynax HIIT keeps the timing, the cues and the tracking for you, so you can focus on the work.

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).

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 iPhone or iPad ā including workouts saved from Caynax HIIT. 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 ā 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. PRO unlocks intervals of any length, up to 60 rounds, all spoken texts, your own sounds, the advanced countdown options, live heart rate, and History and Performance for good. Optional one-time PRO purchase, no subscription ā plus a cheaper "remove ads" option if that is all you want. Download Caynax HIIT and turn any space into your interval gym.

Verdict
The clearest difference is in-app purchases: EMS Mobile Virtual Coach at none against Caynax's 2. EMS Mobile Virtual Coach also leads on ads (none vs shown) and iOS requirement (15.0 vs 18.0). Caynax's advantage is update cadence (every 3 weeks vs every 3 months). On price and device support there is nothing between them.
