Your day: 9 a.m. in the chair, 6 p.m. still in the chair. Shoulders tight, eyes dry, and that glass of water on your desk โ untouched since morning. WorkZen is the desk-health companion that actually looks after you, so you don't have to remember: STAND UP โ gentle reminders to get up and move, tuned to your work rhythm. Manual or auto. DRINK WATER โ log your daily intake with one tap. Reminders when you've forgotten your glass. REST YOUR EYES โ 20-20-20, blinking, and guided eye breaks for screen-heavy days. STRETCH โ short desk routines for tight necks, shoulders and backs, with step-by-step voice guidance. NAP โ a smart break timer that wakes you refreshed, not groggy. Want more than a timer? WorkZen's wellness clock walks you through the body's natural two-hour energy cycles โ an ancient system for better sleep, focus and digestion, explained with modern science, not mysticism.

Verdict
The clearest difference is in-app purchases: HIIT Trainer at none against WorkZen's 1. HIIT Trainer also leads on update cadence (every 2 days vs fortnightly). WorkZen's advantage is iOS requirement (14.0 vs 16.0). On price, ads and device support there is nothing between them.
