Zero vs STARK

Mission Log & Calendar – review your completed missions, track missed days, and celebrate personal records. Smart Notifications – daily reminders and community event alerts keep you engaged. How a day works Briefing – the Mothership reports today’s crisis. Pre-brief context – why the mission matters and what you’ll do. Mission – e.g. Hydraulic Squats (15 reps, 40s).
