Notice the signal. Stay at the surface. Skin Alert is a minimal timing utility designed to help you acknowledge surface-level alert moments in a calm, distraction-free environment. Instead of guidance, interpretation, or urgency, Skin Alert focuses on clear time awareness and a restrained visual atmosphere where each signal feels intentional and contained. – Trigger surface alert sessions with simple start / stop timing – Experience subtle surface-inspired visuals with slow, controlled motion – Use Surface Mode for label-free, ambient alert moments – View a minimal history of recent alert sessions – Adjust surface motion intensity to match your comfort – Optional local reminders with neutral wording – Fully offline: all data stays on your device – Designed with a clean red, white, and black surface aesthetic Skin Alert is not about diagnosis or advice — it's about awareness, attention, and clear moments at the surface. Notice. Pause. Acknowledge the signal with Skin Alert: Surface.

Verdict
The clearest difference is in-app purchases: Skin Alert at none against Zertú's 10. Skin Alert also leads on update cadence (every 9 days vs every 5 weeks). On price, ads, device support and iOS requirement there is nothing between them.
