Tired of generic calorie counters that don't understand your weekly rhythm? Welcome to Sycle, the smart health companion designed specifically to sync with your medication half-life and weekly body cycles. Weight loss injections don't work linearly—they operate on a weekly peak and trough cycle. Sycle synchronizes your daily nutrition, hydration, and side-effect management with your exact medication status. KEY FEATURES: • DYNAMIC HALF-LIFE CURVE Visualize your medication levels in real-time. Know exactly when you’re in Peak Phase (high nausea risk) versus Trough Phase (appetite rebound risk). • CYCLE-AWARE NUTRITION TARGETS No more rigid daily calorie goals! Sycle automatically adapts your targets based on your cycle: - Peak Days (Days 1–3): Focus on liquid protein and hydration to ease nausea. - Trough Days (Days 5–7): Focus on fiber and satiety to prevent bingeing. • LEAN MUSCLE MASS PROTECTION Losing weight shouldn't mean losing muscle. Sycle calculates dynamic protein safety floors to keep your metabolic engine strong and prevent muscle loss. • SIDE EFFECT RELIEF & TRACKING Log nausea, constipation, acid reflux, and fatigue. Discover which foods aggravate or ease your symptoms during specific cycle phases. • ZERO-FRICTION MEAL & MACRO LOGGING Designed to eliminate "calorie anxiety." Log meals in seconds with intuitive portion taps, tailored specifically for low-appetite days. 100% On-Device & Private: Your health & medication data NEVER leaves your phone. No accounts, no cloud servers, no data selling. Zero-Server Architecture | 100% Local Privacy Take control of your health journey today with smart, cycle-based science. Disclaimer: Sycle is a health management and tracking tool and does not provide medical advice, diagnosis, or treatment.

Blink Analysis is an informational tool that measures blink dynamics using your iPhone’s front camera. After completing a short standardized blinking test involving four visual tasks, you can view measurements such as blink rate, eyelid closure, blink duration, closing and opening intervals, velocity, symmetry, and interblink interval. Blink Analysis uses high-frame-rate video and facial landmark tracking to analyze these recordings directly on your device. Your test recordings and results are stored locally on your device. Blink Analysis does not automatically upload your videos or measurements to the developer or to an external server. You can export session files yourself or delete all locally stored session data from within the app. Blink Analysis is intended for informational and educational use only; its measurements have not been validated as clinical diagnostic tests, and the app does not diagnose or rule out any medical condition.

Verdict
The clearest difference is update cadence: Blink Analysis at every 5 days against Sycle's monthly. Blink Analysis also leads on device support (3 vs 1). On price, ads, in-app purchases and iOS requirement there is nothing between them.
