## What is Watt CS?

Stop guessing. Start measuring.

Watt CS shows your charger's true output in real time — down to 0.1W — using direct hardware sensor data via the Nitro Library. Plug in and instantly know if you're getting fast charging, or being shortchanged by a cheap cable.

— REAL-TIME WATTAGE MONITOR —
• Live watts updated continuously with 0.1W precision
• Direct hardware sensor access via Nitro Library — not estimated
• Dynamic charging ring changes color and icon for Fast or Full states
• Professional hardware calibration ensures every reading is accurate

— BENCHMARK YOUR CHARGERS —
• Run scientific speed tests with custom start and end percentages
• Test Apple 20W, Anker, MacBook charger, or any cable side by side
• Charger Leaderboard automatically ranks every charger by real efficiency
• Know exactly which charger is worth keeping and which to replace

— SMART CHARGING HISTORY —
• Every session logged automatically: Max Watts, Avg Speed, Total Time
• One-tap filters: Fast, Normal, or Slow sessions in one tap
• Spot patterns — does your charger slow down at night? History reveals it

— UNDERSTAND YOUR BATTERY —
• 80% Trickle Detection with visual warning and science-backed explanation
• Know why charging intentionally slows after 80% to protect battery health
• No more wondering if something is wrong — the app explains it clearly

— PREMIUM & PRIVATE —
• No ads. No accounts. No internet connection required.
• All data stays entirely on your device
• Glassmorphism UI, full Dark Mode, animated splash screen
• Designed for iPhone and iPad

PERFECT FOR:
→ Testing a new charger before trusting it overnight
→ Diagnosing why your iPhone charges slowly
→ Verifying your cable actually supports fast charging
