Every detail considered
Three-Screen Rotation
Price, Stats, and Mood Market screens rotate automatically — showing you price, 7/30-day trends, and sentiment data in sequence.
8 Alert Tiers
From Small Gain to Double Rainbow, every price movement triggers a matching LED effect and audio cue so you never miss a move.
Night Mode
Set a quiet window. During night hours LEDs dim, audio mutes, and an optional Night Signature theme takes over the display.
Mood Market
Card Mood, Market Volatility, 30-day Sentiment — all distilled into human-readable labels like 'On a heater' and 'Bull run'.
Custom Audio

WiFi Setup Portal

Never miss a move
8 Alert Tiers
Every threshold is user-configurable. Each tier fires a unique LED effect and one of three random audio cues simultaneously.
Small Move
Gentle green or red breathing LED. Subtle enough for a desk without disrupting your work.
Big Move
Orange-red climbing animation for gains. Blue fire for losses. Something's heating up.
Medium Move
Alternating green/gold flashes for gains. Red/blue police flash for losses. Hard to miss.
Huge Move
Full spectrum sweep for a massive gain. Red drips stacking Tetris-style for a crash.
Small Gain · Small Loss · Big Gain · Big Loss · Medium Gain · Medium Loss · Huge Gain · Huge Loss — all configurable in the setup portal.
