The lineup

Two flavors

Two purpose-built apps — one tuned for crypto's clock, one for everything else. Each comes in two variants: a solo trading app, and a competitive group trader.

Crypto · on the clock

UP/DOWN

Purpose-built for Polymarket's rolling crypto up/down windows — BTC, ETH, SOL, XRP, DOGE, BNB & HYPE across 5-minute, 15-minute, hourly, 4-hour and daily markets. The instant one window settles the app rolls straight into the next, so you never stop trading. Behind every tap: a live price-vs-strike chart seeded from the oracle and Binance, real-time book pressure and order flow, a giant countdown, and honest CLOB odds.

Build your own board, then let each market bring its own live intel: pixel-art gamecasts that re-enact real plays, weather-model probabilities, Fed-release countdowns, and Kalshi fair-value twin lines — all drawn right on the chart.
