A free, mobile-first Old School RuneScape Grand Exchange tracker and OSRS flipping tool built for merchers who actually act on the data. Live insta-buy and insta-sell prices, target buy/sell anchored to recent fill probability, the 2% GE sales tax baked into every margin, a 5-day breakout scanner, a Bank-of-Gielinor portfolio tracker, and browser push notifications when your favorites break out.
No account. No login. No ads. Runs entirely in your browser; everything you save stays in your own device's storage.
Every other GE tool shows you the raw live margin or a simple historical average. PocketGE adds an execution layer:
- EV-based target prices — Target Buy / Target Sell aren't a percentile guess. They maximize expected captured margin =
P(offer fills) × (margin after 2% GE tax). P(fill) is built from a recency- and volume-weighted distribution of the actual recent tape. Too-low bids have fat margins but fill near-zero; too-high bids fill instantly but earn nothing. The product peaks at the realistic sweet spot. - 2% Grand Exchange sales tax built in (capped at 5,000,000 gp per item) so the displayed profit is what you actually keep, not a pre-tax illusion.
- 5-day breakout scanner — sidebar lists items currently testing their true 5-day high or low, built from rolling 1-hour volume-weighted candles. Bounded candidate pool so it never floods the OSRS Wiki API.
- Volume-split margin lists — High Vol Margins (100,000+ daily volume staples: gems, ores, bars, arrows, runes) vs. Low Vol Margins (slower-moving items with wider spreads), so you don't tie up capital in a slow item expecting a fast flip.
- Bank of Gielinor portfolio tracker with per-stack ±% PnL alerts.
- Notification Center with master toggle, test-fire button, and inline per-stack threshold editing — shows you exactly what alerts are armed.
- Mobile-first PWA — installable to your phone's home screen, service worker so it loads instantly, designed for tapping at a GE clerk rather than dragging a mouse.
