native

Straight to the GPU.
Nothing in between.

higherMark is built on GPUI — the pure Rust engine behind the Zed editor, written for 120 FPS desktop apps. No webview. No DOM. No JavaScript bridge. No garbage collector. Every rectangle, shadow and glyph is drawn by custom GPU shaders, so the CPU stays free and the interface never stutters.

iOS ships Swift native over a Rust core via Tauri. macOS runs GPUI on the same Rust engine.
up to 8× faster to launch · up to 16× lighter in memory
Reference figures from Zed (GPUI) measured against Electron editors on Apple Silicon. GPUI ships its own GPU renderer rather than borrowing the system webview, so the bundle sits above Swift and Tauri — and still a fraction of Electron, which carries an entire Chromium.

lightning speed.

Cerebras is the default because nothing on earth is faster. Its wafer‑scale engine returns ~3,000 tokens per second — where the rest of the industry lands between 50 and 200. That's not a spec‑sheet win. It's the difference between waiting on an answer and simply having one, fast enough for the pace of your day.

Switch to 300+ models across providers, or run on‑device, on the fly.

the pool

Pool the power.

Everyone's compute, one grid. A difficulty adjustment allots by contribution. Desktops carry more, phones ride along and pay less for more, faster. Always on auto, wherever you are. Online or not.

offline

No bars.
Still pays.

Tap a Square terminal at the food court with zero service and zero wifi. Send, spend, scan, and keep asking questions. It all works offline. Scan any Square terminal or any terminal that supports lightning too.

Already everywhere
you are.

Lightning isn't waiting to arrive — it shipped. Square put it in millions of merchant terminals and Cash App runs it for tens of millions of people, a bigger footprint than most banks. higherMark speaks the same language, so money moves in about a second — any hour, any day, with no percentage taken off the top.
