Helm

什么是 Helm？

Helm is a free, browser-based tool for designing mobile app journeysscreen by screen, flow by flow. No login, no install. It's the first design tool built bilingual from the ground up: every journey works in English and Arabic with proper RTL, and it speaks banking natively (conventional ↔ Islamic finance terminology). Built-in flow audit scores your journey's readiness, and the Developer Handoff Pack exports a spec devs can actually build from. Useful for anyone designing an app flow.
