Live Chime Triggered: New Pro Plan ($49/mo)
Webhook synced from Stripe · confetti & chime broadcast to paired TV
architectural pillars
4K room glanceability & zero flicker
Televisions require fundamentally different UX than desktop dashboards: zero micro-interactions, massive contrast ratios, and complete immunity to burn-in or disruptive browser reloads. WallMRR delivers full 4K layout fidelity via native Apple TV (tvOS) and web displays, driven entirely by low-latency Server-Sent Events (SSE) that push live deltas without full-screen redraws.
deterministic minor-unit money arithmetic
Financial aggregation across multiple platforms is prone to floating-point drift and currency misalignments. The Go backend normalizes every stream into integer minor currency units (with dedicated support for zero-decimal JPY and 3-decimal KWD), reconciling mixed subscriptions across Stripe, Polar, and RevenueCat with zero double-counting.
ai agent mcp server & physical celebrations
Sales should be felt, not just filed. Webhook events immediately trigger synchronized audio chimes and visual celebration bursts. WallMRR also ships an RFC-compliant Model Context Protocol (MCP) server, empowering AI agents with revocable wm_mcp_ tokens to inspect MRR, post goal updates, or trigger celebrations directly on office TV walls.
