Usage Halo

Usage Halo puts your AI usage limits in one glanceable ring, in the Dynamic Island, on the Lock Screen and in widgets, so you know how much is left before you hit the wall. CONNECT YOUR ACCOUNTS Sign in to the services you already pay for: • Claude: your 5-hour session and weekly limits • OpenAI (Codex with ChatGPT): your 5-hour and weekly limits • GitHub Copilot: your monthly premium-request and chat quotas ONE RING, YOUR CHOICE Show one or two providers on the ring. With two, the ring splits in half; with one, it takes the whole circle. The outer ring is the longer window and the inner ring is the shorter one. You decide which providers appear, and whether the percentage beside the ring shows the 5-hour or the weekly window. EVERYWHERE YOU LOOK • Dynamic Island: a compact ring and the tightest limit, expanding to every limit and its reset time • Live Activity on the Lock Screen • Lock Screen and Home Screen widgets • Control Center control (iOS 18) to bring the ring back without opening the app STAY AHEAD OF YOUR LIMITS • See how much is left as you get close to a limit • A live countdown to the reset once you hit it • A dot when a free OpenAI reset is waiting for you • A brief alert at 85% and 100% PRIVATE BY DESIGN • Sign-in happens with each provider; Usage Halo never sees your password • Tokens stay in your iPhone's Keychain and go only to the provider they belong to • No server, no analytics, no ads, no tracking • Delete everything with one tap in Settings Usage Halo is free, with no in-app purchases and no ads. To see your own limits you need an existing subscription with at least one supported service. You can try the app with sample data first. Usage Halo is an independent app and is not affiliated with, endorsed by or sponsored by Anthropic, OpenAI or GitHub. It reads usage information that each provider's own tools make available; providers may change this at any time, which can affect what the app can show.
