Watch Codex
Read full descriptionHide full description
View Codex usage on iPhone, Apple Watch and widgets. Check remaining limits, next reset times, extra usage balance and stored reset credits. Limit rings adapt to the five-hour or seven-day windows actually returned for the account, with segmented rings for the hours or days remaining. Sign in on iPhone and fetch usage directly without a Mac or server. While open, the app refreshes about every 30 seconds. In the background it requests an update no earlier than 15 minutes later, then syncs a successful update to widgets and the watch. iOS chooses the actual background time based on power, network and usage, so real-time updates are not guaranteed. Supports Chinese, English, Japanese and Korean. Requires an OpenAI account with Codex access and an internet connection. Available fields depend on the account and service. The app does not redeem resets or purchase credits. It is an independent utility, not affiliated with or endorsed by OpenAI. Add circular, corner, rectangular or inline Apple Watch complications to see remaining usage on a compatible watch face. The iPhone app, widgets, Apple Watch app and watch-face complications are available without an in-app purchase. The free iPhone app shows fixed top banner ads. One optional non-consumable purchase only removes iPhone ads; it does not unlock features or third-party content. No subscription. Allow notifications for alerts when a successful refresh detects that the primary quota has crossed 10% or 3%, or fully reset. Events are forwarded to your paired Watch. Delivery timing, sounds and haptics follow system scheduling and settings.

Keep an eye on your AI agents, even when you step away from your Mac. Agent HUD brings the usage, quotas and session activity collected on your Macs to your iPhone and Apple Watch. Check what is running, see how much quota remains and explore where your tokens go. QUOTAS AND BALANCES View available Claude, Codex, Antigravity, Cursor and Grok quotas and reset times, Codex usage resets, and DeepSeek balances and estimated costs. Available readings depend on the tools and accounts connected on your Mac. TOKEN USAGE Explore usage over 5 hours, 24 hours or 7 days. Compare models, choose input, output and cache-read tokens, and inspect charts and activity patterns. SESSIONS AND MACS Browse synced session summaries, models, token totals and recent activity. Read recent conversations shared by your Mac from Claude Code, Codex, Grok CLI, Grok Bot and Antigravity. Explore Codex subagent tasks and separate conversations from their parent conversation. View all your Macs together or focus on one device. LOCAL NETWORK CONNECTION Turn on local network sharing on your Mac, then scan its QR code with your iPhone to view that Macโs data directly on the same local network. QR pairing does not require an Agent HUD Remote subscription. WIDGETS AND APPLE WATCH Put quotas, balances or token charts on your Home Screen and add Lock Screen widgets. The Apple Watch companion shows quota rings, usage charts and recent sessions. LIVE ACTIVITIES AND NOTIFICATIONS Follow running sessions on the Lock Screen and Dynamic Island on supported iPhones. Receive turn-completion and quota or balance alerts. Automatic Live Activities require iOS 18 or later; Live Activities in the paired Apple Watch Smart Stack also require watchOS 11 or later. IPHONE DUO On the inner display in landscape, Home and Stats use two columns, and Sessions shows the list beside the selected session. Fold the phone to continue with the same session on the outer display. REQUIREMENTS Agent HUD for iPhone and Apple Watch is free to download. The new local network and conversation features require Agent HUD Mac version 0.4.39 or later. To sync data away from your local network, enable Agent HUD Remote on your Mac. You can subscribe to Agent HUD Remote in the app through the App Store: plans cover 1, 2 or 3 Macs, monthly or yearly, and the first week is free. iPhone and Apple Watch do not count toward the Mac limit. Terms of Use: https://www.apple.com/legal/internet-services/itunes/dev/stdeula/ For remote sync, sign in to the same Apple Account in system settings on your Mac and iPhone. Apple Watch requires a paired iPhone with Agent HUD installed. Requires macOS 14, iOS 17 and watchOS 10 or later for the respective apps. Displayed information depends on data collected and synced by your Mac. Background updates, notifications, widgets and Live Activities are scheduled by Apple and are not guaranteed to update immediately. Agent HUD does not provide AI model access or run coding tasks on your phone.

Verdict
The clearest difference is in-app purchases: Agent HUD at none against Watch Codex's 1. Agent HUD also leads on ads (none vs shown). On price, update cadence, device support and iOS requirement there is nothing between them.
