AI Session Meter

Most tools just show you a number. AI Session Meter also reads your pace and predicts whether — at your current rate — you'll use up your session or weekly limit before it resets. Slow down, switch models, or wrap up the task: you can make that call before you're locked out mid-work.

Now on iPhone, iPad, and Apple Watch — one purchase, every device
• Weekly limit cards for every account: % used, % remaining, and time until reset at a glance
• A Daily view showing each account's current session usage
• Hourly Daily/Weekly graphs with reset markers — see exactly when a limit reset
• Home Screen widgets (Weekly / Daily) and an Apple Watch complication
• Your usage history syncs automatically from your Mac through your own iCloud — no account or sign-up required
• Requires AI Session Meter on your Mac: the Mac app reads and records your usage — iPhone, iPad, and Apple Watch display the data it syncs

The headline feature — pace warnings
• Projects how much you'll use by the next reset, based on your current pace
• Alerts you in the menu bar the moment you're trending toward running out
• Warnings can also pop up on your iPhone and Apple Watch, delivered through your own iCloud
• Keeps you from being suddenly locked out in the middle of your work

Stats — understand how you actually work
• A GitHub-style activity heatmap of your coding history
• Tokens per day by model, with 24-hour, 7-day, and 30-day views down to hourly detail
• Hover any chart or heatmap cell on the Mac for instant date, time, and token counts
• Built from your local Claude Code session logs; view them on your Mac or synced to iPhone and iPad

How AI Session Meter gets its data — and what it never does
• AI Session Meter never calls any AI model. It does not use Claude, Codex, or any other inference API, and it never consumes your usage quota.
• Claude Code usage (Mac): read with the access token you enter, directly from Anthropic's official usage API. Your token is stored only on your Mac, and Anthropic is the only place it is ever sent.
• Codex usage (Mac): OpenAI offers no public usage API, so AI Session Meter reads the rate-limit snapshots the Codex CLI itself writes to your local ~/.codex folder. The numbers update only when Codex actually runs, and nothing is ever sent off your Mac.
• iPhone, iPad, and Apple Watch never connect to any AI service. They display the history your Mac recorded, delivered through your iCloud.

Also shows
• 5-hour session usage and reset time
• Weekly all-models usage and reset time
• Multiple accounts at once, under the names you give them
• Sortable account cards — by usage, by name, or your own drag-to-arrange order

Designed for each platform
• macOS: lives in the menu bar; auto-refreshing, universal for Apple Silicon and Intel, barely any memory or CPU
• iOS / iPadOS: a dashboard and widgets, pleen awake while charging
• watchOS: glanceable usage on your wrist, a watch-face complication, and mirrored alerts

Built with privacy in mind
• Fully sandboxed; no analytics, tracking,
• Your access token is stored only locally on your Mac; usage requests go only to Anthropic's official servers
• Codex data and Claude Code logs are read you grant access to
• Device sync and alerts use only your own iCloud account — there is no developer server
