Know your capacity. Know when it resets.

A Mac menu-bar app for remaining Claude and Codex usage, reset times, and whether you have enough to finish.

See how it works

The Phase Shift menu-bar popover. Claude has 41 percent left on its 7 day window and 68 percent on its 5 hour window; OpenAI Codex has 77 and 91 percent. Each row shows its reset time and a Continue normally recommendation. — Claude and Codex, together in one place.

Will you have enough to finish?

A percentage alone doesn't answer that. Phase Shift also considers your pace, planned work, and reset time.

20%left

Current capacity falls 75 minutes short of the reset.

Phase Shift recommendsConserve capacity

The popover reading Conserve capacity for OpenAI Codex, with 12 percent left on the 5 hour window resetting at 3:18 PM. — What a Conserve capacity verdict actually looks like in the app.

Run out of a 5-hour limit before noon?

Prime starts an eligible window earlier, so fresh capacity can arrive when the old capacity runs out.

Without Prime

2.5 hours interrupted

9:00 AM work starts 11:30 AM capacity gone 2:00 PM fresh window

Work stops at 11:30 AM and stays blocked until 2:00 PM.

With Prime

Work continues

6:30 AM Prime 9:00 AM work starts 11:30 AM fresh capacity

Fresh capacity arrives at 11:30 AM. The workday stays continuous.

Same limit. Better timing.

Prime doesn't add capacity. It only changes when an eligible window starts, so the next reset can land at a better time. It never runs without your say.

The popover recommending Prime at 6:12 PM for OpenAI Codex, currently at 12 percent with its window resetting 3:18 PM, showing now, prime at 6:12 PM, reset 11:12 PM, and a Use 1 Prime Ticket button. — What the app actually shows: the exact time to Prime, and the reset it would produce.

Phase Shift can suggest the timing, or you can choose it yourself.

Suggested

Phase Shift recommends when to Prime, when moving the window would better fit the work ahead.

Scheduled

Pick your own time instead. Phase Shift revalidates before it runs.

See the cutoff before it happens.

Before a build, refactor, or long AI session, see whether the capacity left can carry you through.

Plan client work around real capacity.

When Claude or Codex is part of the job, plan around both the time you work and the capacity you will have.

What's free, and what Pro adds.

Free

Monitor and plan.

Capacity, reset times, and recommendations for Claude and Codex. Always free, not a trial.

Complimentary Prime tickets

Try Prime twice.

Every install starts with two. Using one moves an eligible window's timing once.

Tickets are a Phase Shift allowance, not Claude or OpenAI credit or quota.

Pro

Unlimited Prime.

Includes supported Prime scheduling ahead of time.

An auto-renewing subscription, monthly or yearly, through the App Store. Apple shows the price before you buy, and handles renewal and cancellation in your Apple account.

The popover showing a Prime scheduled for 6:12 PM, with a note that Phase Shift will revalidate before execution, and a Cancel button.

A Mac utility, not another dashboard.

Phase Shift lives in your menu bar and reads the Claude and Codex accounts you connect.

No Phase Shift server. No team tracking. No extra Phase Shift account.

Connect Claude from the popover.

The first-launch connection screen offering Connect Claude and Connect Codex, with a Continue button and 2 Prime Tickets shown in the header. — One connected provider is enough to start.

Put your capacity where your day needs it.

See what you have, know when it's back, and shift the timing when that helps.
