If you've reached Conditional Approval for Global Entry and discovered that the nearest interview isn't available for six months, you've probably searched for a monitoring service to help. Two names come up constantly: Appt Helper and Appointment Scanner.
Both do the same fundamental job — they watch the CBP Trusted Traveler enrollment calendar and notify you when a cancellation opens up. But the details of how fast they alert you, how much they cost, and how many locations they cover can make a real difference in how quickly you actually get your interview done.
Here's the direct comparison.
What Does Each Service Actually Do?
When someone cancels a scheduled Global Entry interview, that appointment slot becomes available on the CBP portal — usually for only a matter of seconds before it's claimed by another applicant. Manually refreshing the portal yourself is ineffective; by the time you spot the opening, it's gone.
Both Appt Helper and Appointment Scanner solve this by automating the monitoring process. Their software polls the CBP scheduling system regularly and fires off an alert via SMS or email the instant a slot appears. You click the link, log into the TTP portal, and book the appointment.
The question is which service gives you a meaningful edge.
Speed: The Most Important Variable
The entire value of a monitoring service comes down to one thing: how fast does it detect an opening and how fast does it notify you?
Appt Helper Priority checks the CBP portal for urgent cases. That's the fastest commercially available monitoring interval we're aware of. When an appointment opens, an SMS, email, and browser notification are sent immediately.
Appt Helper Standard uses a standard monitoring interval — a solid choice if you're monitoring a high-volume enrollment center (like JFK or LAX) where openings appear more frequently throughout the day.
Appointment Scanner is a well-established service in this space. Based on publicly available information, their monitoring runs at intervals that are typically slower than Appt Helper's Priority Premium cadence.
For high-demand locations where openings vanish within seconds, that gap matters. If you're monitoring a quieter location, both services will generally perform similarly.

Pricing: Both Are One-Time Payments
Both services charge a one-time fee — no subscription, no recurring billing.
Appt Helper Standard is $19.99 (up to 3 locations) and Appt Helper Priority is $34.99 (up to 3 locations with Priority monitoring). Both monitor for up to 60 days or until you book. Appointment Scanner is similarly priced as a one-time purchase.
Since pricing is comparable across both services, the decision comes down to monitoring speed and multi-location coverage — both of which favor Appt Helper.
Multi-Location Monitoring
One of the more overlooked features is the ability to monitor multiple enrollment centers at once. If you live between two airports, or if your home location is particularly backlogged, watching several sites simultaneously dramatically increases your chances of landing a fast appointment.
Both Appt Helper plans monitor up to 3 locations simultaneously — Standard at $19.99 and Premium at $34.99. This is a significant advantage over services that only monitor a single location per plan.
If your home enrollment center is SFO, for example, you can also simultaneously watch OAK and SJC. Whoever cancels first, you're there.
Which Service Should You Use?
For the fastest possible alert speed: Appt Helper Priority is the clear choice at $34.99 one-time — Priority monitoring across up to three locations for up to 60 days.
For solid multi-location coverage at the lowest price: Appt Helper Standard at $19.99 one-time monitors up to 3 locations at a standard interval — and undercuts most competitors on price.
Appointment Scanner is a legitimate, well-known service that has helped many people. If you've already signed up and it's working for you, there's no urgent reason to switch. But if you're choosing for the first time, the combination of Priority monitoring speed, one-time pricing, and multi-location coverage gives Appt Helper a meaningful edge for most use cases.
The Bottom Line
Both services exist to solve the same frustrating problem: the CBP interview calendar is backed up for months, and the only practical workaround is watching for cancellations. Both charge a one-time fee. Appt Helper's edge is its Priority monitoring speed and the ability to watch up to three locations simultaneously — two factors that meaningfully increase your chances of landing a fast appointment.
If you're Conditionally Approved and want to get your interview scheduled as fast as possible, start monitoring with Appt Helper and set up alerts for every enrollment center within a reasonable distance.
