Last updated: June 2026. This comparison is audited regularly for feature and pricing accuracy — every claim about Appointment Scanner below is sourced from appointmentscanner.com.
You got Conditional Approval for Global Entry. You checked the CBP portal. The nearest interview is six months out. So you started Googling, and two names kept coming up: Appt Helper and Appointment Scanner.
Both services do the same core thing — they watch the CBP enrollment calendar and text you the moment a cancellation slot appears. But there are real differences in how they handle urgency, how many locations they cover, and what you actually get for the price. If you're at a high-traffic airport like JFK or LAX, those differences can determine whether you catch a slot or miss it.
Here's the straight comparison.
What Does Each Service Actually Do?
When someone cancels a scheduled Global Entry interview, that slot shows up on the CBP portal — typically for seconds before another applicant grabs it. Refreshing the page yourself doesn't cut it. The window is too short.
Both Appt Helper and Appointment Scanner automate that monitoring. Their software checks the CBP scheduling system on a regular cadence and fires an alert the instant a slot appears. You click the link, log into the TTP portal, and book it before it's gone.
The gap between them comes down to how fast that alert reaches you, and through how many channels.
Urgency: The Most Important Variable
At a location like SFO or ORD, a cancellation can disappear in under 10 seconds. The gap between getting your alert immediately versus getting it a minute later is the gap between booking your interview and watching someone else take it.
Appt Helper Priority is built for that scenario. When a slot opens, it fires SMS, email, and browser notification simultaneously — so you're covered whether you're at your desk, away from your phone, or have your ringer off.
Appt Helper Standard is the smarter choice if you're not in a race against the clock. Maybe your location isn't perpetually slammed, or your schedule gives you flexibility. Same multi-channel alerts, same 3-location coverage, at $19.99 instead of $34.99.
Appointment Scanner is a well-established service and it's worked for a lot of people — they're featured in Forbes, CNN, and The Points Guy, and back their service with a 30-day money-back guarantee. Their scan frequency isn't publicly disclosed, so we can't make a verified speed comparison either way. Appt Helper targets a 3–5 minute scan interval, which we can state because it's our own infrastructure.

Pricing: One-Time vs. Monthly
This is the actual differentiator, and it's easy to miss if you're just comparing sticker prices.
Appt Helper Standard runs $19.99 and Priority runs $34.99 — both are single, one-time payments that keep monitoring until you book (up to 60 days, backed by a money-back guarantee for that whole window). Appointment Scanner charges $29 for one month of service; if you haven't booked by the end of that month, you'd need to pay again to keep monitoring.
If you book within the first month either way, Appt Helper Standard is the cheaper option ($19.99 vs. $29) for the same coverage. If it takes longer than a month, the gap widens — Appt Helper's guarantee window covers that time at no extra charge.
Multi-Location Monitoring
Both services cover up to 3 enrollment centers, so this isn't actually a differentiator between them — it's worth mentioning only because some competitors in this space cap you at a single location, and these two don't. If you're in the Bay Area, you can run SFO, OAK, and SJC at the same time with either service. Whoever cancels first, you're there.
Which Service Should You Use?
If you need to move fast — particularly if you're monitoring JFK, LAX, SFO, ORD, or another high-traffic airport — Priority at $34.99 is the right call. It's designed specifically for those situations where a slot appears and is gone before most people even see the notification.
If you have some breathing room on timing, or your location tends to have steadier availability, Standard at $19.99 is solid coverage at a fair price.
Appointment Scanner is a proven service with a real track record. If you're already set up and getting alerts there, there's no compelling reason to switch mid-hunt. But if you're choosing for the first time: the two services are equivalent on location coverage and alert channels, so it comes down to pricing structure and urgency tier. Appt Helper's one-time payment (vs. Appointment Scanner's monthly $29) is the better deal if your search takes longer than a month, and the Priority tier is the one option built specifically for high-demand airports.
The Bottom Line
The CBP interview backlog is real and it's not getting better on its own. Both services attack the same problem: watch the cancellations, alert you instantly, you book the slot. Both cover up to 3 enrollment centers with SMS and email alerts.
What separates Appt Helper is the one-time pricing (no repurchasing if your search runs past a month), the 60-day guarantee, and the Priority tier built specifically for high-demand airports. If speed matters to you, set up monitoring for every enrollment center within reasonable distance of where you live.
