Someone else waits. You show up. Every great thing in New York has a line in front of it. The restaurant that doesn't take reservations. The sneaker drop. The sample sale your coworker "just happened" to catch. Every StandIn is personally screened by the founder. How it works: • Browse this week's real NYC lines, or request one you want covered. • Pick your time window and see the price before you book. • Updates appear in your booking as your StandIn moves up the line, and you get a push alert when it's time to head over. • When your spot's near the front, you get the word. Walk up, swap in, done. You only pay once a StandIn has accepted your requestStandIns are real New Yorkers: met in person, ID-checked, and trial-shifted before they ever hold a spot. We never cut. One person out, one person in, well before the front. Venues barely notice us, and that's the point. Currently a limited NYC pilot. A real person reviews every request, and we only confirm what we can actually cover.

Verdict
The clearest difference is in-app purchases: StandIn at none against Millisecond Clock's 3. StandIn also leads on ads (none vs shown) and update cadence (every 10 days vs every 6 months). Millisecond Clock's advantage is iOS requirement (15.0 vs 18.0). On price and device support there is nothing between them.
