Tripadvisor: Plan & Book Trips — Revenue & Downloads Estimate

Appdex shows coarse buckets for small apps — under $5k/month here — and keeps the exact confidence band inside the product. Bigger apps get the full honest range right on this page.

Behind this number is an engine that never stops: it re-processes millions of rows of App Store signals every day across 1M+ apps, rebuilds every estimate nightly, and grades its own accuracy against tens of thousands of independently known figures before anything ships.
