Experience the raw power and beauty of nature with this comprehensive self-guided driving tour through Yellowstone National Park!
Yellowstone:
This enormous volcanic caldera has captured the American imagination for decades, and you’re about to learn why. Full of awe-inspiring geysers, astonishing waterfalls, and some of the only wild bison and wolves on the continent, this park simply can’t be missed.
Marvel at the 200-foot eruptions from Old Faithful and the even bigger explosions of steam and boiling water from its cousins. Peer deep into the Abyss Pool (if you dare) and follow a boardwalk through steaming hot springs which never freeze, even in the dead of winter! And try not to let your jaw drop too low when you see Grand Prismatic, an immense hot spring which radiates brilliant colors.
Watch herds of bison graze in Lamar Valley and elk plod around Mammoth Hot Springs.…

No review analysis published for this app.
“Not assessed” means we could not measure it. It is never a zero and never a pass.
No package has been scanned for this app, so nothing is published about what it ships. That is an absence of evidence, not a finding.
Supporting measurements: not a complete list of possible harms or positives. Measurement vocabulary 1.4 · how these are measured
Not yet tested. No analysis has been run for this app, so there is no version or date to report.

yellowstone-audio-tour-guideWhat the stores publish. Store ratings are the stores’ numbers, not Appworthy’s, and are never averaged across stores.
From the store listing. Billing terms are read from each purchase’s name — the stores don’t publish them — so treat them as a strong hint, not a disclosure.
These are really on sale; we just can’t tell from the name whether they recur.
Not yet tested. No analysis has been published for this app, so there is no method to describe for it yet. A missing label is not a clean bill of health: it means nothing has been read, not that nothing is wrong.
Write to [email protected], or use the form. Name the finding, the app version and the evidence that needs correcting. Factual corrections are free and never depend on buying anything.
