Beyond the Guidebook: The Definitive Rock Climbing Resource. • Find outdoor climbing areas near you, and navigate to them, using the map. This super-handy new feature is one of our personal faves. • The much requested route finder: Easily sort routes by discipline, difficulty, star ranking and more. If a 4-star M9 is your thing, we'll help you find it. • Search our entire database of 155,000+ climbing routes, even offline. • Download route beta, photos, and topos state by state for offline use — because the best crags often have the worst reception. • View a climbing area’s route stats (how many 5.11s are there?) and critical info (when is the raptor closure again?) in a single glance. • Chat, ask questions, or put out a call for partners in our forum. • Rate routes and photos, keep track of attempts & sends, or make a to-do list • It's free to download and free of advertising too.

Verdict
The clearest difference is review sentiment: NYC Flash at 100% against Mountain Project's 41%. NYC Flash also leads on rating (5.0 vs 4.6) and update cadence (weekly vs every 3 weeks). Mountain Project's advantage is ratings volume (4.6K vs 12). On price, ads, in-app purchases and monetization model there is nothing between them.
