I really want to love this app. Honestly, I do. But the UI/UX is bad. There's no clear way of finding what you're looking for, no clear direction on where I should go. It's just confusing.
App is inaccurate

I go to temescal gateway park frequently, at least for this park this app is terrible. It doesn’t show that temescal canyon and temescal ridge trails connect. It’s a popular route. There’s a scenic point with no trail nearby on the app. It also misled me further up the canyon.
Not for bicycling

For bicycle trails, it shows only connectors and accesses. You cannot see an entire trail. e.g, the San Gabriel River Trail runs from Seal Beach To up behind the Santa Fe dam. You’ll not find it. Same with Rio Hondo, LA River, etc. The only one I see is Ballona Creek.
Developer Response
Sorry to hear the app isn't working well for you, re: bicycling. All the data in the app comes directly from Los Angeles County, but there may be missing context (trails, points of interest, etc.) for areas that fall outside their jurisdiction.
Photo challenges open reliably, pulling to refresh in Explore no longer freezes the app, and organization screens open offline after you've visited them. Photo galleries show larger photos, maps frame parks more accurately, and a stalled offline download ends with a retry option.
