User Reviews

Topo Reader is generally praised for reliability and usefulness, a simple interface, and free access to historical USGS topo maps with a robust feature set. However, multiple reviews point to disruptive in-app ads in the free version, which can hinder map viewing, and some users report issues with premium access. Overall, it’s valued for maps and planning, with ads reducing the free experience.

Pros

Reliability and usefulness for mapping and trip planning
Simple, well-designed interface with good help/documentation
Free access to historical USGS topo maps and a robust feature set
Good value with an affordable lifetime license

Cons

Ads in the free version frequently disrupt map viewing (full-screen interruptions)

Recent reviews

Overall a good app. However, it randomly zooms out. It would also be nice to be able to lock the nav modes, which change every time the screen is touched. Map uploading is easy, but have difficulty keeping them on top.

Living in a remote rural area of the West, surrounded in every direction by public land, iPhone mapping and navigation apps are very useful. Topo Reader is the 5th such App that I have tried and used over a number of years. I find myself using it more than any other. Where others with more layers and features have inexplicably failed, it has functioned flawlessly. The beauty of this App is its simplicity. I signed up for lifetime use and that cost was a fraction of the $60-100 a year that some Apps are pushing now.
