## Most critical reviews (10 lowest-rated)

### 1/5 — Premium isn’t permanent

*2020-09-21, version 7.2*

I paid for premium, and now I can’t use it anymore!!!

### 1/5 — CRASH

*2015-08-24*

Sorry guys, but this app looks promising but keeps crashing on latest iOS iphone 6.

### 1/5 — Ads make it unusable even to try

*2015-05-12, version 2.1*

This seemed like an amazing app at first. I thought for sure I'd look into the paid version once I'd reached my maximum # of maps. But I couldn't even download the 3 maps I needed to look at the trails I'm hoping to walk on, because every time I scroll to find the map location, a 15 second ad starts playing. The app is unusable as a trial. It seems to have high potential, but I'll have to look at other apps instead since the ads in this one make it impossible to view the maps (which are available free on USGS website.)

### 1/5 — Impossible to Use Due To Advertisements

*2015-03-30, version 1.1*

When the "in-app advertisements" suddenly pop up, they take up the entire screen.  This happens so frequently, it makes the app pretty much useless for its intended purpose.  I'm okay with ads in "free" versions of applications, but this near-constant full-screen takeover defeats the purpose of a mapping application.

### 1/5 — Бесполезная

*2014-12-23, version 1.1*

Обычный просмотрщик карт! Никаких Топокарт нет

### 3/5 — Basique

*2026-03-21*

Peu d’outils mais fonctionne bien pour une navigation simple.

### 3/5 — Random zooming

*2025-11-08, version 8.1*

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.

### 4/5 — Good app and cheap!

*2017-06-28, version 5.2*

Seams to work well. Recommend the 3 month option.

### 5/5 — Topo Reader is my 5th iPhone Mapping App

*2025-08-09, version 8.1*

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.

### 5/5 — Real estate

*2019-12-17, version 7.2*

Great

Very useful!

### 5/5 — Great

*2019-04-23, version 7.2*

view Maps Old and New

### 5/5 — A brilliant topo app!!!

*2015-06-08, version 2.1*

This is a marvelous free topo-map reader that's chocked full of powerful special features not found in many similar but expensive paid apps. The interface is brilliantly designed for maximum control and flexibility, and the extensive integrated help file makes this app a joy to use. The developers are to be congratulated for providing the public with free access to historical USGS topo maps through such a logical, powerful, and appealing tool. This topo reader has quickly become indispensable to me in planning hiking and climbing trips. I absolutely LOVE this app and would give it 10 stars if I could. ⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️

### 5/5 — BEST APP EVER!!!

*2015-01-26, version 1.1*

This is the greatest app. Used it too explore the my local mountain side. While I was looping the mountain side I found some suspicious wooden boards near the base of the mountain. Then I found an abandoned gold mine. I went in and found what appears to be gold flakes. I am planning to stay here quite a bit. Most people don't use these maps but I have found some maps that still have locations of old mines. After this exciting adventure I am heading to Nevada to look for silver mines. I would highly recommend this app.
