### 4/5 — Nice, but…

*2025-07-15*

…the font is not compatible with the iPhone 16 or latest iOS.  Otherwise cool app, the map is especially nice.  Please update app to adjustable font or smaller font.

### 5/5 — GMCMap Update Issue

*2025-03-21*

Reoccurring Issue: Update to version 1.0.4 does not upload data to map.  Also, every time I open the app, a message keeps appearing that states I need to update the app.  Yet, it was updated to the current version 1.0.4.  Adding the time stamp to the data was very helpful.  It would be helpful to have instructions for using the app.  Very promising app.  GQ GMC 600+ is great!

### 1/5 — Data not uploading to map

*2025-03-07*

Data not uploading to map in version 1.0.4

### 4/5 — Old and erroneous data

*2025-02-06*

Guys, you have reading on this map that are several years old or nonsense number that aren’t possible. If you want this map to be taken seriously you must clean it up. If the data is over a month old it should be removed. And there should be a way to report nonsense numbers.

### 5/5 — UFO/UAP

*2024-12-16*

Guys there are no nukes

### 1/5 — App doesn’t work

*2024-12-15*

I just downloaded GMCMap and it said I needed an update when I opened the app. I went back to the App Store and it’s up to date. Then it won’t load any map data saying there’s an issue with the server. Until I can get a working app I will leave this at 1 star.

### 1/5 — Cannot connect to server

*2024-12-15*

And thus the map is blank

### 5/5 — Pretty good app

*2023-09-24*

It serves its purpose with basic features, which is expected in an early stage. The dev is very active and very responsive to issues brought up in other reviews. 10/10

### 5/5 — This app changed my life

*2023-09-24*

Every day, I have woken up with a deep emptiness in my heart. For years and years I have carried on knowing something was missing: that is, until I downloaded GMCMap. Upon downloading this masterpiece of an application, I immediately knew I had found something special. I never knew how much the simple act of knowing radiation counts in my area would shatter my entire way of life as I knew it. GMCMap has taken up my entire day’s phone usage, and I’ve even began to uninstall other apps, since why would I need to go on anything but this wonderful app? I now wake up feeling whole, knowing both that my life is complete and also what CPM counts are nearby.
