## Most critical reviews (10 lowest-rated)

### 1/5 — Coordinate converter

*2024-10-04*

Unfortunately it won’t allow more devices as it’s supposed to, no support whatsoever.

### 1/5 — Not accurate

*2018-10-09, version 2.0*

Converting MGRS to Lat/Long DM is way off

### 4/5 — Works As Advertised

*2025-08-07*

Does exactaly weekday I need it to do.  Simply convert coordinates. 

I would love to see a tab function and or not have to delete all the zeros.

Lastly I couldn't send a review to the author via the app.

### 4/5 — Awesome App

*2017-11-30*

Great to have it working again.
I like the accuracy of the position and detail of the satellite maps. This gets used all the time at work.

### 4/5 — Great app!

*2015-03-13*

Perfect for SAR folks who need to quickly find positions or convert coordinates in multiple formats, without having to switch formats in your GPS.

The one glaring omission is the inability to switch datums. Add that functionality, and maybe some minor UI tweaks, and it's a five-star app! :-)

### 4/5 — Enhancement requests

*2013-04-14*

Sean, please have this app use Google Maps; it's simply much better. Also, after the user inputs coordinates, let the user then press the Map button and have Google Maps (or whatever map app) open with it already zoomed in and with a pin showing the location of the entered coordinates. I really need this!

### 5/5 — Great app!!

*2022-01-02*

I use the utm data to locate marked future water well  locations. A great big help. Thanks

### 5/5 — Coordinate converter

*2021-07-01*

Brilliant app, only bug bear is it doesn’t sync with other devices

### 5/5 — Very handy app

*2014-01-16*

This app is quick, precise, and helpful when converting different GPS coordinates. It also has a share feature for messaging your input to others

### 5/5 — Less is more

*2012-10-13, version 1.1*

For my search and rescue application this is great. Simple data input gives me conversions to the other formats quickly and easily. I can see the location on a map and send the conversion to others.
