### 1/5 — Come buttare via soldi

*2024-09-29, version 7.5*

Se no sapete come buttare via soldi questo è il momento giusto.

### 5/5 — Fine and Enough!

*2023-05-18*

Everything is fine, just please don't stop supporting and provide updates. Thank

### 5/5 — Works great especially in the field

*2022-10-16*

Great

### 2/5 — How to edit?

*2018-10-11*

I see no way to edit a site once the coordinates are entered. That means i have to start the entire site coordinates for both ends over again?

I tried to use the App Support link and there is no way to contact the developer. This stinks

**Developer response:** Hi, in the app.. there is the "Contact" button - the button opens a new email to "cristynodev@gmail.com".
You could contact us for new improvements - we were expecting them with pleasure.
Thank you!

### 4/5 — Excellent app

*2017-08-23, version 4.0*

👍

### 5/5 — Fantastic app

*2017-06-10, version 4.0*

Used for various frequencies path calculations and performs really accurately. Give good estimations at both vhf and uhf. 

Highly recommended for 144, 432 and 446 use.

Super fast developer support

### 1/5 — Program covers 30 MHz and above

*2017-01-04*

Purchased this program coverage 7mhz to 30 MHz.  No where on the snap view is this stated. Suckered in and no way to get a refund.  Vendor should be removed for incomplete information.

**Developer response:** Please, read again the description: "The RF Haversine analysis covers the range of 35MHz- 48GHz" - it's written from 2013

### 5/5 — Best app in my toolkit

*2016-04-16*

Wow... Don't tell the developers, but I would have paid three times as much for this. It's a fantastic tool for any outdoor RF engineer, and I can't wait to see what they do next.

### 1/5 — Does not work

*2015-12-04, version 3.1*

This appears to be incomplete. Save your money.

### 5/5 — makes calculations easy & quick

*2015-11-08*

Worth every penny.  Turns what used to be a complicated and time consuming activity into speedy fun.  Especially good for playing “what ifs” to manipulate variables and see their effect.
