## What is APRS TX?

APRS TX allows licensed Ham Radio operators to beacon their position details to the APRS-IS network using the internet.

The following information is sent in each position packet:

* Latitude
* Longitude
* Speed
* Altitude
* Bearing
* Beacon message (22 characters max)
* APRS Symbol

Now includes messaging between APRS stations.

Within the app you will need to specify your Callsign and Passcode.  Pass codes are only available to licensed Ham Radio operators.

Passcodes can be generated here: www.dstarcomms.com/aprs

Within the app you may change the following information:

* Callsign
* Passcode
* APRS-IS Server URL
* Beacon Message
* Beacon Time Interval
* APRS Symbol for choosing which icon will be displayed on APRS maps.

You may also use this app on iPad devices but a continuous location will be required, normally through GSM or WiFi.

Please note: This app uses the GPS feature of your device.  Continued use of this app may drain the device battery sooner.

Please email matt@dstarcomms.com if you have any feature requests or bug issues.  If you leave feedback reporting an issue I have no way of communicating with you to resolve the issue.

### 5/5 — App working well

*2026-05-18*

I have been using this app for a while now. It’s been working well for me. My only complaint is sometimes the font is too small for me to read (like setting the beacon text). But regardless, whenever I need a quick APRS tracking, I use this. I definitely recommend this app.

### 3/5 — Has potential but needs work

*2025-10-13*

The get APRS PassCode link does not work in the app but got a passcode with Google. They need to add a smart beacon (only sends beacons when moving)

### 5/5 — A 1

*2024-04-26*

Beat APRS I have found that doesnt extort you for a "subscription" or cost an arm & leg.
I appreciate that its not loaded with bloatware "features" that I dont want and dont need.
Clean, smooth, efficient, and does exactly what it's supposed to for a modest price and without the "feature clutter" of some apps that try to be eveything to everyone.
All apps in the store should be like this one.

### 5/5 — Great APRS Beacon App

*2022-02-27*

Works as advertised! Clean interface. Intuitive settings.

### 1/5 — App is broken

*2021-12-22*

Generating passcode does not work.  App is broken.  Do not buy.

### 5/5 — Beautifully Simple

*2021-08-04*

I have used most, if not all of the APRS Applications that can be run on an iPhone. This one is my favorite by far. It is rock-solid stable, and does not muck up the process of using it with a bunch of ancillary, unnecessary, overhead. 

If you are wanting to run an APRS software on your iPhone to serve as a beacon while you are mobile, as well as have the capability of sending/receiving messages, I highly recommend you download and give this particular software a try. Thanks Matt! - NZ4D

### 5/5 — Works great!

*2021-03-16*

The best. I can’t find a flaw in this app. Maybe a switch to keep the screen on full time, or maybe there is one and I just haven’t found it.

### 5/5 — Comoda e funzionale

*2020-07-11*

Fà il suo dovere, permette di essere presenti trasmettendo la propria posizione inviando i dati via internet. Per quel che mi riguarda tutto ok,
Semplice da usare è configurabile a proprio piacere

### 5/5 — Great APRS app for iPhone

*2019-10-04*

I have had this app for a while and use it daily and really like it. The fact that you can send and receive APRS messages are great. The best part is you can change your beaconing icon is great and even apply a message for others on APRS.fi to see.

### 3/5 — TX Only

*2019-08-24*

It sends your position only.  The map is only useful if stationary. If you are in motion you can’t zoom out, it keeps resizing to zoomed in. You cannot see other nearby stations or navigate to them.
