## What is DMR Tool?

Please Note: Any reports of the data not being real-time is inaccurate. The data provided in this app is taken directly from the UK C-Bridge and is 100% real time.

With the massive boom in DMR users registering on the Ham Radio DMR MARC network we look at different ways of providing real-time status information from the network.

Using DMR Tool puts in the hand of the user the following features:

* User Tracker (Useful for when mobile and roaming, allows user to see repeater and RSI stats)
* World Wide DMR ID User List (Easily filterable using the inbuilt search feature)
* Last Heard by UK Repeaters
* Last Heard by any European Callsign
* A visual map showing repeaters located in the UK which are connected to the UK C-Bridge (This will expand over time)
* All last heard data is real time and each last heard screen will automatically refresh every 10 seconds.
* Static data, such as the repeater list and the global DMR ID list is updatable from within the app.  The UK Repeater list is managed by us on our servers and the USER ID database is downloaded directly from the DMR-MARC database so to ensure you have the latest data.

Any feature requests or to report incorrect data, then please contact us directly: matt@dstarcomms.com

### 1/5 — Total Ripoff

*2025-06-13*

Doesn’t work - continuous Server may not be operating - only for the UK. Misleading!!!!😡

### 1/5 — KR4avc

*2025-02-01*

App does not work , server is never connected to update the repeater database. Nothing else can work without it.

### 1/5 — Do not buy it don’t work

*2023-10-27, version 1.5*

It simply doesn’t work and got charged 99p to use up  space on my phone!!

### 1/5 — Don’t buy this

*2022-08-29, version 1.5*

I’ve just bought this and it crashes, doesn’t update, my local DMR repeater is not on here and can’t find myself in the user database. I had my DMR ID for over 6 months, and I’m not in the database of this app. DONT BUY THIS!!!!

### 1/5 — DMR

*2022-01-22, version 1.5*

This app dose not work

### 1/5 — Rubbish

*2021-09-11, version 1.5*

Not worth it useless should be taken off the Applications list

### 1/5 — Oh dear...

*2021-04-17, version 1.5*

Unfortunately this app appears to have died...

### 1/5 — Not particularly good.

*2020-08-17, version 1.5*

Most features either say ‘server offline’ or the crash the App. ( Unusable on the latest iOS on iPhone XR )

### 1/5 — Absolute Shocker

*2020-04-15, version 1.5*

Crashes when selecting ‘Users’.  Fails to list details of users accessing Phoenix repeaters.  Cannot find my DMR ID in ‘last heard’.  Basically this app does not work - don’t waste your money on it.

### 2/5 — Needs updating

*2020-03-27, version 1.5*

This app used to work well but the latest version seems to lag by about 6 hours on the Last Heard screen and the user database does not seem to have been updated in the last 18 months as only my callsign issued 3 years ago is on there (the next two are not).

It also give the “server may be offline” message all the time so I can’t check on when a call sign was last heard.
