### 5/5 — Best model train app available

*2026-05-26*

The Blunami app is by far the most developed, most intuitive, and most comprehensive app anywhere for controlling a model train. Every decoder made should come with an app that makes it this easy to customize your sound decoder. I love that I didn’t need to read a manual or watch a bunch of videos to figure out how to use it.

### 5/5 — Game Changer

*2025-11-15*

The Blunami decoder is the cutting edge doc decoder.  You no longer need expensive doc controllers just hook up a 12 volt  dc  power like from a laptop and run trains with your phone!  The new app version makes programming a breeze.  You no longer need to figure out CVs.  The app provides you the ability to find the item spelled out ( no need to remember which CV controls the coupler) and in most cases you have a slider and number input to make the change.  No more programming track.  Genius.  

Looking forward to more updates though.  In multiple-train mode the function screen covers the left most throttle so you can’t see where you are at speed wise.

### 5/5 — Function issues fixed

*2025-11-08*

Works great and Soundtracks tech support is great

### 5/5 — Function menu issues

*2025-09-17*

App will not allow  you to close the function menu
