### 4/5 — Great addition for FELX 6600

*2026-04-17*

I had the previous version of Smart MTR and just upgraded to the newest version. I like the setup and control I have over my 6600. My only recommendation would be change background numbers color. Dark blue number on a black deck ground is difficult to see. Maybe a choice between a black or white background. Or change the number to Red.  So far the app works great!
