What's New in Lineman's Reference

1.5.0

September 7, 2026

Bug fixes. • Random Loop Phasing: closing the N.O. on a loop that is IN phase no longer blows your cutouts. Out of phase still does — check your phasing before you close. • Sound, Vibrate, Fault Indicator and Random Loop Phasing settings stick between sessions. • Memory no longer piles up as you move between labs.

Think it’s great

I think this app is great for teaching or learning when new to underground power, I think it has a great opportunity to grow and expand on URD devices or systems like thumping wire, service savers and how to set up, cubicles, metering cubicles, or showing more advanced switching with cubicle switches and loops together, or even other URD terminations like t-body’s, potheads, or maybe even splices. I so think it’s a good idea for the secondary pedestal and meter base setup that’s already coming soon. Also adding troubleshooting on secondary may be an idea. Overall awesome app!

Probably one of the most beneficial apps on my phone

I enjoy this app so much, it’s amazing to mess around with this and really challenge yourself. One thing I cannot wait for is the secondary to become available! I’d also like to ask when that’s looking to release?? I’ve been extremely excited to play it.

Really good…Really enjoyable

It’s a decent training tool and great way to spend some time. I’m a PLT and would like to see if there’s a way the dev’s could make some modifications to add another qualified worker as well as have it simulated with an individual. The additional worker would be good cause some utilities mandate that Underground is done in pairs
