See It In Action

Watch it work

Every section of the app - on a real phone, in real time.

Situations
"I want to understand why a link passes or fails before I'm standing on a job site guessing."
Run the loss calculator and read the breakdown. It shows you exactly how fiber length, connectors, and splices each contribute to total loss. See the math work once and it sticks.
Loss Calculator
"My lead handed me an OTDR trace. I have no idea what I'm looking at."
Open the OTDR Guide. Every event type is listed with what it looks like on the trace, what it means, and what to do about it. Most techs look at it once and it clicks.
OTDR Guide
"I keep running into the same faults and I want to actually understand what's causing them."
Work through the Fault Troubleshooter. Each step explains the reasoning behind it, not just what to check, but why that check matters. Run it enough times and you stop needing it.
Fault Troubleshooter
What's Inside

Learn it right. Use it in the field.

Every section is built around field reality. What you actually run into, and what actually fixes it. The more you use it, the less you have to guess.

Fault Troubleshooter
Learn to diagnose faults systematically instead of guessing. Each step explains the reasoning, so next time you already know where to look.
OTDR Event Guide
Learn to read every event on a fiber trace - what it looks like, what it means, and what to do. Connectors, splices, bends, breaks, and reflections all covered.
Reference Tables
Searchable specs for connectors, fiber types, jacket ratings, and constructions - with plain-language explanations of what each spec actually means.
Splicing Guide
Full coverage of fusion and mechanical splicing - step-by-step procedure with the reasoning behind each step, cleave quality assessment, and common failures explained.
Built from experience. Priced for everyone.
One-time purchase. Works on any phone, tablet, or computer. No app to download, no account needed. Open the link and go.
