### 5/5 — 20+  year Level 2 RT Tech review

*2026-03-31*

There is a LOT of great info here. Being able to manually type in the wall thickness or being able to select the pipe data makes using this app a breeze. The IQI selector is spot on and will help to make sure you select the right one for the job. The code references are very thorough and eve accounts for the big change included into the 2024 edition of b31.3 NFS (IP and LOF is now acceptable, see code or app for exact criteria). There is also an image density correction calculator that is extremely handy if you over or under shoot a shot and need to adjust the time either way.

**Developer response:** Really appreciate you taking the time to write this — seriously.
That was the whole goal with the app… make it something you can actually use in the field without fighting it. Being able to either punch in your own numbers or just pick the pipe and move on is exactly how it should be.
Glad the IQI selector is doing its job too. That’s one of those things that can bite you if it’s off, so I wanted it dialed in.
And yeah, the 2024 B31.3 changes were a big one. I made sure that got built in right so guys aren’t stuck flipping through code books trying to figure out what changed.
The density correction tool is one of those “you don’t think about it until you need it” features — but when you do, it saves your day.
Appreciate the feedback and support. I’m building this off real field use, so stuff like this helps more than you know

### 5/5 — So Cool!

*2026-03-21*

Phenomenal app! So glad it’s a one stop shop for all NDT needs. Excited for the API section to be updated soon!

**Developer response:** Glad you’re enjoying it—really appreciate that!
v1.0.9 is bringing a major upgrade to the API section with expanded tools, quick calculators, and more field-focused references. Update should be live in the next day or two!
