### 1/5 — Gives completely wrong impedance values

*2023-04-04*

I bought app specifically because the description said it would give you the specific coordinate values, including the magnitude and angle of the impedance and I wanted to get precise values instead of estimating from a paper chart.  Well it does do that, but the values it gives are utter nonsense.  I have no idea where it’s getting its numbers from, but they have no clear relationship to the actual coordinates on the chart.  I’m very disappointed.

**Developer response:** Hello, I’m sorry for this, please contact me with the email support to solve. Anyway the values you see are correct, the ones that appears on the top right corner tapping on the chart are denormalisied (multiplied by 50ohm): The ones on top are the modulo and phase, on bottom the corresponding impedance, then the values on the red dot are the Cartesian coordinates relative to the plane. Again, if that does not makes sense, please contact me. Thanks.

### 5/5 — nice

*2025-08-20*

can you add the Y version of smith chart as well

### 5/5 — Nice try but the lines (all) appear zigzag when zooming in.

*2022-09-24*

Nice try but the lines (all) appear zigzag when zooming in (or without zooming in). Could you please try fixing this big flaw so I can start using my iPad Pro 12.9” (2018) for this application? 

Overall, lines don’t look good. 

With Kind Regards!!!

**Developer response:** I really appreciated your comment. 
Soon an update will fix this issue. Thanks!
