## Most critical reviews (6 lowest-rated)

### 1/5 — No negative dBm

*2016-09-23*

Useless or unfinished

### 5/5 — Handy app but need a minus sign for entry

*2022-07-12, version 1.3*

This is a great app! It would be perfect if there was a way to enter a negative number such as -120 dBm. 

Radio work sometimes needs to convert from -dBm to micro volts (uV) and the reverse. I’m sure it would be greatly appreciated if these converters were added. 

Also, others may need to change the impedance to something besides 50 ohms. 

Thank you for an excellent app!!

### 5/5 — Simple, fast, super useful tool.

Very good and useful tool for everyday use. Thanks!

### 5/5 — Perfect

*2011-04-28, version 1.1*

It's simple to use, gives all the information I need in a clean, easy to read interface. I use it all the time. And at this price (free) it's a steal. 

Thank you for your work, and I look forward to seeing other projects you do.
