## Most critical reviews (10 lowest-rated)

### 2/5 — Good start

*2010-10-06*

A nice app but needs a lot more.  I would delete the top section and expand on the middle section to include additional RF and dB conversions.  It will then become a nice and handy tool.

### 2/5 — dB

*2009-09-25*

Bis auf ein redet oder clear Button der fehlt, ist alles okay. für 79 Cent bietet das App. leider zu wenig settings. Update der Bedienung und weitere . Wünsche mir ein update mit einzelner db Berechnung bei der zwischen Pegel dbspl dbu Pa USW. geswitcht werden kann.

### 4/5 — A handy app

*2009-11-21*

A handy app for E.E.'s, but personally I'd drop the Neper to make room for V1 V2 fields in addition to the ratio field.

### 5/5 — Several year user

*2024-06-09*

Been using for five years for repeater maintainence. Quick and easy to use. An amazing range of tests and scales. I couldn’t work without it since I retired my slide rule. The battery wore out(!).
