Pros and cons of Units Convertor app for iPhone and iPad

Units Convertor app good for

nice program Ive been looking for a while. nice user interface. only 4 stars because theres a mistake: temperture in kelvin cant be negative .
Clean and simple. Does exactly what you expect without clutter.
Its free so no complaints, but a note to the developer: you can easily add more in updates so why not add conversions for baking, such as cups to oz. etc grams, and of course as stated already add mm. Thanks for the app.
Free and works/look great. Even some regular flip cellphones have it so I would never pay for an app like this. Good job
At least its free as all unit converter apps should be. Thanks for this. Still needs more units and speed!
Simple and functional, works great. With additional units and conversion type added over time. However, I find the clicking sound when selecting the units annoying, especially when Keyboard click sound is disabled in settings. Shouldnt the application be following the system settings?

Some bad moments

hmmm, did 14 of the developers friends write 5 star reviews for this?? This is a unpolished, incomplete app. Typos, missing obvious units and conversions, although developer does say these are being improved. Units are arranged alphabetically rather than in a more logical order (e.g. grouped by metric/imperial or in increasing magnitude, etc). keyboard entry allows any arbitrary character (letters, punctuation) into the number field for conversion - simple details like this could use some attention in next version.
Dont buy this App, not as useful as the "units" app which is also $0.99 and has more features, Dont bother with this bad app...
The only reason its so popular is because it used to be free. This app is nowhere near the calibre of Units app. Buy Units instead. This app should have stayed free.
Tried the free version before they started charging. The interface is unnecessarily tedious and slow to input numbers. The best and comprehensive unit converter is the iconvert, although its a broswer-based app, it does NOT require internet access after youve used it once (you can configure for off-line use), its fast, and it does 28 *categories* of unit conversion.
First of all it is not free. Second it does not work at all. Save the $
This used to be free and as such was ok. But now as a paid app. It does not meet expectations
