It's a nice quick conversion, but I almost NEVER get the back button so that I can enter another figure for conversion. I have to back out all the way to the beginning. I'm still, for example, exchanging celcius to farenheit, but instead of putting in a different Celsius number with a back button directly on the numeric screen I have to use the actual back button of the device. This only seemed to begin a year or so ago. For some conversions like temperature, never get the back arrow at all now.

A really useful app. I use it all the time for different needs. The one change that would make sense and save time is the following: let's say I want to convert kg to pounds and also to stones. I have to re-enter the kg data twice and do 2 separate conversions. A button or drop down list to switch to pounds or stones or another resulting units would be really helpful! This should be a general solution so as to be applicable across all conversions offered. Thanks 👍

Good app but constant error message that there is a newer version available. Some of the input screens do not allow you to backspace if you make an error or want to enter a new figure. You must go all the way back and start over. Other input screens do not allow decimal inputs. Could use some tweaks.
