It does what it says...and nothing more. To pay for it you have to be dumber than someone who voted for Trump... and that's pretty freakin' dumb!
Y make them and list them as paid
Why would anyone pay for this single function temperature conversation app (that doesn't even include all temperature scales - no Kelvin? Really?), when there are plenty of good free conversion apps that handle this and *SO* much more?!? Unit Converter Ultimate is free and blows this app away! (Which reminds me that I really should donate to that one - it's pretty good!) Thanks for making your app free temporarily so I could point this out.
Wow! $1 to tell me the temperature? I can do it free online in 10 seconds! Stupid!
