The BEST so far! I really Love this app! I tried a lot of different scientific calculators on the store, but I just couldn't put this one down. The one thing I would like to request is the option to swap the ANS button as primary. I use the ANS buttons way more than the DEL button. If you could add in that option, 5 stars for you and my life is complete! Thanks for the great app!

Great app This app you guys developed is just fantastic. I have but one tiny suggestion to make: in the unit converter mode you can select the option 'weight', although it would be more correct to use the term 'mass', for weight is a force caused by the gravitational pull, so if you would only correct that little thing, it would just be great. Thanks.
