Problems with safari in iOS

Anticipating waiting for the iOS App. In the mean time I've been trying to use this app on my iphone in safar however have had a lot of issues. These are three issues I've seen that makes it almost unusable:

Scrolling is very difficult and is not consistant
Copy/Paste seem to be broken (seems to be caught but if I try over and over again it works)
While inserting data it scrolls wildly all over the current note making it really hard to input text

Let me know if you need any more info but all of those are fairly easy to reproduce. Thanks.
