The Jot Pro is different, it doesn’t have the same rubber tip like the usual iPad stylus. Though not different than any other stylus, it actually writes the same. Of course Jot Pro tip is smaller followed by a disc that is transparent. Below are comparison between Just Mobile Stylus. When I say it writes the same is all depends on the app. You can write small with any stylus and the comparison between Just Mobile and Adonit Jot Pro is by the Notes app called Notability.
With Notability, I can write fine lines. Adonit website demo a stylus with rubber tip compared to theirs and I find it misleading. The problem with rubber tips is that it’s big and therefore you can’t write in between the lines. But I had no problem with Just Mobile. The precision is strikingly the same, however, with rubber tips, the precision lies on where you want to put down the first drop of ink or in this case, digital ink.
If you are writing in between the lines and you happen to have luck on your hand where you land your rubber tip in between the lines, then good for you. With the Adonit Jot Pro, there is no guessing game. You can see where you will write on your iPad. With rubber tip, your guess is as good as where you think you will write with your index finger.
But if you want to compare writing fine lines, both can do the same, but the only differences is the part where you first make contact with the screen of the iPad. No more playing guessing game with Adonit Jot Pro. Their website site at http://adonit.net/product/jot-pro has more information about Jot Pro.
