蘋果鉛筆可以讓iPad更接近在紙上寫字的體驗。鋼筆能提供一種壓力感，就像鉛筆一樣。文筆輕快時筆跡較淺，筆力稍大時筆跡較深。
當你用蘋果鉛筆寫字時，iPad會自動禁用觸控式螢幕，你的手可以直接放在螢幕上，不用擔心誤觸。
本質上，電容筆只是一個導體，從而延伸人體的觸控式螢幕，形成耦合電容效應。所以當你在上面寫字的時候，手的觸控和手的觸控沒有區別。只有將觸控式螢幕的手換成相當於導體的筆，才能提供在紙上寫字的體驗，如果手觸控式螢幕，就會誤觸。
如果想用電容筆在iPad上畫畫，通常需要戴上防觸控手套，這樣才能實現與觸控式螢幕的物理隔離，而且電容筆沒有壓力感應功能。
First of all， I don‘t recommend you to buy alternatives， because alternatives only make you give up learning on the iPad or buying a pencil
Apple pencil can make the iPad closer to the experience of writing on paper。 The pen can provide a sense of pressure level， just like a pencil。 The handwriting is lighter when writing gently， and deeper when writing with a little force。
When you use Apple pencil to write， the iPad will automatically disable the touch screen， and your hand can be placed directly on the screen without fear of false touch。
In essence， the capacitive pen is just a conductor， so as to extend the touch screen of human body and form the coupling capacitance effect。 So when you write on it， there is no difference between the touch of hand and the touch of hand。 Only changing the hand touching the screen into a pen equivalent to a conductor can not provide the experience of writing on paper， and if the hand touches the screen， it will touch by mistake。
If you want to use a capacitive pen to draw on the iPad， you usually need to wear anti touch gloves， so as to achieve physical isolation from the touch screen， and the capacitive pen has no pressure sensing function。
