I recommend this

Tayasui sketches has one of the best interfaces presented to me by any drawing app ever. It is perfect. Best interface, brushes and overall feel!

Although, recently, on my iPhone, I have not been able to open it because of constant crashing.
On iPad, the app is bug free, but, even after updating, I am not able to find the screen recording system.
Ive been a big fan of this app for about a year now and havent found anything better. Up till now, it has never even crashed. I know the Tayasui team will fix this soon and it will once again become the best drawing app of all time.
