If you have one of the latest versions of iOS, use “Cherkalka”.
The app for drawing and storing sketches with cool interface and lag-free work. Works on all devices: from the 1st generation iPhone to the latest iPad with the Retina display and iPhone 5.
Drawings from the app can be saved to the clipboard and Photos.
This app is not a graphics editing program, but "paper and pencil" in your device.
Ratings and Reviews
Perfect for a quick note taker
I've been searching for something like this and finally found it. Ideal for taking quick info such as a name or number or brief info like an appointment time and date.
Nice features, responsive. Better than some paid whiteboard apps.
This sketch app is great. I love the UI for it. Old school iOS layout. Very enjoyable
With Family Sharing set up, up to six family members can use this app.
