### 5/5 — Simple and effective

*2025-01-14, version 3.4.0*

Love the simplicity of this app. It’s like having an infinite virtual supply of engineering paper with a pencil and eraser. Would be nice to have more shapes than straight lines and ovals for sketches though (e.g. adjustable curves, polygons, etc.).

### 5/5 — Amazing!!!

*2024-12-19, version 3.4.0*

I think that blue sketch is great it’s like a blueprint for my mind I love it!!!!!

### 4/5 — Great

*2024-12-19*

This is a great app even for kids .

### 5/5 — Annoying

*2024-10-07, version 3.4.0*

It is okay but I don’t like that you have to bye Pages

### 2/5 — Yo sus

*2024-08-11, version 3.4.0*

It’s a little frustrating and I don’t know how to delete blank pages

### 5/5 — So easy

*2021-08-26, version 2.2.0*

Love this app. It’s so quick to draw, just the way it should be. No need for my clipboard now. Improvements? I would love to see a TEXT field option, so iOS could convert my left handed scratch to a readable font!

### 5/5 — Can’t figure it out

*2021-06-06, version 2.2.0*

Too difficult to use, deleting it now!

### 2/5 — Hard to use than last version.

*2020-11-23, version 2.0.0*

Nice to met the app last version.

### 1/5 — Rip off.

*2020-10-24, version 2.0.0*

It gives you 20 pages of notes for free. Then it’s $0.99 for 10 pages or $1.99 for 30 pages. There are way too many good note taking apps that don’t charge you per page. I would rather pay a one time purchase of an app than have to pay per page.

### 4/5 — Simple, Elegant, to the point - Although....

*2020-08-20, version 1.2.4*

I love this app. It’s so simple and easy to use. The interface is very straight forward and you can immediate start jotting down your conceptual ideas. HOWEVER... There is no way for you to group something you dont want to erase it, in other words to “massively” erase a bunch of stuff, you have to erase the old fashion way.... Little by little.

There should be an option/feature where you can group elements together to make it easy to delete stuff.

We live a modernize world - and we deserve a modern way of erasing when it comes to our great ideas!

Either way, great app. Love it. I see a lot of usage out of it.
