I am using the android version of this app for 2 years now for taking notes at classes. It is amazing. However the windows version need a lot of work. I was thinking about getting a surface but no way I would ever pay for this performance. Every single time that I use this app I would at least get 1 error. I can never share my notes properly. Please, please fix this via update.

Save your money & get a real notebook

[update] Dropped it 2 stars because you can't swipe through pages in a notebook. Horrible UI decision, I've been using a Moleskine instead. Save your money & get a real notebook. [/update] Squid is still better than OneNote (too many menus, too many options, two different apps), Scrble (blah), Metamoji Note (overpriced with a mediocre UI) and Bamboo Page/Paper (why two mediocre apps instead of one good app?). Plumbago is new & promising but needs features. Pros: - Importing images - taking audio notes (very cool) - selecting & changing line color - Way better zoom handling than the competitors (except TruNote) Cons: - no swiping between pages - Global default paper style only - can't set paper style per notebook (SO IRRITATING) - no true export (can't save, can only export to another app as an attachment - how friggin bizarre) - too many clicks & swipes to go from page to notebook to home screen - limited paper choices - the lasso tool only selects in rectangles

Horrible Program

You can't save notes because it is supposed to auto-save everything. I created a seven page lecture note that it did not save. It shows the seven pages but it blank! Lost my notes for an entire lecture!

Delete & PDF Export

The "delete" option doesn't work. Long press will not select, can't delete any notebook. PDF Export to Dropbox does not work. JPG and PNG do, but PDF does not. Should also be able to save to the computer's hard drive.

Choppy writing when page size is set

i5 SP4 - The writing is perfectly smooth when the page size is set to infinity, but as soon as you change the page size to A5 or any other size, the writing is choppy all of the sudden. If the writing was always smooth, like it is in the Bamboo Paper app, Squid would be the best note taking app there is for Windows 10, by far. And I, as well as others I'm sure, would buy all the add on packs if this one simple problem was corrected. I want to use this app, I just can't if the writing isn't smooth. Here that devs? I will give you my money if you fix this!

Paid $2.99 for in-app Tools upgrade. Still not available in app. Asked developer why. Still no reply. Was I ripped off?

Simple and easy but...

This app's great feature is saving to PDF. But it will only email. Needs option to save to local system as PDF.

Needs Swipe to Turn Pages

To get from page to page is a pain, with Windows version and on Surface Pro 3/4. Hate to have to pull down and hit little buttons to turn the page. It gets worse on high dpi resolution Surface Pro screens, impossible to do a presentation using this if you need to get from page to page.

No Google drive support/auto save

This is a wonderful app but it lacks Google drive support and autosave, which in my opinion are critical flaws. I purchased all PR.emium perks and expected a higher degree of premium options like the aforementioned options, however this is not the case. I hope this changes in the future as this writing app is my favorite app for note taking in medschool
