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!




Platform: PC

Can't export to PDF

This app is *okay* at notetaking, but I cannot export to PDF...even just to Email. I have to export as a PNG and then manually make the PDF! Please fix this

buying the extra tools is alil to costly?

i loved the note taking bit and the folders for each note, but it wasn't worth buying all the extra in my opinion when other apps give you that for free :( i understand wanting to make alil cash from an app c: but the other reviews seem to say its not worth the time/ money spent.

No excuse for not having a save or backup option

The app works wonderfully. Unfortunately, I had an issue with my phone and had to hard reset. I lost 5 weeks worth of notes because of not having a save or backup to cloud option




Platform: PC

Terrible on Windows

Loved the Android version, but the windows version isn't even half baked! For instance, you can't delete a notebook once you created one... no importing of your android notes. and so on.

Don't buy this

This app is terrible in comparison to other similar apps. I am a fan of the android version and it seems they intentionally made the windows version awful. Save your money, don't buy this incomplete app. Even if you buy it, you still have to buy "features" such as highlighting and even then you still can't export your files to pdf. A terrible shame.




Platform: PC

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.

Good writing app but has big limitation

Used Squid for a long time and really liked it. My Android tablet crashed and switched to MS Surface Pro 4. Performed backups every 12 hours and went to restore my Android back up files on my MS SP 4 and got an error. Each time I attempted it would result in an error. I read the Squid FAQ's and it said it could not restore on different platforms. Now it have to export 146MB of data to PDF (if that works) and upload it into my MS SP4. I'm looking into MS OneNote. Its free and it works across any platform, even a PC.

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.

The whole app has crashed on me

My notes broke, they won't load anymore without freezing the app. Lost 8 pages of important notes. This is after I spent money on the additional tools and cloud backup. Very disappointed in this app. Use at your own risk.
