1. There is no concept of cover page here. 2. Some page templates like cursive writing english, bordered pages etc should be there. 3. An option to add custom template will be best. 4. Please make changing colour of pens little easy as we have to do it very often. 5. Erase objects partially is kept premium which is a little too greedy. Otherwise this app is better than even GoodNote.

2025 Two years now. Still a great app. 2023 I have been using it with my note 9 for a couple of months now. It's made taking survey notes in the field much more neat and organized. I'm using the app with note 23 now. Still is a great pdf app for your phone. I tried adobe 7 day free trial, even if it was going to cost 99 per year. I really love adobe dc on my pC. But it was just to hard to learn the mobile version. Oh and squid cost pennies compared to adobe.

Squid is definitely one of the best things that have happened to me this year. I don't have to carry my notebooks with me everywhere now that I have squid. It's also very easy to use and the free version does everything I need. Big up the squid devs
