Comments on Squid: Take Notes, Markup PDFs for Android

★★★★★ Donna QC · Jul 24, 2026
This is an amazing note-taking app. I've been using it for years. Write with the pen, use your finger to erase. I'm a teacher and use it for marking student rubrics, then I export it to their Dropbox folders and done!! It has streamlined my marking and made my job easier for years!! Thank you!!! Subscription worth it every time. Colleagues are always in awe when I show them how I can edit student work, upload it, then start again so quickly.
★★★★★ Samantha Robinette · Feb 21, 2026
Way better than OneNote for handwritten notes. You can write a massive, mile-long page and the app won’t break when you try to export it as a PDF. It exports everything exactly as you wrote it without cutting anything off, unlike OneNote, which often cuts off your notes during export.
★☆☆☆☆ J. Grey · Jun 29, 2026
Typed text is a premium feature, the free version is essentially useless without a touch screen. If your device has a default notes app, it is almost certainly more capable than this
★☆☆☆☆ Govtofindia BHARATSARKAR · Mar 5, 2026
App maker please give permission import the PDF so that solve question on PDF and erasing by finger without buy
★☆☆☆☆ Jorge Barrera · Mar 17, 2026
For actual features, one needs a premium subscription, which is ONLY a subscription for and not a one-time purchase. Note wise at least has a one-time purchase option.
★☆☆☆☆ Wanda Pareja · Aug 11, 2026
I paid for a Squid account on my IPad, download the app in my mobile and unable to open it. Please advise.
