Comments on Squid: Take Notes, Markup PDFs for Android

★★★★☆ Ashwika · Oct 30, 2025
It's a great app, with hands down the best features found in a note-taking app but the only thing I don't like is that we need to have premium for syncing notes on other device cause like it's the only thing that matters to me in note-taking apps which is syncing option which is not in squid so it's a big turn-off.
★★★★★ 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.
★☆☆☆☆ 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
★★☆☆☆ Brent Bischoff · Aug 12, 2025
The email option is not available in the Share Via menu. This is a must-have featured for me.
★☆☆☆☆ 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.
