Comments on Squid: Take Notes, Markup PDFs for Android

★★★★★ Menassie Ephrem · Jun 25, 2025

Excellent app for writing. I take all my notes on Squid. I teach at a university, this is the app I used to teach online classes and make YouTube videos for my students.

★★★★★ Lee Maclin · Nov 20, 2025

So much useful functionality! This is the note-taking app that killed my reliance on paper.

★★★★★ James Campbell · Jul 12, 2025

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 too hard to learn the mobile version. Oh and squid cost pennies compared to adobe.

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.

★☆☆☆☆ 飞一般Tiger · May 25, 2026

To import PDFs is not free, so I uninstalled.

★★☆☆☆ Brent Bischoff · Aug 12, 2025

The email option is not available in the Share Via menu. This is a must-have featured for me.

★☆☆☆☆ Evan Sims · Jul 29, 2025

Wasn't there a feature to cut-and-paste full pages Edit (reply to response): Read the page, that's how I remember it the click and drag to move pages is not working

★☆☆☆☆ 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
