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.

Its a great app, with hands down the best features found in a note taking app but the only thing I dont like is that we need to have premium for syncing notes on other device cause like its the only thing that matters to me in note taking apps which is syncing option which is not in squid so its a big turn off.

This is your basic note taking app that does the job, but doesn't feel like it's going above and beyond like some others of its kind. The subscription price is low, which is nice, but I think there would be a lot more done with this one. Other apps have far more tools, each with more options (without subscriptions), and there are templates, and other features that make note taking better.

The devs have a lot of nerve to ask for a subscription for an app that feels like something from ten years ago and with so few features. What's up with portions of the document not being visible when scrolling?

I just tried this app on my e-ink tablet. The app itself has a lot of the features I've been looking for & has a very clean interface. However, when I came across the desire for a feature that must be paid for I found out that the only way to get the premium features is to pay a subscription. I immediately uninstalled the app. I refuse to be tied to a subscription, & recommend to any artist (professional or otherwise) to avoid subscription whenever possible. Too bad that greed got in the way
