When you use a digital planner, you want to do just like you would with a paper planner (or maybe beyond). You want to scribble, squiggle, add shapes, highlight, underline, add notes, and what’s not! Best digital planners like Print Magic Studio X also give digital perks like customisable templates, audio notes, the ability to add stickers and images and create hyperlinks.

But you need the right annotation app to make the most out of the best digital planner. Such apps are a fun and paperless way to keep up with all your to-dos and stay productive as planned.

Let’s check out 6 tried-and-tested annotation apps for digital planning. 

1. GoodNotes – Complete Annotation App for Digital Planning

The app ranks at the top of this list because it has everything you need for fun and effective digital planning. The standout feature is its abundance of organisational and customisation tools that make the lives of super-messy users like me a whole lot easier. 

Choose customisable templates, customise the toolbar, create lively drawings with Pencil, the Eyedropper colour picker, and scribble to erase handwriting. You also get a powerful search function, AI-enabled tools, onboard handwriting recognition, and much more.

The experience doesn’t stop there. 

The natural handwriting experience makes it popular among those who prefer jotting down notes by hand. Apple Pencil makes notetaking feel even more natural and intuitive, making GoodNotes a prime choice as the best annotation app for digital planning.

Notability is a multimedia-rich annotating experience. Besides basic annotating tools like highlighting text and using text boxes, you can also use a stylus or your fingers to handwrite or hand-draw just about anything on your planner.

What’s more impressive about Notability is that you get a huge collection of customisable digital planner templates across all aspects of life: fitness, home chores, weekends, office, and more. Have fun adding GIFs, sticky notes, web clips, images, and even video clips to your digital planner.

Notability is well-known for audio syncing with handwritten notes, but other apps have got this feature, too. Notability’s differentiator is audio transcripts — time-stamped text of your recordings.
