Best Drawing Apps for Keeping Separate Sketchbooks and Projects

For drawing apps with separate sketchbooks, consider Paper for page-based journals, Concepts for folders and subfolders, Linea Sketch for project folders, or Smudge for multiple notebooks of rough ideas. All four have iPhone and iPad versions. Choose by how you want to browse your work: a notebook for each theme, a folder hierarchy for larger projects, or grouped sketches. There is no single best fit for everyone.

Disclosure: this guide is published on Smudge's website. It compares documented organization features, not hands-on performance scores. Official documentation and US App Store listings were checked on October 24, 2026. Features, compatibility, and purchase options can change.

Which apps let me keep personal ideas and different projects separate?

The distinction is organization between drawings, not layers within one drawing. You might want a personal doodle book, a garden-planning project, and a collection of holiday-card ideas. These apps offer different ways to keep those collections apart.

Is Paper a good choice for a drawing notebook with separate journals?

Paper's official help documents creating journals, adding pages, and browsing in page or grid views. You can also attach a written note to a drawing. That makes it a candidate for a travel sketchbook, visual diary, or project whose drawings benefit from short explanations.

Its organization is book-like rather than file-like: open a journal and browse its pages. If that is how you think about your work, start here rather than choosing a large toolbox solely because it has more features.

The limitation is the paid boundary. Paper Pro includes Journal Sync, premium covers, default page templates, and private journals. Do not assume the base download includes every customization or cross-device feature you need.

How does Concepts organize projects, drawings, and folders?

Concepts' current Gallery manual describes folders and subfolders, with grouping and sorting by names or dates. It also documents dragging drawings between folders and adding a folder description. Older guides may say “Projects” and “Sections”: the Concepts 6 release notes explain their replacement with folders and subfolders on iOS.

For example, you could create “Home renovation,” then subfolders for kitchen layouts, lighting ideas, and furniture studies. That is a suggested structure, not a preset supplied by the app. Concepts suits this kind of hierarchy more directly than a flat shelf of notebooks.

The trade-off is scope. Its iPhone and iPad listing describes an infinite, vector-based canvas, with selection and editing tools among paid features. That flexibility may be useful, but it is more than you need if all you want is a blank page for casual doodling.

Would Linea Sketch work for grouped project sketches?

Linea's listing documents project folders, thumbnail previews, and sharing, renaming, or moving drawings within projects. Its official site also documents collections that group projects. You could use separate projects for individual ideas, then collect related projects under a broader theme.

A useful distinction is output: Linea's tips explain exporting an entire project, or selected sketches, as a multi-page PDF. Consider that if you want to print or share a sequence of project drawings rather than export each separately.

Linea balances that organization with a focused drawing toolkit. The concrete limit is its five drawing layers, which may not suit illustrations requiring many independently editable elements.

When does Smudge's multiple-notebook approach make sense?

Smudge: Imperfect Sketchbook documents multiple notebooks and a distraction-free canvas. It is a reasonable option for keeping personal ideas, practice drawings, and different rough projects in separate books without choosing a professional project-management workflow.

The listing also documents finger drawing on iPhone and iPad, Apple Pencil drawing on compatible iPads, and iCloud notebook sync. Apple Pencil is not an iPhone feature.

Its real limitation is compatibility: the current app requires iOS 26 or iPadOS 26 or later. It also includes in-app purchases, so check the current offer rather than assuming every feature is free. See Smudge's notebook overview if that approach matches how you like to collect unfinished ideas.

How should I choose between notebooks and project folders?

Try a small organization test before importing your whole collection:

1. Create separate spaces for personal ideas and one active project.
2. Add a few disposable drawings to each.
3. Check whether you can find the right collection without scrolling through everything.
4. Try the documented rearranging or exporting workflow you expect to use regularly.
5. If switching devices matters, test syncing separately from organization.

Choose Paper or Smudge when the notebook metaphor appeals; Concepts when you need nested categories; Linea when grouped sketches and project PDF export matter. More structure is only helpful if you will actually use it.

What else should I know about separate digital sketchbooks?

Are separate notebooks the same as private notebooks?

No. Sorting personal and work drawings into different collections is not evidence of access protection. Paper explicitly documents private journals as a Pro feature. Check an app's privacy controls separately if that is a requirement.

Will my project folders automatically follow me from iPhone to iPad?

Not merely because folders exist. Concepts distinguishes local storage from iCloud Drive, while Paper lists Journal Sync under Pro. If device switching is important, read our iCloud sketchbook comparison and verify your chosen app's current setup.

Can I organize drawings if I already use Procreate?

Yes. The Procreate handbook documents named Stacks that group artwork, including moving drawings into and out of a Stack. You may not need a different app just for organization. If you want fewer drawing controls as well, see our simple iPad sketchbook guide.
