v4.2.0
This update brings the new Liquid Glass design in OS26 to Bonobo apps. In Flow, it means the interface fades back so your page is the focus. The menus feel lighter and more flexible, giving you more room to create.

• Floating top menu: The main menu now hovers above your page so your canvas fills the entire screen.
• Expanded Menu option: In "Interface Options" you can toggle "Show Expanded Menu" on or off. When it is on, buttons like "Layers", "Sharing", "Export" and "Import" are shown across the middle of the screen for quick access. When it is off, those buttons are available from the drop down menu at the top left of the screen.
• Liquid Glass design: Panels can now match your document’s Paper color, switch to Black, or use Liquid Glass. With Liquid Glass the interface melts away even more as you see through it to your canvas. Adjust tint, frosting, and shadows in "Interface Options".
• Command Menu on iPad: Swipe down from the top of the screen to quickly access common features.
• Enhanced windowing on iPad: With OS26 you can now resize and position Flow windows more precisely for better multitasking.

And in case you missed it:
• Crayon tool: A new drawing tool that gives your lines a textured, hand-drawn feel. It is fun to sketch with and perfect for adding personality to your notes and illustrations. Find it at the bottom of the Tool Editor.
• Reference Images: Pin an image above your page as a temporary overlay for inspiration or notes. Use it to trace details, match proportions, or pull out colors. Drop in images from other apps or tap the Add button in the top menu. Flow will automatically show key colors from the image, which you can tap to use with your current tool or import to your palette.

Flow 4.1 brings a brand-new drawing tool, smarter ways to work with colours, and refinements that make creating in Flow even smoother.

Crayon
Meet our newest drawing tool: the Crayon. It’s fun to use, with a rich, textured look that’s perfect for adding warmth and personality to sketches, notes, and illustrations. Find it by opening the Tool Editor and scrolling to the bottom of the tool types.

Colours
Create colour variations
When you tap Add Colour in the Colours Panel, you’ll now see tint, shade, and harmonic variations — giving you quick, ready-to-use options without having to adjust them manually. To tidy up, simply press and hold on a colour until it pops away.
Create colours from an image
Turn inspiration into action by generating a colour set from any image. Open the Colours Panel options menu, tap the image button, and Flow will pick the most prominent colours so you can instantly create palettes that match your photo, artwork, or design mood.

Reference images
Keep your reference material right where you can see it without cluttering your document. Pin images above your page by dragging them in from another app or using the Add button in the top menu. Reference images stay visible while you work but aren’t saved to your document. Key colours from the image are shown automatically — tap to use one instantly, or import them all. The Colour Eyedropper works directly on reference images. You can also “pop out” an image from your document: select it with the Lasso Knife, then tap the pin icon.

Pencil Pro squeeze
Apple Pencil Pro users can now customise the squeeze gesture to switch to eraser, select with the Lasso Knife, or open the Tool Editor — so your favourite tools are always just a squeeze away.

UI panels
Boost the size of tools in the Tool Dock and colours in the Colour Panel for easier selection. On iPhone in Pencil Case mode, tools display larger for better visibility. All panels (Tool Editor, Tool Dock, Colours, Layers, Pasteboard) can now match your page colour for a cleaner look.

Pasteboard
Resize the Pasteboard Panel to suit your workflow. Narrow for a single-column view, or expand to two columns for larger previews.

Layers
Resize the Layers Panel from its corner for better visibility. The dock button remembers your last-used side, with a quick switch button when docked. Delete layers instantly with the new button beside the add button.

Also in this update
	•	Updated menu bar and unified panel borders
	•	Better Tool Editor visibility on low-contrast backgrounds
	•	Smoother size and opacity adjustments with more responsive colour feedback
	•	Larger panel drag handles and ruler grips
	•	Faster scrubber updates when editing pages
	•	“Pen Sets” renamed to “Tool Sets”
	•	Removed long-press gesture from Tool Editor tool type button
	•	Updated Colour Eyedropper animation and look
	•	Added a fun new hidden effect
	•	Updated app icon

We think of Flow as the ultimate time machine. When you’re drawing or writing without distractions, time disappears. That Flow state is what drives our design — every tool, gesture, and interface choice is made to help you reach that moment. Our whole Bonobo team is proud to keep building toward that goal. Email us at flow@bonobolabs.com to say hi, and join our tester group at beta-signup.bonobolabs.com to chat with us on Slack.

Squeeze your Apple Pencil Pro (or double-tap with Apple Pencil 2nd gen) to open the all-new Quick Menu — a floating arc of actions like Undo, Select, and Eyedropper. It appears right where you’re holding your Pencil and dismisses automatically after use. Barrel Roll is also supported.

– New Tool Setup & Line Smoothing
Fine-tune how each tool feels with pressure curves, line smoothing, ink flow, and more. Live test changes on the scratch pad.

– Revamped Color Sets
Create and save your own palettes with unlimited colors. Each document has its own. Tap to activate a color, or tap again for advanced options.

– Updated Tool Dock, Editor & Horizontal Layout
Float and snap tools into new horizontal layouts. Everything feels smoother, faster, and more responsive.

– Smarter on iPhone
Cleaner layout, auto-hiding interface and optional smoothing for finger drawing.

– Streamlined Document Setup
Name, preview, cover image, page style, and color — all in one place.

– Auto-hiding panels
Panels now slide out of the way when your Pencil gets close. More space, less clutter.

– Cleaner Collections
A cleaner layout makes it easier to browse and manage documents — with clearer thumbnails, better buttons in List View, and a new floating Add button in the top right.

– Floating Undo
An optional quick undo button appears where you last drew — fast and gesture-free.

– Image Playground
Generate original images directly in Flow and drop them into your document.

– Virtual Tool
See a mirrored on-screen Pencil for demos and screen recording. It’s weirdly fun.

– Collaboration updates
Clearer indicators show where others are drawing in real time.

+ Dozens of smaller improvements and bug fixes
Refined ruler controls, better Pasteboard, layer panel polish, smarter animations, and more. Lots of bug fixes including some sneaky obscure ones. Adam loves hunting down those and we love him for it.

Thank You

We think of Flow as the ultimate time machine. There’s a special kind of magic when you’re drawing or writing and nothing gets in your way — time seems to stop altogether. That feeling of being in your Flow state is what drives our design. Every tool, gesture, and interface element is crafted to help you reach that moment more easily. The whole Bonobo team is incredibly proud to build toward that goal.

This update clears out some unneeded files to trim down the app size a little—just a bit of spring cleaning.

Behind the scenes, we’re working on something big. If you’d like to get early access and help test the upcoming release, sign up for the beta at https://beta-signup.bonobolabs.com

This version fixes an issue when importing HEIF format images.

Our eagle-eyed customer Frank spotted it (thanks Frank!), and Adam hunted it down and fixed it.

Frank was using Flow to draw on top of photos—which is great fun if you haven’t tried it yet. You can even snap a photo right inside the app. It’s perfect for journaling, sketching ideas on a renovation or garden plan, helping kids label parts of a diagram, or just adding a personal touch to a photo before you share it.

Version 3.7

Company name change. Our brand collaboration with Moleskine concluded in 2025, and the apps are returning to their original brand, Bonobo. The app names themselves are not changing— Flow is still Flow. The same team that has been designing and developing the apps since day one remains 100% unchanged—only the name is reverting.  For more information, see our website or send us a message.  We’ve been working on some great new features – stay tuned!

Version 3.6:

• Various small fixes

Version 3.5:

We have some exciting new features in this update:

 • New Control Center buttons that allow quickly creating a new document, or opening the app to a particular document - e.g. for quickly accessing your scratchpad / quick-note doc right from the control center.
 • Support for the new tinted app icons and widgets
