Oh snap, it's a new update for Flow and it's all about making straight lines and perfect shapes. Actually, it's not all about that, there is a bunch of other cool stuff too like a brand new brush tool and updated Tool Designer.
Here's what's new:
- Snap perfect lines and shapes. Flow can now detect what you've just drawn and turn it into a perfect straight line or shape. After drawing a stroke, simply hold still for a brief moment without lifting up. Flow detects straight lines, curved lines, rectangles (including squares), circles, ellipses, and triangles. Nearly straight lines snap to perfectly straight and let you drag the end point around, snapping to horizontal and vertical as you get close. You can even enable a menu that pops up to add arrows and dots to the ends of your lines. Find the preferences in the Drawing and Gestures settings.
- Redesigned ruler. The ruler now comes in two modes: Simple and Technical. The new Simple ruler puts a ruler object on the page that you can drag around, rotate with two fingers, and draw along its edges. Tap the magnet icon to snap rotation to 5 degree increments, or tap the rotation handle to set it perfectly horizontal or vertical. The previous design lives on as Technical mode.
- New Flat Brush tool. Similar to the round brush pen, but with a wide flat brush tip that can be rotated and a more pronounced faded edge.
- Updated Tool Designer. The Tool Setup screen is now the Tool Designer, with a new interface that lets you choose the size, opacity and color to try out on the scratch pad as you fine tune your preferences.
- Better eyedropper. It now does a better job of picking the right color you drag over, with a new setting for grabbing the exact color on the page or the original tool color, and a new one finger press + draw gesture to bring it up.
- New stroke width fluctuation model. Strokes now vary in width organically with a more natural feel that stays consistent at any zoom level, adjustable in the Tool Designer.
- New stroke fade control. Choose how a tool fades in and out as you draw with it, in the Tool Designer.
- New menu for Fun Options. There is a new menu on the main menu just for the fun things. What are the fun things, you ask? Take a look. Got a fun idea to add to Flow? Let us know!

4.6.0 3 Aug
This release squashes a rendering bug that could make strokes flicker or briefly glitch while you draw. Small update, big difference. Details below.
Fixes
- Fixed a bug where strokes could flicker or momentarily look garbled while drawing during long sessions, caused by the canvas reading a stroke before it had finished updating.
- Made drawing more stable during fast, continuous note-taking, especially on busy pages with lots of strokes.

4.5.3 26 May
With the new Flow drawing engine now live, this update brings a bunch of great interface improvements to go along with it. Snappier menus and cool new features like resizable panels, a better way to choose pen sizes, and a handy scratchpad.
Questions? Talk to us at flow@bonobolabs.com
Here's what's new:
Drag and resize the Pen Dock
Move the Pen Dock anywhere by its grip, or drag near the bottom to snap it horizontal. A new resize bar makes it as tiny or as big as you like, and overflow tools and pens scroll together.
Drag the Pen Editor anywhere
The Pen Editor moves anywhere too, and snaps to the top rotated horizontally.
A new pen size picker
The size picker is now more of a slider than a wheel. All sizes are visible at once, so it's faster to choose.
Scratchpad for testing tools
A new button turns the area around the Pen Editor into a place to scribble and try the current pen.
Quick share from a Lasso Knife selection
The selection's floating panel has a new export button: copy, save to Photos, AirDrop, or send anywhere.
Resizable Colour Palette
Drag from the corner to choose how many swatches are visible.
A softer Correction Pen
Three new softness settings let you choose how gentle or sharp the edge is.
Smoother collection browsing
Browsing your collections is much smoother, and you can tap a collection name to rename it.
Faster, restyled menus and screens
Dock Options, Layer Options and the mini colour picker pop up instantly. Document Setup and Export are restyled so options are easier to find.
Some other little things:
- Updated button icons throughout the app
- Colour swatches now use squircles
- Filled-circle eraser hover indicator
- Top menus hide individually when drawing near them
- The floating selection menu sits above other panels
- The iPhone top menu is split so you see more of the page
4.5.2 20 May
It's pretty cold in Canada where our lead Flow engineer Adam has been rebuilding the Flow drawing engine from the ground up. It's been a mammoth effort but he's emerged with some truly amazing results which will unlock the next generation of Flow features. And right now you get to enjoy the first big thing: a huge new leap in performance.
Questions? Talk to us at flow@bonobolabs.com (we're human).
Here's what's new for you:
- Blazing fast page loading. Pages load so fast now that it's actually taken us a bit of time to get used to it. Is that irony? We aren't entirely sure. The important thing is no more waiting as you move around your document.
- Super responsive drawing. The tools now work even faster than we thought possible. It really does feel like ink is flowing out as fast as you can write and draw.
- Buttery smooth panning. Panning around documents in this new engine is so smooth it's simply a joy.
- Zoom in way, way further. You can now zoom in 10 times further than before.
- More accurate selecting and erasing. The lasso and eraser tools now work much more precisely, so it's easier to draw around or remove just the strokes you want.
- Better drawing resolution. The page now displays at full resolution all the time, so you'll no longer see unsightly changes in resolution as you draw new strokes. This could happen before, especially with tools like the crayon.
- Sharper background patterns. Grids, dots and lines now stay crisp no matter how far in you go.
- Better correction pen. This tool now has a better edge, supports layers, and with Apple Pencil shows a live preview of how it will erase.
The page scrubber has been removed. A new way to see and manage the pages of your documents is coming soon.

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.

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 colour, 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 colours. Drop in images from other apps or tap the Add button in the top menu. Flow will automatically show key colours from the image, which you can tap to use with your current tool or import to your palette.

4.2.0 16/09/2025
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.

• Updated menu bar and unified panel borders

Thank you
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.

4.1.1 15/08/2025
Oh snap, it's a new update for Flow and it's all about making straight lines and perfect shapes. Actually, it's not all about that, there is a bunch of other cool stuff too like a brand new brush tool and updated Tool Designer.
Here's what's new:
- Snap perfect lines and shapes. Flow can now detect what you've just drawn and turn it into a perfect straight line or shape. After drawing a stroke, simply hold still for a brief moment without lifting up. Flow detects straight lines, curved lines, rectangles (including squares), circles, ellipses, and triangles. Nearly straight lines snap to perfectly straight and let you drag the end point around, snapping to horizontal and vertical as you get close. You can even enable a menu that pops up to add arrows and dots to the ends of your lines. Find the preferences in the Drawing and Gestures settings.
- Redesigned ruler. The ruler now comes in two modes: Simple and Technical. The new Simple ruler puts a ruler object on the page that you can drag around, rotate with two fingers, and draw along its edges. Tap the magnet icon to snap rotation to 5 degree increments, or tap the rotation handle to set it perfectly horizontal or vertical. The previous design lives on as Technical mode.
- New Flat Brush tool. Similar to the round brush pen, but with a wide flat brush tip that can be rotated and a more pronounced faded edge.
- Updated Tool Designer. The Tool Setup screen is now the Tool Designer, with a new interface that lets you choose the size, opacity and color to try out on the scratch pad as you fine tune your preferences.
- Better eyedropper. It now does a better job of picking the right color you drag over, with a new setting for grabbing the exact color on the page or the original tool color, and a new one finger press + draw gesture to bring it up.
- New stroke width fluctuation model. Strokes now vary in width organically with a more natural feel that stays consistent at any zoom level, adjustable in the Tool Designer.
- New stroke fade control. Choose how a tool fades in and out as you draw with it, in the Tool Designer.
- New menu for Fun Options. There is a new menu on the main menu just for the fun things. What are the fun things, you ask? Take a look. Got a fun idea to add to Flow? Let us know!
