I have hastily tried around 20 different apps in search of a suitable application to perform remote teaching once Covid had forced me out of the classroom. I’m a math professor and needed an application that allowed an unlimited page length. I attempted to get by with others that had other helpful drawing tools, but having to open a new page every couple minutes ultimately made those apps a deal breaker. Now, apples notes was working well, but the inability to save in a format other than its own proprietary file system left me in search of a solution. At this point I discovered Flow which had almost everything that I needed. There is always room for improvement, but the developers seem to be on top of all that while making continual updates as well as creating new features (rulers as of late). I would like to see the ability to draw a strait line without having to open the ruler for that, but this is something users can ask for and the developers appear to listen. That one aspect alone is a huge game changer for me. I’m just not used to using software where the devs listen to the customer/users. All in all, flow and it’s other apps have proved to be absolutely essential for teaching remotely. I could go on and on about how I use the features to create a learning environment that makes the remote learning process much less painless for both me and my students, but I’d suggest give it a try.
Developer Response Hi - thank you so much! It is always nice to hear positive feedback from our customers. Those words definitely motivate us to do better and better. Cheers, Anj

Learn from 53, Flow team. Once upon a time there was an app called Paper, by 53. It failed to improve and progress the way it’s users needed it to and now it’s a piece of crap. You guys are riding a very thin line with having minimal tools and options while still remaining relevant and having a very elegant app that’s a joy to use. As long as apps like Procreate exist, where you only pay once and can be as “pro” or as basic as you want with it, Flow is going to be a challenging sell. You’re riding on brand and aesthetics and that may not carry you forever. But I get the vision of Flow and I personally love it. I’m a graphic designer, so it’s nice having a digital space to draw and think while not worrying about layers or being too granular with my sketches. Flow gives me permission to be messy, and I like that. The paper formats are nice, I’ve found myself using the ruled format from time to time to take notes since Flow has my favorite interface (and sounds!) of any drawing app...so why not? Tools are great, I love the color picker and lack of total freedom while still having a TON of options. I don’t feel restricted with color. I’d be wary with adding much in the way of functionality, but new tools from time to time would be fun. I’m looking forward to the app getting better at what it already does as opposed to becoming more feature-heavy.

I’ve been searching for a drawing program EXACTLY like this for years now. Everything is exactly how I’ve wished drawing programs would be and feels completely natural. I got an iPad hoping to reignite my passion for art but didn’t have much luck because the programs I was using didn’t flow (no pun intended) or feel natural. I felt held back. Switching to Flow has brought everything I loved about art back full-force. It’s easy to use and just feels “right.” For the first time in years I’ve been looking forward to drawing every second of my day- during work all I can think about is how excited I am to draw during break, and after my break, I can hardly wait to get home to keep drawing. Art was such an important thing to me growing up and losing it hit me hard. Flow bringing my enthusiasm back means more to me than I could put into words. **Edit: I originally wrote this saying that I wished layers would be added, but after a few days of usage, I take that back. I’ve quickly adjusted to not using layers (though I will say, I’m used to using 2-3 layers at most, so there wasn’t a huge readjustment I had to go through) and I prefer the program without them. I never noticed before how much layers stall and complicate the process. So, I truly and honestly wouldn’t change anything about Flow. I honestly think it’s the perfect art program.
Developer Response Hi - thank you so much for taking the time to leave us this amazing review! Every bit of feedback like this does so much to help us out. Adding layers is not available yet but this feature is already listed on our feature request board: https://bonobo.canny.io/flow/p/layers. Please add your vote to help bump it up our list and also so that you'll be notified automatically if the status changes. We’re very grateful for customers like you and hope you stick with us for years to come! Regards, Anj

It's pretty cold in Canada where our lead Flow engineer Adam has been bunkered down 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. 10!
- 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 retired. 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.

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.

4.2.0 09/16/2025
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.
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
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.

4.1.0 08/12/2025
Flow 4 is here — our biggest update ever!
Powerful tool upgrades, smarter controls, and thoughtful refinements across every corner of the app. Everything designed to keep you in your creative zone.
Full release notes (including a quick reference for what’s moved) are available inside the app, so make sure you check them out for all the juicy details.
–––
– Quick Menu, Pencil Pro, Barrel Roll
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.

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
3.7.2 04/22/2025
It's pretty cold in Canada where our lead Flow engineer Adam has been bunkered down 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.

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. 10!
- 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 retired. A new way to see and manage the pages of your documents is coming soon.
