Inkflow 3.6 with iOS7 Support

We’ve just released Inkflow 3.6 to the App Store, re-mastered with a native iOS7 UI and 64-bit support.

Yes, *finally*! :)

Inkflow Re-Mastered

I know a lot of folks have been patiently waiting for this. Why did it take so long? We wanted to be extra-extra careful. Unlike previous iOS updates, iOS 7 was more than just an interface change. It wasn’t a simple matter of just changing a few flags and re-compiling. A number of things had to be re-written just to work the same way.

It’s a non-trivial amount of work, and we had initially considered rolling this out as a paid upgrade. However, in the end we decided to make it a free update for everyone, for a couple of reasons:

1. Some folks really hate paying for updates, and

2. Our loyal customers don’t like big changes, especially loss of functionality.

Both of these are understandable. You guys depend on Inkflow to get your work done, and we want to make sure there are no disruptions.

So, with v3.6 you can expect two things: It’s a free update, and everything should work the same as before.

Of course, “work the same” doesn’t mean it can’t be a bit better:

Interface Improvements

You’ll notice a more streamlined UI with more emphasis on your content. No more plasticky bevels! :) Replaced with understated gray with thin & light icons.


Even the palette is thinner, leaving more room for your canvas.

If you look closely, you’ll notice a few new animations here and there, but we’ve been careful not to go overboard with them (it’s tempting, believe me).

Note that Apple has discontinued support the original iPad 1 for iOS7. However, if you have one, you can still download the previous version with iOS 6 support. Inkflow still runs great, even on the original iPad.

Ok, Go Get It!

If you have auto-updates enabled in the App Store, you might already have the update installed by now. If not, just download it here.

I hope you like this update. Each version is rated separately. If you have a moment, please consider leaving us a rating in the App Store. It really means a lot to us!


Introducing Inkflow 3: With Inkport

by qrayon 22. July 2013 18:49


We built Inkflow to make visual thinking easier, to bring the ease of pen and paper into the iPad age. The thing is, even we still find ourselves using pen and paper a lot. It’s hard to give up our Moleskine notebooks and G2 pens. How can we use both paper and iPad better together?

Inkport: Copy and Paste from the Real World

Inkflow Plus v3 includes a powerful new feature called Inkport. Inkport uses the iPad’s camera to scan high-resolution images of your written notes and instantly converts them into Inkflow’s native vector ink. Once on your iPad, you can edit, rotate, resize and rearrange things as if you had drawn them in Inkflow.

Inkport lets you go from paper to iPad without missing a beat.

Check out this video of Inkport in action:


Think across boundaries. See a shape or pattern in a book you like? Use Inkport to pull it into Inkflow and incorporate it into your designs. Easily combine notes and drawings from different notebooks.

Inkport works well across a variety of handwritten and printed media, and is optimized for dark inks on light colored paper. Like to think in color? No problem, Inkport works with colored inks too.

We’re pretty sure Inkport is going to change the way you use pen and paper in your workflow. What used to require scanning in your notes, then spending minutes tweaking filters in Photoshop can now be done instantly, right on your iPad. Spend more time on your ideas, not on your tools.

More Creature Comforts

Inkflow 3 also includes a slew of interface and feature enhancements that make it even easier to use. You can now directly access your .inkflow files via iTunes. iPad users also get an adjustable wrist guard, and the ability to set text style defaults.

For those of you who have upgraded to Inkflow Plus, thank you so much! In addition to Inkport, we’re adding the ability to rotate photos in Inkflow 3, with a cool new rotation snap feature. Also, by popular request, is a new menu option to flip ink.

Let’s look at these additional features in a little more detail:

iTunes File Sharing

For those of you with a lot of Inkflow books, iTunes File Sharing is a powerful way to manage your files directly. To access your books, open iTunes, select your device, then click on Inkflow in the Apps tab. Each book is stored in it’s own .inkflow file. You can copy these books to your Mac for backing up, or to another iPad, iPhone, or iPod Touch with Inkflow installed.


Tip: You can even access your files wirelessly using WiFi syncing in iTunes.

Wrist Guard (iPad)

A number of you guys have asked for a dedicated wrist guard for the iPad. In Inkflow 3, you’ve now got one. Our design challenge was to add an easy-to-use wrist guard without cluttering up the interface or being too distracting. Here’s what we came up with:

You’ll notice a new faint gray tab at the lower right of your screen. Pull it up to show the wrist guard. Drag it up and down to adjust the wrist guard height. You can also tap on the tab to quickly toggle the wrist guard display.


For folks who don’t want to use the wrist guard, and would prefer a little less on-screen clutter, you can disable it in the settings menu from the Gallery.

Text Defaults (iPad)

Tired of changing from left-aligned 48pt Helvetica Regular? The text editor toolbar has a new option to set the default font style. Set up any combination of font, font-weight, alignment, size, and color you want, then tap on the new Favorite Style button (with the star icon), and select “Set As Default Style”. All newly added text will have this style.

You can also change the currently edited text’s style to match the current default with the second option: “Reset to Default Style”. This is also a handy way to quickly copy the style from one text box to another.


Photo Rotation with Rotation Snap (Inkflow Plus)

We have been planning on adding the ability to rotate photos for a while, but wanted to get the interaction design just right. There are some interesting subtleties about rotating images: You generally want to rotate images at regular, compass-point, increments… Except when you don’t. You also want to be able to straighten images that are slightly off center. We could have added an extra menu option to do this, but thought long and hard about how to combine the two operations. The outcome is, what we think, a unique rotation snap tool:

Rotating images is easy enough, just select one or more images, including ink if you like, and drag the round rotation grip as before. What’s new is that you’ll notice 8 or more round snap guides appear around the circumference of rotation. Dragging near to these guides to snap to the 8 compass points. You can also drag your finger farther away to rotate to an arbitrary angle. Ink and photos now rotate together, so you can easily keep your annotations pinned to your photos when rotating.

If you select an image that has been rotated to an arbitrary angle, you will see an additional snap point that will snap that image back to it’s original, upright rotation. This lets you easily straighten images without an extra piece of UI.


Flip Ink (Inkflow Plus)

Inkflow’s signature selection tool has always allowed you to easily scale and stretch ink. One limitation until now has been you couldn’t create a mirror image of the selected ink. We have actually been thinking long and hard about this. We originally tested the ability to skew ink in reverse, i.e. to stretch it into a mirror image. That is a pretty cool interaction, but the problem is that it takes too much space to snap the image into an exact mirror image.

We finally settled on adding a context menu option to quickly flip ink horizontally in place. To use it, just select some ink, tap on the selection, then select “Flip Ink”:


How about flipping ink vertically? No problem, just flip it horizontally, then use the rotation snap feature to turn it 180 degrees. These two new features work really well together. You can now easily create repeating patterns and tessellation effects of your work.

Making Thinking Just a Little Easier

Inkflow’s goal continues to be the best tool for visual thinking. Even as features like Inkport blur the lines between analog and digital, we have worked hard to capture the freeform essence of writing on paper, but updated for the digital world. What makes writing on paper a wonderful experience is how unrestricted and unencumbered it is. While we continue to add features and adjustments to Inkflow, way beyond what pen and paper can do, we are being very careful not to detract from this kind of experience.

Inkflow Plus v3: Free for All Existing Plus Users

At some point in the future, we will probably have to release a paid upgrade to a new codebase, but for now, we really like providing these major updates for free. It’s a way to thank you guys who have already upgraded.

There’s a raging debate about how independent developers should charge for major updates. The truth is, we go back and forth on this issue a lot. On one hand, the single paid upgrade is simple and clean. No need to worry about buying additional features one-by-one or being “nickel and dimed”. The problem is that it’s hard to keep the lights on if all you do is issue free updates. :) That is, unless your user base keeps growing.

The magic economics of free upgrades work when you genuinely love our Apps and tell other people about them. We really, really appreciate all the tweets and blogs you guys have written. It means a great deal to hear about someone enjoying our Apps, and it really helps us in a real and tangible way. It’s win-win all the way.

So if you enjoy these new upgrades, please consider taking a minute to rate us in the App Store (each version gets a separate rating). Also, please do tell your friends and colleagues about us.

Thanks, and stay creative!

Introducing Inkflow 2.0: Text, Photos, and a Whole Lot More!

Inkflow 2.0 is now live in the App Store! This is a major upgrade, and brings several popularly requested features:

- Text entry via the keyboard

- Insert and layout photos on your pages

- Paper stationery


QuickStart Guide Plus


Text, Photos, and Ink, Working Seamlessly Together

While Inkflow’s primary goal remains to allow expressive writing and drawing with our proprietary ink engine, there are times when its easier to type in text with the keyboard. Likewise, you can now use photos to better capture the essence of an idea, or to more powerfully convey a story.

You can select photos, text, and ink together, and resize them as a group.

Paper StationeryStationery

The default template now gets a subtle paper texture, and you can easily switch the background of your books from the actions menu.

The Plus Edition also includes a tool to create custom backgrounds from your photos. This is great for creating beautiful custom photo stationery. Also, if the built-in stationery choices don’t quite fit your needs, you can make your own: Just create an image using your favorite art program (you can even draw your own stationery with Inkflow), and save it to your iPad’s camera roll.

New Ways to Be Creative

These new features dramatically expands the scope of what you can do and create with Inkflow, without sacrificing any fluidity or ease of use.

Brainstorm in new dimensions, take long notes in class, create beautiful photo journals, even layout and publish PDF booklets.

Inkflow v1.6 Released: iPad Retina Ink

by qrayon 9. January 2013 11:33

Inkflow banner 325x50

We’re pleased to announce that v1.6 of Inkflow and Inkflow Plus are now available in the App Store as a free upgrade for existing users.

This update takes advantage of the iPhone 5’s larger screen and brings retina ink support to the iPad with iOS6. This results in dramatically clearer lines on devices that support it.

Inkflow retina vs regular


Adding retina support to the iPad wasn’t a matter of just flipping a few bits. Supporting the ginormous resolution means dealing with 4x the pixels and memory as before, with the same hardware. We had to engineer a number of performance improvements to maintain the same silky smooth drawing experience you expect. It took a little longer than expected, but we think you will be pleased with the results.

Even if you are using a device without a retina screen, you should notice a few performance improvements as well.

Please Rate

As always, each App version gets a separate rating. if you like the update, please consider taking a moment to rate this version in the App Store. We really appreciate it!

We also love to hear from folks who use our Apps. Please feel free to drop us a line to let us know how you are using Inkflow, or if there’s a particular feature you would like to see in the future.

Announcing Air Sketch 2.0, with PDF projection!

by qrayon 8. October 2010 17:34

AirSketch banner 325x50

We have gotten lots of great feedback from our enthusiastic users over the past few months (thank you and do keep it up!). It’s clear that many people see the potential of the iPad as a powerful presentation tool. The iPad is the perfect size as a personal wireless whiteboard, and it’s even light enough to carry around in front of an audience.

We’ve taken all your feedback into account and are launching a major new version of Air Sketch today.

Air Sketch 2.0 takes presentations to the next level: You can now open multi-page PDF documents in Air Sketch to wirelessly annotate and project them. This works wonderfully with exported PDFs from all major presentation packages, such as PowerPoint and Keynote. Just email the PDFs to yourself, view them in the Mail app, and open them in Air Sketch. You can advance or flip through the pages in the PDF and draw over them, all of this being wirelessly projected as before.

Tip: Tap the page number on the new PDF controls to quickly jump to any page.

PDF prev next controls

You can also send PDF documents to Air Sketch from any App that supports the “open in…” feature, including 3rd party document managers such as Dropbox or Goodreader. Note that Air Sketch works with one PDF file at a time, and doesn’t store or manage PDF files directly.

 open in air sketch


Email Annotated PDFs

When you are done with your presentation, you can even email the complete PDF file with all your annotations right from Air Sketch using the Email as PDF option on the Send-To control. This makes it easy to share your notes with your audience right after a presentation.

email as pdf control

One thing to be aware of is that there appears to be a limit to the size of email attachments on the iPad. We’ve found that documents under around 10MB (or PDF files up to around 75 pages) tend to be sent ok, but sending larger ones may fail. This appears to be an OS limitation and happens in other Apps as well, which we hope will be addressed in a future upgrade.


Full Page Zoom

We’ve added a few more refinements to Air Sketch, including the ability to zoom out to see the whole page: Just pinch with 2 fingers from the default full-screen zoom level.


Switching in and out of PDF Mode

If you are in the middle of presenting a PDF and need to sketch on a blank page, just erase the annotations and background (if there are annotations, you need to tap the erase button twice). You can then return to where you were by tapping on the PDF button:

PDF button

This works the same if you need to load a snapshot, or a background image from the Photo Library.


Other Improvements

Air Sketch 2.0 comes with additional performance improvements, including smoother background image transitions. The short blank page “flash” between background image changes has been greatly reduced. Scrolling large lists of snapshots is now also much smoother.


Free Update for Existing Users

We have decided to release Air Sketch 2.0 as a free update to everyone who has already purchased Air Sketch v1. This is our little way of saying Thank You to all our early adopters. We are very grateful for your continued support! The update should be available in the App Store within 24 hours.


Please Rate this New Version!

If you like these new features, please consider taking a minute to rate this new version in the App Store. Ratings are per version, and your 5-star ratings go a long way towards helping support future free updates. We are committed to building great apps and earning your 5-star reviews.

If you have any questions or run into any issues, please contact us via the support form and we’ll respond as quickly as possible. Also, do keep your feedback and suggestions coming. We do try to answer all our emails in person, and take all of it into account for future releases.

Air Sketch 1.7 has been released!

by qrayon 18. August 2010 10:14

AirSketch banner 325x50

We’ve made a couple of changes to make transitions between background images smoother without an intermediate blank screen on the remote display.

Now tap erase once to erase the drawing layer, and tap again to erase the background image. Also, when setting a new background image, the previous remote sketch is erased only after editing the new one is complete.

Thanks for using Air Sketch!

Air Sketch v1.6 has been released with 2 brand new features!

by qrayon 9. August 2010 19:19
AirSketch banner 325x50

Thank you for all your feedback and great reviews in the App Store! We really appreciate all your support!

We are introducing two brand new features in this update: Zoom/Pan and Send To.

You can now fluidly zoom and pan around your sketches using 2 fingers. The remote image stays the same (full) size. Tip: Write smaller and smoother text while zoomed in. You can also make some fairly detailed drawings or edits using the pencil tool and zooming. Also, the eraser shrinks when zoomed in, allowing finer control.

send icon 

Tap on the new Send To icon to email your sketches as PDF and JPEG images, or save them to the Photo Library. Tip: JPEG images are typically much smaller than PDFs and are recommended for email to others, but PDFs contain the full-quality image.

This release also includes numerous smaller bug fixes, including smoother erasing.

We hope you enjoy these new additions.

Stickyboard 2.0 has been released!

by qrayon 20. May 2010 20:28


This major update includes free-form drawing with the Marker tool, and the ability to email boards as PDF files.

Download it now for FREE from the App Store.
