HOW SURE ARE WE
Not in any grossing chart, so this comes from ratings growth (2.9 new ratings a month on average since launch): revenue grows with new ratings, more slowly for apps that collect ratings fast. Tested on 418 apps with verified revenue: typically off by about 2 times, and big earners tend to come out low. Countries we don't track (and Google Play in China, which doesn't exist) aren't included, and neither are ads or web payments. Gross revenue before store fees.

★★★★★ * Navigating through notebooks with many pages is a big hassle (there is no quick way to jump to a specific page or to the end - it's not a big deal on small files, but it's really difficult with 100+ page notebooks).
★★★★★ I am not able to get smooth lines/edges when erasing.

Great app overall but it really NEEDS some fixes

This is a great app overall, but it desperately needs some fixes. For example... * There is no confirmation when deleting pages and no undo for deleted pages - they are gone forever if you make a mistake * There is no confirmation when deleting a file (although I was able to search around and find an accidentally deleted file in the recently deleted area of the Files app) * The app doesn't keep your place when the app re-opens (it is very annoying every time to have to find the last file used and navigate to the last page used) * On my device (a mini), the "wide lines" are still way too close. There needs to be a 'super wide' line option to have decent space for writing * App defaults to finger pointer with no option to change the default to the pen (so you can't open the app and start writing immediately) * Unlike their other app, the eraser doesn't seem to offer the option to erase specific colors (I'm NOT referring to deleting all of a specific color, which can be done). This is so disappointing! * Navigating through notebooks with many pages is a big hassle (there is no quick way to jump to a specific page or to the end - it's not a big deal on small files, but it's really difficult with 100+ page notebooks). Not many page icons are shown either (it would be better to show a whole screen of thumbnail icons so we didn't have to do so much scrolling to find the page we need) * No undo for import issues. For example, I accidentally imported a 200+ page PDF and had to delete each of the 200 pages manually since it wouldn't undo the action * To print, you have to remember to export to a pdf and then print. I think there should be an easier way to print * The icon is so dark that it looks like a grayed out app on my screen. Please add some lighter icon options so users can pick an icon that works better for their screens I had to go to their website for help, but I found their help is lacking. For example... * There is supposed to be a way to shade behind ink, but it doesn't work (it shades over everything). Perhaps this can be done, but it is not explained how to do it * It says you can rotate, but the instructions for this feature do not seem to match what is on the screen (there is no round rotation grip) * It says there is a straight-line tool, but I can't find any such tool, even though I can find the other tools * It references the 'gallery', but I can't find any way to get to the gallery (to access the app's settings). The default home screen seems to be the app's files in the Files App with no settings for this app * It references pan mode, but does not make clear what pan mode actually is * Etc. Please consider the suggestions above. If you were to fix these items, I think it would be a 5 star app.

Just a warning

I haven’t used it enough to comment on everything. They make an app called Cardflow+ which I have been using and I love; and thought this Noteflow+ would be a good companion in which to write my Morning Pages. HOWEVER, two days in ago, twenty minutes of thoughts I had written down, about 4 pages, just disappeared after I went away from the app for a moment. So I had to stop using it since I don’t know the cause and can’t trust it to keep my work. I emailed them but have received no response. That is not a good sign. I like the other app, Cardflow+ but I just realized their subscription price of $2.99 per month is far too expensive when you compare it to an app like Morpholio (by the folks at Moleskin) and it’s simple elegance at only $3.99 per year.

Very Glitchy

For a paid app, it is very glitchy to the point that it is mostly unusable. I frequently experience the app crashing suddenly, or closing the file I was working on and saying it was suddenly “deleted remotely”. It is very annoying. I love the app but I’ve had to switch to alternatives because of how often it crashes.

★★★★★Jan 2, 2023
Application stop working

Application worked for a long time and it was really handy. I think a recent iOS update messed something up. All of my docs that I”ve marked up are blank and I can only see what I wrote but not the picture or document in the back ground. I’ve tried to contact support via the link and it always says my email is wrong, I”ve tried three different addresses. Now I’m stuck with a bunch of notes that are useless and no way to export them out.

I worked for an hour on a project. When I tried to format it so that would fit on one page, it completely disappeared and I haven’t been able to find it.

Store description

Noteflow is designed to replace pen and paper. It is a modern digital notebook that lets you get the most out of your iPad or iPhone. Use it for taking notes, annotating PDFs, sketching and doodling, plus a whole lot more: Copy and paste from the real world: Use Inkport gen 2 to snap a picture of a whiteboard or writing and convert it into Noteflow's native vector ink. No special paper needed. Then resize, re-color, or edit as if you wrote it in Noteflow. Create layered drawings without layers: Use the highlighter tool to color and shade behind existing ink. Use Color-Select to separate and edit individual colors. It's a much more fluid and natural editing experience than with layers. Use the straight-line tool with a grid for fast and intuitive wireframes and drafting. Drag-and-drop, cloud-storage, and more: Noteflow natively integrates with iOS's file system and drag-and-drop capabilities. Drop photos and text into Noteflow, and drag your drawings into other apps. Store your files locally or sync with the cloud service of your choice. Make Noteflow a seamless part of your workflow, the way you like. SPACE FOR YOUR IDEAS TO ROAM Our vision for Noteflow is simple: to be digital pen and paper. The magic of pen and paper is in their versatility. They are useful for so many things, but particularly for the freeform capture of ideas. Noteflow expands upon this quality. You can naturally do all the things you normally do with pen and paper: take notes in meetings or class, and jot down flashes of inspirations on the go. And you can take that to a whole new level: One of Noteflow’s best uses is for "thinking on digital paper": quickly capture key ideas and concepts, then move and organize them on the screen. Noteflow's vector ink engine lets you scale and edit your work without any loss of quality. Your words and drawings remain tack sharp when zoomed in, giving you a huge effective working canvas even on a single page. There are analogues in the physical world, such as sketchnotes or everyday working on a white board, but being able to fluidly edit and move your ideas around the page is something you can only do digitally. When you represent the ideas in your head with your own personal scribbles on the screen, it effectively becomes an extension of your mind - giving you more room to think. We've designed every part of Noteflow to let you intuitively capture and work on your ideas the way you like. Whether it's dropping in existing information, quickly sketching concepts, or assembling polished presentations for others. By resizing ink and zooming in, you have a huge effective canvas to work with, even on a single page. As your ideas shape up, Noteflow has all the tools you need to tidy them up and format them to share with others. DIGITAL TOOLS FOR A DIGITAL AGE I hope you'll find Noteflow a useful part of your workflow, and that you'll discover new ways to do things with it that weren't easy before. We're very proud of the work we've put into Noteflow, but we're also just seen the beginning of what's possible with powerful new digital platforms like the iPad. Our goal is to push these platforms to their limits to craft useful tools. Tools that can help us think a little more clearly, communicate a bit more effectively, and connect with other in new and enriching ways. Thanks for joining us on this journey! -- The App Makers @ Qrayon.
