What Makes NoteDex Different?

"The magic of the notecard format is that it helps you organize one idea, thought or meeting per card'
(Prem Sundaram, Information Management Consultant, Los Angeles)

NoteDex is based on a timeless 'index card' style format creating 'short-form' notes. Unlike 'long-form' note apps like Evernote or OneNote, NoteDex allows you to create single note cards for each piece of information you are capturing. This makes it very efficient to see many cards at once - rather than just a text list of notes - and quickly find the note you are looking for.


Evernote shows your notes one by one in a list with their title and one sentence of text.  This makes it hard to see all your notes at a glance.



NoteDex is unique by using a notecard format and shows a visual grid of notecard previews - making it quick to see all your notes at a glance.



OneNote, like other note apps, also shows your notes one by one in a list on the left - again making it hard to see your notes at a glance.


Long-Form and Short-Form Note Apps

Don't get us wrong - we love Evernote and OneNote. In fact, we encourage using both types of note-taking app in your daily workflow. Long-form note apps are great for rapid capture of your notes or scribbles during a meeting or lecture - when you don't have too much time to think - and then we recommend using NoteDex to summarize your meeting notes into short-form notecards - capturing the various bits of information and insights related to your class, meeting or project.  You can of course also create detailed notes with NoteDex and capture quite a lot of information (and scribbles!) on a notecard using small font - or by scrolling down a card.

But, in summary, the main difference is that unlike long-form note apps the notecards in NoteDex can be easily viewed together to give you a big-picture overview.  This allows for NoteDex to give you a unique and rapid visual access to your notes to find what you are looking for.   Then you can then further organize your notecards using our powerful 'kanban' card organizer (like Trello) where you can move around cards in rows and columns to help you plan, organize, and visualize your notes. Unlike Trello however we have a more powerful 2-D organizing view (something Trello still can't do) - meaning you can have both horizontal swim lanes and vertical columns on the same page to help organize.

For me, Notedex is a handy addition to OneNote. The cards give a clear overview and is a nice tool for research.

How it works

Do Any of These Issues Resonate with You?

Are you looking for a simple app that stores data reliably and privately so you can feel confident and trust your data is secure?

Unlike other apps, you are not the product!  We maintain a private enterprise grade Microsoft Azure cloud and the only one who has access to your data is you.  To fund our operations, we charge you for the app. We do not use or sell your data. NoteDex is a private company and completely self-funded. We have never taken any VC money and the product is 100% owned and funded by Sundaram Applied Technologies. So, your subscription really means a lot! We've also been in business for nearly 10 years, so you don't need to worry if we'll be around tomorrow. The original app, Index Cards for Windows was launched in 2016 and NoteDex was launched early 2020.

Are you looking for a truly cross platform note card app so you can start on your phone and continue on your desktop -on any device?

The developers behind NoteDex worked hard to ensure that the app can work on any device, no matter what kind of operating system or browser you use. This means your index cards are always accessible on all your devices - such as a Microsoft Surface Pro, iPad, or Samsung Galaxy Tablet for instance.  It also means that you can share a stack online to any friend or colleagues, regardless of whether they use a MacOS, Windows or other device.

Do you find that organizing and retrieving notes can be difficult?

The struggle of trying to find that one note you wrote down last week is real! NoteDex was created by an information management consultant, and we know that capturing notes is only half the battle.  It's not useful unless you can easily and quickly retrieve your notes and find those great ideas you captured last week. 

A lot of new tools today seem to forget this.  If you're like us, your notes are everywhere and sometimes it's hard to find that one specific piece of information. That's the problem we found with electronic notebook apps like Evernote and Microsoft OneNote and is why motivated us to build NoteDex.  Looking for an alternative to Evernote?


With NoteDex we've made finding anything easier than ever with our innovative and unique visual thumbnails which allow you rapid access in seeing all your projects or classes as well as recent searches by keyword! We also recently introduced another great feature: The Productivity Sidebar - take a quick note without leaving the app.  Your productivity will thank you later.

Are you looking for Inking capability that is cross platform so you are not stuck on one platform?

NoteDex is the only app that lets you take notes and draw sketches on all your devices. You can, for example, start creating flashcards on an iPad using your Apple Pencil, and then finish it up on your PC with your Surface Pen. Not many other apps can do this. Then you could open those same flashcards on your Android phone to study on the go.  They all work in tandem to provide accurate editing and viewing capabilities on all your devices. We designed NoteDex to look like a real 3 x 5 index card on your screen - a pixel perfect rendition of a real index card.  If you like you can also set a template to have a background of a ruled index card.  NoteDex is so much easier than using Word or Google Docs.

Do you want to share your Cards and Stacks with people easily?

NoteDex features a simple share to web option, where anyone you choose can view (or even edit) the stack that you share with them. Ideal for creating that stack of recipe notecards and sharing with the family (Seriously, we do that!). Not only can you share your favorite recipes, but also keep them protected. You decide who gets access to that digital cooking journal of yours by setting passwords or expiration dates on your precious family recipe cards!

Do you want to study using spaced repetition to memorize better?

Many students use our index cards app for education at school to take class notes, summarize lecture materials, use to take notes when reading, and to create flash cards for study practice.  Whether its for language, science, even art.  We have a Leitner learning based Study Mode where you can review your study cards and answer based on your answer confidence.   Read our article on our blog How to Ace your Studies using Handwritten Digital Flashcards

Are you looking to avoid app subscriptions?

We know that for many people, the thought of entering into and paying a monthly subscription for an app is not appealing. Subscriptions are ultimately better for all of us, since they help developers like us to have the more predictable cashflow to keep developing the app and maintain operating costs. We do offer subscriptions, priced at the cost of a cup of coffee each month. But for now, we are also offering a one-time lifetime deal - to gain traction and support the app at this launch stage.  We have priced our one-time payment lifetime deal quite aggressively during the 7 Day Trial - but this price is likely to go up in the coming months. So take advantage of this special offer!
