Amazing concept but needs improvement

I have been using the app for a couple months now and it definitely has changed my studying for the better.. there’s no way I could’ve handwritten all the notecards I have typed up. However.. the more notecards I accumulate, the more issues I have.. I always type them up on my computer and it seems to be freezing up a lot now. Which is very frustrating when you’re trying to hurry so you can study for a big exam. Also I’ve been trying to open the app on my phone so I can study my cards while I’m putting my son to sleep and the app just keeps giving me a blank white screen. That’s very inconvenient and annoying. I’m really quite sad because I thought this was going to be life changing.. now I am wondering if it was too good to be true :(

Hi! Oh no, we don't want to be too good to be true! Really appreciate the kind words and the good feedback. Hm. I assume you are using the Mac app. How many cards do you have in each stack? We can check if there is any issue here - I have stacks with hundreds of cards and see no problem but it would help to know. On the phone, the app also should be fine but perhaps it is still downloading data? If you could please contact us at we would love to help you work through and fix the issues. Thanks, Prem

I use it my way.

For many years I have used a variety of Notes programs. Most of them were quite good, but they all seemed to be developed for a specific use; for example, taking notes in class, jotting down ideas, or developing lists. One of the problems I have is putting my notes into several different lists, depending on what I had available at the time. As a result, I had a lot of information that I couldn't easily retrieve. NoteDex allows you to move any card to another stack quickly and seamlessly. I also like the freedom to set up the index cards any way I like to fit my needs. On the other notes programs I ended up fitting my needs into the app. The fact that this is a multi-platform app that synchronizes between operating systems, which is important to me as I operate between windows and apple, as well as on the web. Overall, I like the freedom to set up NoteDex in ways that work well for me.

Buggy, not worth it

I recently went back to school to get a BA and was looking for a note taking app that could sync between my iPad Pro, MacBook Air, and google pixel, and that would allow me to use my Apple Pencil to write written notes. That request is a tall order, so I was excited when I stumbled upon Notdex. Unfortunately, this app is too good to be true. It is slow, it lags, and the hand writing functionality is barely usable because of how laggy it is. I had to close the app out and open it back up three times trying to write one note card because the darn thing kept freezing. Additionally, the UI is clunky and the graphics low quality. If the developer is able to address these concerns, thus app would be stellar and absolutely worth the cost. As it stands, though, I would pass on this one.
