Data Bases

I do enjoy the simplicity, but I also enjoy the potential usability that can go way beyond simplicity. I presume that the intended to keep it simple which I presume which I would enjoy however there’s something that I need to and it’s about the idea of databases the way I see it is that you could take any one of those cards and within it you could make other cars within it which in itself becomes a database. I’m sure you understand that now I’m sure that it’s important that that database remain. Intact and for some reason that the whole app doesn’t disappear so I know there’s some way of achieving that no another thing is I have been. I have been toying with the idea of creating a let’s call it a a master system of my system within within say ex mind and look at mine and look at that as being like the organizational structure with the top with the top of box being like me and all the other boxes going across being like areas of concerned or areas of my interest and then I’d have a link from each one of those That will be going to one of the databases as I’m calling them or collections within cod, flow plus I just wanna know if that concept would work because what I would need is is probably the way it would work is that I would set something up in the next mind and automatically potentially link or create a database or at least at the top level one within cod, flow I’ll stop there because I’m just wondering if that concept would somehow fit in with your within your company. Thanks for listening.

Real index cards with iPad!

LOVE this app because I was still able to hand write flash cards without wasting paper, and I can dual-screen my notes and the card flow app to make study guides. This is the best study tool ever, and so worth the purchase. I use it every day during nursing school. I do have some suggestions for how to improve the app experience. The first and foremost is that I would like to have a toggle for the eraser size, since currently it is not customizable. I would also like to see a + sign to add more cards from ANY card, not just the last one in the deck. Sometimes I want to organize the cards into different piles, and adding from any of those piles would be easier than having a + button only from the last card. Finally, I would like to see folders to organize entire boards, rather than just labels. This would make it easier to organize boards based on what I use them for. Overall I love this app and will continue to love and use it!

Amazing app closest thing to a real index card and whiteboard you’ll find

This app is amazing. It uses drag and drop to the fullest. Has many boards. Custom names and tags. Little tapes that connect index cards simply by tapping holding and dragging to another card. The tape is my favorite feature. Supports many templates. You can change the color of cards, draw or text on them. You can draw on the board itself. Another amazing feature is the ability to herd your cards together. On the lower left you can pick a formation and it’ll auto sort the cards you have selected into that formation similar to how a band changes formations. Also has smooth flip by two finger pressing. You can change the behavior of when cards flip. You can use this to create agile boards for scrum project managing. You can create character connections for stories or games. It’s awesome for school notes. It runs really smooth and feels like a digital table. All I need now is digital scissors to cut the cards into shapes and it’s game over! Lol. Such an amazing app I can’t compliment it enough. Had to get the pro version because it’s literally that good. I use it on a 6th gen ipad and love it.
