ListBook ($0.99) by noidentity gmbh is a simple and beautiful list app for your iPhone.
I know that the App Store is cluttered with plenty of list and to-do apps out there. But sometimes there are still gems to be found, and I believe that Listbook is one of them.
From the makers of the nice little financial app called MoneyBook, ListBook is a simple yet beautiful and minimally designed list app for your device.
The interface is fairly straightforward to the new user. On initial launch, you'll see a blank list called "New List." The first thing that came to my mind is "I want to change the name of that list." To do this, you'll notice a button at the bottom right corner that resembles the one in mobile Safari. Tapping this button will take you to a cards view, just like in Safari.
A tab along the bottom of the centered card will show "Settings," and there will be two options: Name and Show Badge. Additionally, if you want to get rid of a list, a delete button is there as well. This is the screen to go to if you want to create a new list.
Each list that you create will be kept separate and you can navigate between them by going to this card view. It's a welcome interface since it so closely resembles mobile Safari in terms of switching windows.
When you view a particular list, you'll see the list name at the top and the traditional Edit and + buttons to the left and right of the name, respectively.
When you add a new item to a list, you'll be taken to a screen that resembles a piece of paper from a day planner or the like. Whatever you need the item to be, just start typing. The first line will appear as the main item in the list screen, and anything after a line break (return) will appear as subtext in the list view.
All items in a list will have a circle to mark off when complete. Completed items will be shown with a green circle with a check mark inside it. It's easy to tell apart the complete and incomplete items of your lists, but if you prefer to filter out the old stuff, there's a toggle for that in the bottom left corner. Swipe to delete is present as well.
Overall, ListBook is a beautiful and minimal list app manager. However, there could be some improvements made. The biggest one, I think, is some sort of method for syncing, preferably with Dropbox. Since it seems that these lists are just plain text, it would be nice to have a syncing solution so that not all your data is just in the app itself, and can be accessed anywhere.
While the card view for different lists is nice, and definitely feels native to iOS, it can be a bit of an annoyance if you have to constantly flick between lists throughout the day. I think having a regular "list" view of your lists would be a nice option to have. But it's not a big deal if you don't keep dozens of lists around.
Support for landscape mode would be a nice bonus, but not necessary.
For what it's worth, ListBook is definitely worth a dollar if you are looking for a well designed and intuitive list app. Definitely worth checking out. It's what I'd expect from the fine makers of MoneyBook.
