4IN is a notepad app supporting handwriting input. Files for scheduling, action, address, and notes are preinstalled in advance. It has been confirmed that this app also works on IOS7.
There are many notepad apps for the iPad and iPhone and they are certainly alright, but we feel they cannot really compete to the user-friendliness that comes with writing with a pen on paper. That is where 4IN comes in, being the greatest rival of paper notepads and aspiring to transcend them by setting the goal of implementing this easy-to-use feature.
Well, then - what do you think makes a paper notepad so easy to use? A lot of things will certainly come to mind, but first of all it’s the flexibility that comes with the option of writing on the margins, now isn’t it? Let’s try something: Just take out your normal notepad that you have around and turn some pages: Around the addresses and your plans, don’t you have corrections and additional information written all over it? Depending on your situation, you might even find some pages with stickers added to when you did not manage to write it down completely. Isn’t the option of adding information like that afterwards the most important feature? Just in the same way, we have implemented an option of free handwriting input. Fortunately, due to the positive evaluation of the handwriting input in our previous work “ThinkWriter”, and by combining data from schedules action and address files we have succeeded in providing a completely new way to use this.
For example, you can link an “address” to your standard address app and add some additional information by writing it by hand. “Action” does not just mean things that you have yet to do, but also encompasses details on your progress and has the value of recording it even after certain tasks have been completed. You can reorganize things you have written in your “schedule”, this is even something you cannot do with a paper notepad. You can display your daily plans or display them for monthly periods. You can take your “Notes” quickly, and even add information tags to them so you can find the necessary page later.

  • Has potential

    by Loren K Richter

    This app needs a little more work to polish it off but overall really great idea for written schedules, actions, contacts and memos. The app crashed when a went to the addresses after importing my address book on a few occasions. When I was able to see the address info without it crashing it seemed very disorganized and missing entries. Conceptually very good but needs some work.

  • Great App!

    by wawright62

    Simple to use, a powerhouse for function. I'm very pleased with this productivity app, it was nice to be able to delete other apps and have everything in one app!

  • Ok

    by Stepwild

    Be great if could use to sign documents and sync to other apps and services, like box or Dropbox.

  • Pretty Good

    by talifer

    The input recognition is a bit slow, resulting in overly jagged, angular letters. But this is on iPhone 4 using os7, so sometimes things are slower than they should be. Worth a try, at any rate.

  • Kudos

    by Mzk.fyre

    Clean design. Good functionality. Great when handwriting notes in multiple languages (Chinese & English for me). Not 5 stars due to inability to sync with Google calendar; although I'm not sure how it would be possible for two way sync with handwritten notes. Overall, very good as a standalone app.

  • Very interesting concept

    by hiroshi.rio

    The app concept is very interesting. With a super clean design it creates a real calendar notes feeling. Zoom works great, hand notes has good options, as color and size, scroll with two fingers makes the work easy. Very well made app indeed. Recommended.

  • Wow

    by glenntex

    Either my handwriting is not suitable for this app, or this app is not suitable for life.

  • Crashed and no sync with calendar

    by Lemonpol

    Great concept, but it crashed three times within my first trial. The calendar is not linked to the ipad calendar, so I would need double book-keeping. Deleted
