Smartphone is a great thing, but it lacks the convenience of typing and battery life.
Notepad is a great thing too, but it's very inconvenient to insert custom pages, although it would be useful to have a calendar or reference of resistors marking.
PocketMod is a case when the paper meets applications. It looks like a small pocket book with eight pages. With my app you can "install applications" to paper: you can print out Sudoku, shopping list, cheat sheet and anything you want. Initially it was the idea by Chad Adams, but he has abandoned this project. There is an old version of the program to create a PocketMod, but it has several disadvantages: it's no longer receiving updates, there is no possibility of adding your own pages and very limited customization.
But I'm still a fan of this idea. And I want to "Reload" the PocketMod.
So, meet the PocketMod Reloaded - revival of the great paper organizer.
