I'm currently looking for a Pokedex app that will let me track which letters of Unown I've caught in my Soul Silver save. Could I just use a list and a normal Pokedex app? Yes. However that eliminates a lot of the fun of Pokemon to me. There's a reason Nintendo doesn't just release Pokemon as a text game, we love playing excel spreadsheets but don't want to think about how it's an excel spreadsheet. The visual aspect of Pokemon is actually extremely important.
I would have the poster with the Pokemon to cross off as a kid, but now I have apps. Anybody have any apps with the Unown separated?
