There are two kind of applications in the App Store: those that help you accomplish tasks for your digital life, and those that help you in the real world. Think about twitter clients and apps to remember the World Cup schedule. Don’t get me started on Twitter clients.
As for the “real world” apps, we could go on talking about them for hours. I swear I saw apps to help women remember their period. There are apps that comes with entire databases of international recipes.
Now, we have a Ruler.
You fire app Ruler and, well…your iPad is now a wooden ruler. You can switch between inches and centimeters, slide your finger on screen to measure stuff, and that’s it. It’s so simple and well realized I feel stupid for not having thought about this myself.
Available at $0.99 in the App Store, you can’t say no this app.
