I never have a Twitter app crash in the middle of a Tweet. That wouldn't be too terrible to deal with. No, for me, it seems my e-mail application decides to crash after I've spent 20 minutes thumbing out a reply while sitting in a crowded airport. If you've ever lost a love letter, term paper, shopping list or world-class Facebook post, Type Machine is the perfect app for you.

It costs $1.99 in the Google Play Store, and automatically keeps track of the last text typed in every native Android application. It has some great features that satisfy even the most privacy-concerned individuals:

• No unnecessary permissions.

• Supports a PIN number to lock typing history.

• Apps can be blacklisted so no input is recorded.

• History is pruned automatically.

• Password fields are never recorded.

The best part about Type Machine is that it works automatically in the background, and you never need to think about it—until you do.

I'll admit, the thought of installing a keystroke logger on my own device was a little creepy at first. I've never read the "this app requires these permissions" screen more carefully than when installing Type Machine. That said, I've had it only a couple days, and I've already used it to retrieve a Twitter update that got lost amid a program crash. If you have a particularly crash-prone phone, or if you just prefer not to risk the possibility of a lost e-mail, check out Type Machine in the Google Play store.
