iOS: Even if you don't have a panic disorder, sometimes you might worry about stuff that turns out OK in the end. Things aren't always bad as they seem. Worry Watch helps you track what's bothering you and reminds you to log the outcomes.
This password-protected app lets you journal your worries. Once you type in what's bothering you, the app can check in with you later to see how things turned out. Next time you're anxious, the app can run a report so you can see that things may not have been as bad as they seemed at the time.
Tools like this won't replace traditional therapies, but can help enhance them. Always check with a mental health professional if they are treating you for a psychological condition.
