Check out these 13 paid iOS apps that are now free for a limited time

You can save yourself $2.99 by installing Quick Drafts for free. This is a notepad that turns your reminders into to-do lists, or you can mail them to your email inbox, or post them on your calendar. Usually 99 cents, Wi-Fi Scanner sounds like it will scan the airwaves to find a Wi-Fi signal for your phone. Nope. While the app will hook you up to a Wi-Fi signal faster, it does so by allowing you to scan and paste impossibly long and complex passwords so that you can quickly access a Wi-Fi network. StarNote, usually 99 cents, is now free. It allows you to put your notes together to make your own knowledge system.
Stress and Anxiety Companion teaches you breathing, muscle relaxing and brain exercises, all designed to take your anxiety down. It also is more relaxing to know that you're not paying the usual price of $4.99 for the app! UnicodeConverter, normally 99 cents, turns Unicode into emoji symbols, and vice versa. DreamZ allows you to control your dreams by tracking your movements while you're sleeping. An algorithm helps figure out where you are in the sleep cycle, and when you are in REM sleep (rapid eye movement) the app plays certain audio cues. You will know that you are inside a dream, yet at the same time you can control what is taking place in it. This app is usually $4.99, but is free at the moment.
SOS is a useful app that sends out messages to get you help if necessary. Press a button and a siren goes off. Press another button, and your coordinates are sent to previously chosen contacts. You can also send out the alert without the siren if that is safer. SOS is currently free, but is usually $1.99. The advantage to using the app is that you don't have to waste your battery by using full-time location sharing.
The last freebie we have for you now is Translate Safari 2. Priced normally at $4.99, this app is actually a Safari extension that will translate and read an entire web page aloud. It knows 40+ languages from Bing Translate and 60+ from Google Translate.
Remember, these apps are free for a limited time only. Scoop up the ones you want now before it is too late to get them at no charge!
