Signal is a privacy app that uses end-to-end encryption for individual and group texts, videos, documents, voice, and picture messaging. Open Whisper, Signal's parent company, produced Signal using grants and donations, utilizing Open Source software, with the aim of providing a free and secure platform for worldwide communication, without SMS or MMS fees—this even includes free long-distance calls to anyone, anywhere in the world who also has the Signal app! No one at Signal or anywhere else can read or view communications on the platform, they can only be viewed by the individual user, who can also choose when each message will disappear. Since the whole point of an encrypted communication app is to ensure privacy, Signal is free of tracking, affiliate marketers, and ads. Signal uses your existing address book and phone number, and will only allow you to register one mobile device, so you'll need to choose if you want to use your iPhone or iPad. Getting Signal on your iPhone is free and easy, it pops right up in the App Store, but Signal for iPad is a bit more complicated. Read on to learn how to get Signal on your iPad!

Unfortunately, the official version is tiny; it doesn't fill the iPad screen and leaves a large, black frame around the app. Don't worry, though, we'll go over a trick you can use to get fullscreen Instagram on your iPad
