Endless creative story openers are now at your fingertips with Lyttony, a rather novel opening-sentence-generator for your iPhone & iPad.   Lyttony creates millions of original and thought-provoking story openers, useful for both teachers and students in creative writing classes, authors or writing clubs needing new inspiration, or just quick ideas for daily writing practice. Lyttony is easy to use. It does not require you to choose from confusing topic lists, play 20-questions, or create an on-line account. You are immediately provided ready-to-use opening lines, with no restrictions on their use. Feel free to copy them as-is into your next best-seller, or edit them to your liking.   Ask Lyttony as many times as you want – there's something for everyone. And if you find a great opener, bookmark it or share it with friends. You can always rewind back to your favorite bookmarked lines later.   Lyttony can send you a new line every day, and create customized stories with your name and your favorite color (and more) woven into in the text. Many more features listed here: * Personalized * You can add your own name, type of pet, favorite color, etc. and Lyttony will weave these into its stories for you. * Customized * The Preferences/Settings page lets you choose a favorite color for the story text. * Bookmark & Rewind * Bookmark up to 10 stories, then tap Rewind to choose a bookmarked story from the list and instantly re-display it. This is good for bookmarking/saving and revisiting prior funny ones, or sending the story-code to friends so they can jump to it it too. * Read Stories Aloud * Lyttony can read your stories out loud, whenever you tap the Speaker/Read button, or automatically with each new story. Tap Settings to choose from any of the installed text-to-speech voices. * Daily Dose * Do you want to receive a daily idea without even running the app? There's a setting for that! Just turn on "Daily Notifications", choose an hour of the day to have it delivered, and every day like clockwork, you will get a new story idea! You can read it in place in the notification center, or tap it to have it displayed by Lyttony. * Global-Sync * Turn on Global-Sync mode and tap in to the "global story-cosmos." All Lyttony users around the world can get the same story at the same time, no matter where they live. So if you and somebody in another country both choose "every hour", then all Lyttony apps will dish out identical stories together every hour. Turn on Global-Sync, set the same time-frequency as your friends, and enjoy synchronized story time. * Share * Send your favorites to friends via e-mail or social media, save them to your photos, or copy/paste them into your writing project. * Shake it up * Shaking your iPad or iPhone will automatically generate a new opener. NOTE: iOS only, Macs are not meant to be shaken or stirred. Need some ideas for your next great story, or stuck trying to think of an opening line for a writing assignment, since "It was a dark and stormy night" is already taken? Let Lyttony provide the impetus to wet the quill, unblock the synapses and pour inspiration into your mind.
