Voice Dream Writer helps everyone write better: Text-to-speech proofreading reduces mistakes, phonetic and meaning search help you use the right words, and an active outline helps you organize and improve the structure of your writing. • Featured in the US App Store Education Collection. • "Voice Dream Writer's technically designed for people with reading disabilities, but it's useful for just about anyone who needs a little help proofing." - Lifehacker Text-To-Speech Proofreading. Professional proofreaders recommend reading out loud as the best way to catch mistakes. Like a personal proofreader, Voice Dream Writer reads your writing using text-to-speech, so you can easily spot awkward sentences, grammatical errors and typos. Also, it can read words and sentences as you type or voice dictate. This way, you can type faster because you no longer have to look up to check the text you just wrote. Word Finder. Voice Dream Writer helps you find the right words using phonetic search and meaning search. For example, search for "inuf" phonetically, and you will find "enough", and search for "Fast Africa Cat" by meaning and you will find "Cheetah." Word Finder also shows you the dictionary definition of a word as you type without you having to select anything or open another program. Outline. As you write, Voice Dream Writer automatically creates an outline of headings, paragraphs and sentences. The Outline helps you structure your document better by giving you an always-on overview. You can also quickly navigate to a section in a long document without endless scrolling. Finally, you can drag and drop elements in the Outline to organize your writing. No more selecting, cutting and pasting large blocks of text. Besides these unique features, Voice Dream Writer also comes with everything you would expect from any great writing tool: • Comprehensive settings for text appearance • Uncluttered writing area • Search for text • Search for misspelled words • Word count • Synchronize and backup with iCloud • Import and export for Dropbox, Google Drive, and Box • Preview and print with multiple themes • Markdown support for formatting • Export to Microsoft Word format (compatible with Apple Pages) • Support for Bluetooth keyboard The app is not only fully accessible, it was designed with students and adults with print disabilities in mind. There are special tools for VoiceOver users to manage the cursor, select text, and find and correct misspelled words by stepping through them. Voice-based Proofreading and Phonetic Search are invaluable for people with dyslexia. Also included is the research-proven Dyslexie font. Voice Dream Writer will continue to evolve. We would love to hear from you!

This app solves linear equations step by step and plots the result. All the performed calculations are stored in the history. Just enter m, n or two coordinate points and the equation is solved. The final solution can be shared. [ What you get ] - solving logic for different inputs like: - two points - one point and slope - one point and intersection with axis of ordinates - linear equation and x coordinate - linear equation and y coordinate - the input supports decimals and fractions - plot of the result - history function that keeps your given inputs - full solution shown in all necessary steps - no ads! [ How to use ] - there are 6 fields where you can insert any value with a modified keyboard - m for the slope - n for the intersection with the axis of ordinates - x1, y1 and x2, y2 as coordinates for the points - if you enter 3 or 4 values (depending on the calculation you need) and hit the calculate button, the app switches to the solution page - when you hit the calculate button without giving enough values, the app marks it as yellow - when you hit the calculate button with giving invalid values, the app marks it as red - you can tap and/or swipe to get to the solution or history page - the history entries can be deleted or put in order manually - if you click on one history entry, the app will load it to the inputs - you can delete all history entries by using a button
