Description

From the listing uploaded by “appupdater”.

All Pro features are now unlocked and FREE! Flexpansion's advanced word prediction dramatically increases typing speed in ALL apps. Use 'txt msg spk' abbreviations, and it automatically expands into full, correctly-spelled text. Flexpansion provides everything you'd expect from a predictive text system, including fully-adaptive word completion, next word prediction, editable user dictionary and autocorrect. But also, our unique "Abbreviation expansion" mode understands all common styles. For example: * wd → would * xprc → experience * tfon → telephone * 2mrw → tomorrow No need to memorize or pre-define anything. Our Flexible Text Expansion engine deals with whatever you type and learns rapidly from use. NEW - choose empty base language, then learn from text, to type in ONLY your own words. Add Shakespeare, technical writing, or another language. Flexpansion … * … has an advanced predictive text engine which learns your personal style and continuously improves. * … is compatible with phones, tablets, and hardware keyboards. * … is easily personalized by adding your own abbreviations, words and even whole phrases. For instance set 'qq' (or anything you like) to insert your signature, phone number, or another frequently-typed block. * … is derived from the founder's PhD in AI & Natural Language Processing at Edinburgh University. Other features: * Split 'thumb' option for wider screens * Arrow keys (optional) * Long-press and swipe for punctuation, numbers, or accented letters * Long-press Enter for smileys * Long-press Space to enter input unaltered and learn it  * Long-press ?123 for speech (if supported by device, needs internet) * Switchable visual themes or skins: Donut, Gingerbread, Festive, Typewriter, Computer, Red, Blue, Green, Pink. * Switchable sound themes: Android, Festive, Mechanical, Electric, Model M, Drums, Beep. * Swipe left on the keyboard to undo an expansion, or delete the previous word. Swipe right to redo. * Swipe down to disable prediction, up to force-enable. * Swipe down again to hide the keyboard, tap a text box to bring it back.  * Option to remove keypress popups. * Learn from ANYTHING pasted in. Try out the sounds - turn your phone into an old-fashioned typewriter complete with dinging carriage return, play party sounds, or a drum kit... Available languages: * English (US or UK) * German (QWERTZ layout option) * Spanish (prediction only, no UI) * French (beta) A system message on installation states this app could collect personal data. Rest assured your data is only ever stored on your device, and never leaves it (you can back up/transfer it yourself). We never record typing in password boxes. We are a responsible company, with academic and government support, which you can verify by searching for "Flexpansion Edinburgh University". After activating Flexpansion, to switch between it and other input methods, long-press any text box (Android 2), or swipe down the status bar (Android 3+), then choose "Select Input Method". We think you will love how rapidly Flexpansion adapts to your writing style - check out our great reviews. Please rate us! Although all features are now free, if you find our app useful, please support us by buying Flexpansion Pro (doesn't add anything, but thanks us!) ----- Known issues, which we are working on (see our website for more info): * We don't learn the first word in a sentence. * Still learning some junk , e.g. typos & too many capitals. * Some apps block prediction, and won't let us over-ride. Please contact us AND them! * Miss some keystrokes on some devices. * We know the visuals & sounds need updating! We've focused on functionality. If you have any problems or feature requests, please contact us via our website. We're a small company and will do our best. Thanks for your patience!
