About this app

Flexpansion's advanced word prediction dramatically increases your typing speed in ALL apps. Type using abbreviations, like a txt msg, and Flexpansion 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 abbreviation styles. For example:
* wd → would
* xprc → experience
* tfon → telephone
* 2mrw → tomorrow

No need to memorize anything. No need to pre-define abbreviations. Our Flexible Text Expansion engine deals with whatever you type and learns rapidly from your usage.

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 its suggestions.
* … 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 of text.
* … is derived from the founder's PhD research at Edinburgh University.
* … as well as helping you type faster, may even improve your spelling!

Other features:
* Split 'thumb' keyboard for wider screens
* Arrow keys
* 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 (free), Gingerbread (free), Festive (free), Typewriter, Computer, Red, Blue, Green, Pink.
* Switchable sound themes: Android (free), Festive (free), Mechanical (free), 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.
* Caps Lock, then swipe to move up/down/left/right in text.
 * Option to remove keypress popups.

* Learn from Gmail (BETA) and ANYTHING pasted in.

Try out the variety of sounds in each theme - turn your phone into an old-fashioned typewriter complete with dinging carriage return, play a set of party sounds, or a drum kit while you type!

Available languages:
* English (US or UK)
* German (QWERTZ layout available)
* Spanish (prediction only, no UI)
* Coming soon: French
* If you'd like to be a pre-release tester for a new language, or want your language added, please contact us!

A system message on installation states this app could collect personal data. Rest assured your language data is only stored on your device, never sent across the Internet. We will 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".

The best thing about Flexpansion is its prediction. For years I've dreamnt about having prediction that would predict ONLY WORDS I'VE USED. Thought I'd never ever find that feature. Some users (me for eg) would pay double digits just for that feature alone. Flexpansion won't even predict the words "and" or "the" unless I've used them (you have to select "none" in language settings). I really liked AI PLUS keyboard, but their prediction disintegrates into nonsense much of the time.

I NEED split keyboard. This HAS it and it works well. Customization options are good and relevant. Keyboard height, button size, number row etc. All available and does what it's meant to do. Prediction text seems accurate and quick. Compared to other keyboard apps this has everything apart from I cannot appear to select, highlight, copy, paste text. If this feature can be added asap it would be very helpful. PLEASE add horizontal width control. Split keyboard great but not wide enough.

Hi, thx for your review, very pleased you like it. We just released an update improving prediction. We've had a few requests for highlight/copy/paste etc. Altho the Android UI offers them, we know you only get precision using arrow keys + Highlight etc. We will add that & key width adjustment when we can. - Tim, CEO

Really in two minds about this app. As a text expander it works fine but there are a few oddities which prevent 5 stars, namely putting a space after a period/decimal point (annoying when writing decimal numbers, having to backspace after every decimal) and not being able to edit expansions (need to delete and re-create), and no Search function. Also, text expansions which start with an uncapitalized letter are automatically capitalized. Small annoyances which should be avoidable.

Hi, thanks for your comments. Sorry for annoying issues - we're aware but don't currently have resources to release fixes. You can force lowercase in words which have both upper and lower versions, by pressing long-press after typing the full word (though you won't be able to use correction or completion in that particular instance, as a result).

What's new

* Improved prediction
* Improved capitalisation handling
* Updated user interface style
