Thumbly is an iPhone keyboard designed to be used with one hand. Standard mobile keyboards are awkward to use, requiring two thumbs to reach all the keys and involve uncomfortable thumb gymnastics. Thumbly's keys are ergonomically arranged and are easily reached with one thumb using a comfortable side-to-side motion.

Note: Currently only supports the ENGLISH language.

Additional features:
- Swipe to delete, return, shift and capslock.
- Suggests the next word you will type based on what you have already typed.
- Allows you to select between left handed and right handed versions of the keyboard via a button "toggle" press.
- Misspelled words are automatically corrected.
- Unknown words appear in quotes as a suggestion. Selecting this suggestion causes the word to be recorded for the future use of the spell checker.
- Easily accessible list of curated emoji.
- Disable autocorrect at will.

I don't see one. Is it there?

Backspace is achieved by swiping back along the curve of the keyboard. Please see the “Usage” section in the Thumbly app or visit the website for more details. Thanks for the feedback:)

Not word flow

This did does not do the swipe to text feature and merely shifts the keys to repute type. I'm sure that this is sufficient for a good number of people but if you were hoping for a proper replacement to the now defunct word flow keyboard as I was, this is not it. Have it four stars because it never claimed to be a replacement for it, but the swipe features seem strange if they're trying to save space in the keyboard when it already takes so much of the screen.

Old school spacing ,

Amazingly compact

Some clever features. But why add a second period if I double-space after the end of a sentence?. See? Why no semicolon? I agree with the review requesting space around the edges.


I'm reusing this app for the first time in a while. I am transcribing, and this saves so much wear and tear on my wrists. I can type one-handed, and control replay of audio with my other hand. Economy of movement.

I agree I need to avoid typing multiple periods when you space multiple times. This is on the short list of things I need to fix :) The semicolon can be typed by long pressing the ":" button in the number section. Thanks so much for giving me the feedback!
