Almost perfect

I like the larger keys, the cursor keys, and text prediction. However, it would be better if we could adjust the size of the keys. I need even larger keys, especially when I type fast. Also, if you could add a row of number keys at the top, then the keyboard would be perfect. Thank you.

A Great Amount of Potential

There is something about this keyboard that just works. Plain and simple. The triangular key lay-out gives a comfortable amount of typing room, and for the most part feels seamless and intuitive. The visual keypad response and key click sounds are a nice touch and not too distracting. I think that implementing haptic-feedback into this keyboard would give it an amazing level of immersion and stand out from all other keyboards *hint hint ;)*

One issue with the current build of the app is the autocorrect. From my experience it consistently prepends extra letters to words and the only fix I've been able to work out is turning off all correct all together.

Overall great start!

Not quite there for me

I use an 8+ iphone
Used the app for about a month now..
apostrophe is on second page so it's very anoying to have to stop and change page to get apostrophe, then change page back to resume typing.
Spell check helps but lacks some basics like: second letter suggestion being an apostrophe.
I also often find an n where the space bar was selected and an r where t was selected. The last are my personal finger issues, but thats (yes, apostrophe is missing) why I needed an alternative to Apples small keyboard.
