I’ve spent more time than I care to admit searching for a good keyboard app in the App Store, and I’ve tried a lot of them. This one never surfaced for me in any of my usual searches, which is a shame (likely more on Apple’s search than on you).
I really like the T9-style approach, and I appreciate the clean App Privacy section and straightforward privacy policy.
It needs a little tlc to align with the latest iOS update changes, but my time is too limited at the moment.
