Just tried it and really enjoyed, but the contact sources just don’t seem to work? Two options, one from sms and one from com.android.contacts, and neither are correct (missing / duplicate contacts). Confused as to why the dialer can’t just pull from my contacts like every other dialer, or I’d probably switch!
My bad, v tired when I replied. That is an interesting feature the only similar solution I can think of is using something like Fossify Dialer (a fork of the now ad-ridden and proprietary Simple Dialer) and use T9 dialing. That could achieve a similar speed / memorization as a gesture.
You could definitely get good enough at T9 to at least call people without looking at the screen.
