I've been using MessagEase quite a bit lately.  Real life got in the way and I had to move, leaving me probably about two weeks without a computer (and therefore, keyboard) to practice Dvorak and Colemak on.  It unfortunately set me back by a decent amount, and I was forced to use my cell phone for pretty much everything.  It sucked, but on the bright side I got some pretty decent practice with MessagEase.  I can say, it is actually quite nice to "type" (if you can call it that) on compared to a standard keyboard made into a touchscreen variant.  My speed has improved a decent amount, though I don't know of a good way to test it.  I still would take a real keyboard and screen any day though.

But now, I've got the real computer set up again--and I'll probably barely even use the cell phone for text input any more.

Ironically, when I was stranded without a computer, I saw an article about a new layout for cell phones coming out called Minuum.  It looks like a joke... it's basically just a bar containing the alphabet and other characters, basically in the QWERTY format, and... that's pretty much it.  Its only claim to fame seems to be the small amount of screen space it takes up.  IMO, MessagEase seems to be about as good as it gets so far.  My only problem is that I've noticed that it often performs sluggishly on my phone, sometimes extremely slow, and registers some fast swipes as a press.  But, my phone's a cheap, low-spec one... an LG Optimus V.  You get what you pay for.

From the site:

Respecting your familiarity with the QWERTY keyboard so you don’t have to re-learn the keyboard layout

Yay, another QWERTY claiming to be something new.  The pictures on the site confirm this.

Nah, I remember seeing that multi-touch setting in the options and reading about it, and it even recommended to keep it off if you're not sure that your phone can handle it.  Knowing that my phone is pretty weak, I left it disabled, didn't even mess with it.  I heard of the Hi-Games app for Android, but I'm waiting for it to leave beta and hit the Play store.  I don't really like the official game accompanying MessagEase, I think I uninstalled it after I learned the basics of how to use it.  The problem is, my phone's specs really do suck... I have to uninstall crap so often just to try something new, I lose track of what I have and don't have.  It's annoying because most of the time I want to compare three similar programs; there's no way I can do it effectively because in most cases I can barely even install two at a time.

There's a setting for "minimum drag length" - anything smaller is considered a tap; you may want to set it lower than the default (I did).

Strange that you say it's "slow", it shouldn't be worse than any other Android keyboard that uses taps and drags?

Is this a recommendation from Saied?  Does it use that much resources?  I've never tried without the trace (except for password fields where it's disabled automatically), let's see how much I depend on it...

Won't vibration consume battery if you type a lot?

Wanting to test its performance and my own typing speed, I just re-installed the MessagEase game.  I got 25 WPM. While slow by my physical keyboard standards, IMO that's quite impressive for manual text input on a tiny touchscreen and a few weeks of forced use (other than using it normally, I did not practice for extended periods of time).  I've noticed that for some characters I know the location well enough that I just have to look in that direction just to make sure I hit the correct square... sometime soon maybe I'll be able to use it without labels on the squares.  This actually makes me want to start practicing to get to, say, 30-40 WPM, and be able to use it blank... if only I could get it set as Android's unlock keyboard.  That would be an awesome screen lock.

To me, the slightest hint of vibration is a good feedback option. I dislike audio feedback and don't want to annoy people in the room with it either. Since no feedback is very frustrating, the vibration is the better option for me. I fiddled with it and ended up with a quite low setting, just enough to be felt.

My battery holds through the day, and if it doesn't it's because of games and not of typing. No problem for me then.

Don't listen to pafkata, he's a cyborg but doesn't know it himself. ;)

Yeah, I think my phone runs Gingerbread.  I have looked several times but failed to find a locked-screen keyboard option.

And by the way, sound is vibration.  You can't have vibration without sound. ;) I didn't mess around much with the settings (I prefer audible feedback), but at least the default vibration options made quite a bit of noise.  You'd definitely have to play with those settings to quiet it down if you really want it quiet.

I use vibration for my unlock screen pattern/gesture (allows me to unlock without taking my eyes off the road when using the phone as an audio player while driving), and currently also coupled with text messages from Google Voice.  Helps tell apart the few standard text messages I get (mostly important and/or automated messages) and those I get through my GV number (the majority).  Plus, with phone in holster, the sound can be muffled and the vibration actually helps in that case.  That's about the only vibration I use.

By the way, one thing I noticed right from the start when I began using the keyboard a while back is that the ! and ? locations are awkward.  I swapped the + and ? buttons and IMO it's much better.  I would have probably done it before, but the reprogramming feature is a bit complex and I didn't feel like figuring it out.

Discovered messagease dual-wielding thanks to this thread.  I'd previously thought my speed had been capped (~30wpm with one thumb).  Looking forward to proving myself wrong.

Dual-layout is fine and dandy, but I do wish there was a separate "two-thumb" layout that would take advantage of the extra "tap" buttons available.  Ideally optimized for thumb-alternation, so that it'd have dvorak-inspired cues like vowels all on one side.

I don't think so.  This is how it currently looks to me on the phone:

I'm saying that, if we had a two-thumb layout with different tap-keys on each side, it would cut down on the number of swipe-keys necessary, be better for muscle memory (since there'd be only one way to type any particular letter), and generally be faster.

It's So you think you can type? (doesn't seem to be search-listed).

I already used that size for convenient one-handed typing, taking less space and allowing you to avoid reaching far away.  It may not be quite as accurate, but the cost is minimal.

It doesn't translate so well into two-hands for the reasons I listed above, but I'm hoping (short of exideas optimizing the two-thumbed layout) that I can just get used to it through practice.

Actually... it wouldn't require reworking of the software as such, only a new definition entry. Much like the "Colemakoid" layout would. That entry would have to redefine the 123 part of its layout, so you'd lose the number pad which is probably unacceptable for most people.

More importantly, Exideas don't want to provide a slew of alternative layouts. They've settled on one optimized layout and are having a hard enough time already trying to convince potential users that this one is what they want. Adding a lot of choices to that equation would just make it more obscure – much like how many outsiders get confused by the plethora of Linux distros and options you can choose from. ("Open WHAT with KD-WHATNOW? I just want something that works... please?")

Not sure that a native two-thumb layout would be all that much more effective, really. It's worth a try and I've given it some thought myself, but the fact that ChengWei can two-thumb his way to 84 WPM with the single 3×3 pad (and furthermore, others are following his lead so he's not some freak storm) is reassuring. Now that I've gotten used to it I feel that I can dual-thumb quite nicely on the standard pad (I still use my own Colemakoid modification but I believe that isn't significantly more effective per se ... and I hope it isn't significantly less effective either).
