I am looking for an app . . .

Here's the situation.  Over the last 5 weeks, I have spent countless hours in front of my computer, searching for our communication solution.  Reading blogs, joining Facebook groups, sending emails (mostly to strangers), watching YouTube videos, reading review websites, joining groups for speech therapists and AAC specialists, scheduling meetings with sales reps from the big devices companies, etc.  We are looking at designated communication devices, we are looking at iPad apps, we are looking at low tech PECs books----we are open to everything (and probably the best solution will incorporate something high tech and something low tech).

I am literally trying everything that I know how to do. 

But I need your help.

The iPad apps---well, they are slippery.  A moving target, literally, as new apps are released daily and old ones are modified and fine tuned.   I'm learning as fast as I can, but I am 1000% sure that somewhere out there exists a person (or, more likely, several people) who can help to answer my questions and guide me in my app search.

Help me find that person, please.

Spead the link to this blog post to everyone you know who might have helpful input----or to anyone you know who might know someone else who has helpful input.  (I'm thinking SLPs, speech therapists, iPad people, assistive tech people, people who have speech devices, people who use iPads for kids with special needs, teachers at special needs school, augementative and alternative communication people, etc).

Here's what I'm looking for:
-A full speech generating communication app
-The app should make it is for me to model correct grammar ("I want to eat a bagel" instead of "I want bagel" or "I eat bagel")
-The app should make tenses (play, plays, played, playing) clear, accessible choices
-The app should make plurals an easy option
-The app should not be solely text-based.  Maya is only 3.5, she can't read yet.  *It's ok with me if it starts as text based but I can take the time to add in images on the tiles.  I will take the time to do that stuff, as long as it's possible.
-The app should have a QWERTY keyboard section

Does an app like that exist?  Or is one on the horizon?

The bottom line:
I need an app with growth potential.  I don't want a simple app that might be a good fit for a young child.  I want something big, that I can start exposing her to, that will last.  It's not fair to teach her an app, then take it away and teach another one.  I need something that is big that I can model correct grammar with, and that she can start using too.

Other info:
-We have Proloquo2Go, but it seems cumbersome with the folder layout.  "I want to eat a bagel" takes a large amount of manuevering.  Fine for an adult, or older child, but I'm not sure about a young one.
-I'm eyeing TouchChat with WordPower because I like the word prediction---that seems close to what I'm envisioning--but I can't get an answer as to whether I can add images to the text based tiles. 


Please email me: uncommonfeedback@gmail.com with any information that you have---or, to pass along the email addresses of people who might know.  Thank you, thank you, thank you.  Maya thanks you, too.

As always, I'll pass along anything that I learn here, so that anyone who's interested can benefit from the research, too.
