To me it seems to take longer coming out of sleep the longer it was in sleep. I use it for my clock at nite and lean over to click it awake to see the time. Tonite will be a first good test.
Should be no prob to uninstall if needed. Anybody fence sitting should just try it for themselves.
Poster in imagio forum states it works on imagio as well. Mine arrives in a couple days. My pocket's gonna lose some weight.Lol.
Edit: The little lagginess coming out of sleep mode seems to have quit. Not sure why the change for the better, but this is nice. Thumbs up for this app.
