I am too. Basically I'll keep it until TMo forces me onto another plan. But Sprint seems to moving to tighten the screws. I'm sure they'd like to get the stragglers off and onto one of the silly unlimited plans.
This works for me, and has for a while. It even restores your database of logged sites. The data is only backed up at night (or while idle at least), while charging (and maybe at 100%?), and on wifi, so if those conditions weren't met since you installed the app and configured your settings, then they likely haven't had a chance to backup yet.
That being said, I have heard others say it didn't restore onto a new device. But this sounds like a Google issue rather than a Signal Check issue.
I’m interested to see how this whole thing pans out because there is still sad chance that the merger maybe kiboshed so let’s see what happens if it takes more than a year I wouldn’t be surprised due to the scale of this merger.
