I use the myq app to open my garage door open regularly. The app is slow to open and generally annoying. For example, the whole interface is initially blocked, so you tap to open and it doesn't register the tap, still doesn't register the tap, then finally it does.
I was not aware of there being ads in it, but I just looked, and you are absolutely right, there is an ad at the top. It looks like its for their home security camera.
Based on my experience with the company, I would not purchase additional products from them. Not based on my desire to use home automation or homekit, just on the fact that the app is poor.
The garage door openers themselves, however, which have battery backup and which open quietly and with a gradual slowing near the finish, are pretty decent. Mainly I wish they had a better, faster app, as the garage door is the smart home thing I used most (followed by maybe Rachio).
