I have the MyQ app, works great. I can open/close it from anywhere, which is a nice touch, and it lets me know if it's open for more than 15 minutes as well. The three cars in the garage all have little remotes inside them so I only really use the app sparingly, but it's nice to have.
I also have bought the optional accessory to open/close the door using Apple HomeKit, and allow for further automation, but unlike all my other HomeKit accessories, the darn thing has never worked.
