Apex and reefkeeper controllers can both be connected to your home wifi or LAN.
I own a Reefkeeper system and it does a bunch of thing it's not just a timer, with a little imagination and the right modules you can make it do practically anything you want. Just an example of how it is more than just a timer, you can connect a temperature probe to the system, and then plug your heater into it, if the heater ever malfunctions (usually always on) it will cut power to the heater and not cook your fish. You can also expand the system to fit you needs with added modules, yes they cost a little bit of cash but I feel with what you can do with this system, if you are into automation, would be well worth the price tag.
I know you can do the same thing with the Apex controller I just don't own that one so cannot say anything about it. They are about the same price range, the Apex seems more user friendly and more flashy, the reefkeeper is plain but works for everything I want it to do.
Here are some links to Apex, Reefkeeper, and to DIY controllers:
ReefKeeper: (Their website is horrible, but if you call them they will spend plenty of time explaining everything)
There are a ton of youtube videos out there with people showing how they built their controller as well.
