Im also a supporter of fishbit (jumped on the kickstarter after missing out on the beta one) and in my opinion this is more worth it to me than an apex. I only run one reef system, thus don't require much expandability.... the biggest selling point to me though is the use of smart phone or tablet over a dinky display screen. With an apex you have to connect to computer, and router, and then even requires game adapter for wireless access, the fishbit will send me alerts via the app if my heater fails, or if pH is off and can shut off or on needed devices to help remedy these things. Is the apex more advanced, absolutely, but I'm not looking for advanced, I'm looking for wireless tank control through my phone without needing to set up static IP addresses, and mess around with my router and 50 feet ethernet cables. I want something that connects directly to my wifi, and allows me to decide which outlets get turned off or on according to certain tank conditions (temp, pH, or salinity). I went with salinity for instance as I run tunze ATO, so now I will have three failsafes for my auto top off, the tunze eye sensor, the backup float switch, and finally if salinity drops fishbit will just shut down power to the tunze all together. Totally worth it in my book (can you tell I'm excited ) :)
