Yes, the P4 does have a built-in web server which will allow you to connect to your WiFi network without having to use a PC. You can use your tablet to search for nearby WiFi networks and connect directly to the P4. From there, you enter the factory assigned IP address of the controller into your web browser and you'll be connected to the P4's web server. The web server at the moment can only be used to configure WiFi settings and WiFi module firmware updates. At a later point, once we complete testing for safety and security, you will be able to have more control over the actual functions of the P4; view sensor and probe data, socket control, feed pauses, maintenance modes, webcam viewing, and much more.
Our GHL Control Center PC software will give you the most complete experience with our products. P4 firmware updates, PAB-device firmware update, backing up controller and probe data, and adding new PAB-devices to the P4 system are all done through GHL Control Center. If you need to get an idea for how our software works,
@reefwiser has some great videos which show helpful tips for using GCC. We also have a Youtube channel with tutorials using GCC.
As far as accessibility goes, you can run GCC either on a Mac using VMware Fusion OR on a PC. Nowadays PC's can be purchased for under $200. I just recently saw a Windows-based RCA tablet for less than $100 at Walmart. It may be worth looking into this one:

You can also create and assign functions using the touch keys on the P4 itself. Reefwiser shared a photo which perfectly shows how our menu is laid out on the P4.

Just to clarify, we did identify with you two bugs in our GCC software that pops up ONLY for those connecting to their Doser 2.1 SA wirelessly. Performing calibration and manually turning on specific pumps via myGHL, app, or USB connection all work just fine. The issue does not affect any other device, only the Doser 2.1 SA. We also mentioned that this issue will be addressed in the next GCC release and to use the app on the meantime if you still wanted wireless access. You can also use myGHL to perform the same tasks. GCC is not the only option for connecting to the doser.
@divewsharks
The PC software becomes necessary if you want to update firmware, get the doser connected to your WiFi network, or setup myGHL. Otherwise, you'll be able to wirelessly control it right out of the box with your phone or tablet.
