ForeFlight recently introduced content packs. I will let them give you the details, but in short it is a .zip file that is a custom set of data the user can add to ForeFlight. Recently Fiddler posted a PDF from Kern Valley Airport detailing landing strips available for use. The guide includes public and private strips along with airstrips out of commission or with unknown condition. I took the public airstrips from the PDF (along with Minietta and Amboy) and put it into a ForeFlight content pack. I'm not sure how I feel about adding private landing strips yet, but maybe if there is interest I can add them. I'm by no means taking any credit of any of the info provided, simply presenting it in a different format. Fiddler, if you'd rather I didn't share your info this way, just let me know and I'll delete. This is also not a complete guide to California or SoCal, but it's a good foundation we can build from. It doesn't include any airstrips that are already on the sectional, but we could always add them if there is useful information to add with them.
When you import it into the app it will give you all the airstrips as waypoints, shown below as dark red circles. It's easy to add them to your flight plan and use them to navigate to.
When you click on a waypoint it will give you a quick summary of the GPS coordinates and other relevant information like elevation, runway length and CTAF (if applicable).
It also has a linked PDF for each waypoint. The PDF includes photos, maps, and more detailed information. Pretty much all of these are taken from Fiddler's document. It's easy to add to these, so if you have photos or suggestions, let me know.
The zip file is attached. Download at your own descretion. Don't edit the contents unless you know what you're doing. The format is pretty finicky, it's easy to mess up.
