Appointment Booking Calendar

How well this listing is tuned to rank in WordPress.org search, on the factors an owner controls. Not popularity, optimization.

Directory rank vs rivals

wp.org popularity rank over time · higher is better · when a rival's line climbs above yours, they've overtaken you

How often this plugin actually ships. A steady rhythm is the maintenance signal a single "last updated" date can't show.

Share of active installs on each version of this plugin · 53% run the current release. Green is the current release; a big slice on older versions is a user base that has stopped updating.

Refined from the date this plugin crossed into its current band.

No paid tier is visible, so we don't put a figure on revenue or sale value: that would be guessing. The install base is a real asset to an acquirer, just not one public data lets us price. A small install base leaves thin data to model from.

   I have been using this plugin for several years now to manage bookings for my photo appointments, and I am still very impressed by its wide range of features. Despite offering so many options, the plugin remains clear, user-friendly, and easy to use. It includes everything I need, including PayPal payment functionality. I would also especially like to highlight the excellent support: responses are very quick, and the help provided is truly first-class. Thank you very much for this great plugin!

   I am new to it so I am still in discovery mode but the page created with booking calendar is working as I was expecting. Need to dig a little bit for multiple booking in the same time slot though.

   It’s pretty good although it’s not easy to learn.

   I’m leaving a review because I got a notification to do so, but nobody has used it on my site yet. I will give actual feedback when it is being used.

   It worked perfectly out of the box. Once I decided I wanted to modify the look of the free version, I contacted support, and they actually guided me through the process. It’s a great plugin with amazingly fast and competent support.
