Biggest opportunity: Swap “appointments”, “scheduling” and “calendar” for “bookings”, “direct booking” and “calendars”. “appointments” isn't earning its slot: you're not in the first 24 results for its own search. “bookings” sits at #11 untagged, close enough for a declared tag to move it up. “scheduling” isn't earning its slot: you're not in the first 24 results for its own search. “direct booking” sits at #14 untagged, close enough for a declared tag to move it up. “calendar” isn't earning its slot: it only gets you to #24. “calendars” sits at #17 untagged, close enough for a declared tag to move it up. All five slots are taken, so one has to go.

How it's measured →14%
of downloads still active
At least 30K of 213.4K lifetime downloads are still running, above its category: the median Booking & Events plugin keeps 0.8%, across 940 plugins.
Downloads count every update, not just first installs, so older and more frequently released plugins read lower. Compare against other Booking & Events plugins, not across the directory. wp.org reports active installs as the bottom of a band, so the real rate is this or higher.
This plugin shipped 2 releases in the last 12 months, and every existing install that updated counted as another download. wp.org publishes no split between first installs and updates, so we show the raw rate rather than guess at one.

Reviewer account pattern
from wp.org reviewer profiles8 of the last 13 four- and five-star reviews came from accounts created within a month of posting the review, and 8 of those landed between 2024-07-08 and 2024-07-16.
Registering a wp.org account just to leave a review is common and often entirely legitimate. The share here is unusually high for the sample, so it's worth keeping in mind while reading the reviews.

Had some trouble getting it to work, but yet again Really Simple Plugins support was amazing. A bit harder to reach this time around, but a fix is a fix! This topic was modified 7 months, 3 weeks ago by defotohoeve.

I have a Client whose website uses the SimplyBook system and plugin and when updating to the latest version (luckily on a staging site!!), the plugin crashed the site and had to be disabled. Jarno was great in getting back to me quickly regarding the issue and, provided a pretty straightforward solution, which I tested on the staging site before implementing it on the my Client’s live site. Brilliant support and a good plugin for purpose.

Completely unprofessional support that makes excuses and does not solve the plugin problem. The plugin logs out on its own, notification emails are not delivered. We are losing money and reputation because the demo is displayed after logging out.

The booking system is easy to integrate into the website and offers a wide range of options for customization. The integration into WordPress worked flawlessly for me.The system as such, which offers a very large scope and further integration, is also highly recommended. I spent a long time comparing which system I would work with, but none offers me such a wide range of services with such easy administration as this one

I use simplybook for two month now and I also installed the wordpress plugin for our website. During that time, it happend 3 times, that I got – for whatever reason – logged out of the plugin. I only noticed it, because some of our customers couldn’t book any more on our website. The last time, I had also problems to login again, because the confirmation code didn’t arrive via email. The simplybook support tends to claim that there is a problem on my side which isn’t the case. In the end, I don’t use this plugin any more, because I want to avoid bad surprises, when customers can’t book any more. For a premium account I would expect a more reliable solution and a better support from the provider.

Use it at my photo booking website for a few years, works great!

Integrating our booking system with the website was something we were dreading, but using the plugin was so easy, and very simple to setup. Already we have found our sales increasing due to our customers being able to book for themselves!
