Calendar.online / Kalender.digital – Plugin

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 · 100% 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.

   Lange habe ich für einen Verein nach einem einfachen Kalender gesucht, der auch für Personen geeignet ist, die nur gelegentlich PC oder mobile Systeme verwenden. Das Plugin hat mich dabei umgehauen! Die Berechtigung für Leser, Bearbeiter und Administatoren sind über Links vergeben. Es ist nicht einmal erforderlich, sich über WordPress anzumelden. Die Termineingabe als Bearbeiter ist so intuitiv, wie man sich das wünscht. Einfach den Kalender aufrufen, Datum auswählen, Termin eingeben, fertig! Obwohl die Termineingabe so simpel ist, sind Exporte für die unterschiedlichsten Zwecke möglich. Richtig genial finde ich z.B. die Weiterleitung eines Termins als E-Mail! Echt ein Hammer. Die Einbettung in WordPress hat fehlerfrei funktioniert. Der Kalender verhält sich responisive und passt automatisch sein Aussehen an. Fazit: Funktional, delegierbar, stabil und einfaches Handling. 100 Punkte! Für Vereine, Teams, Musik-Bands, usw. ist das PLugIn optimal. Ich habe mich sehr gefreut das Plugin gefunden zu haben und es nutzen zu können. Hut ab!

   I think this is really a fantastic calendar for people that want to allow shared access without the nightmare of different logins and user profiles. It’s great if you have a sports team you’re coaching, want to manage kids events, social clubs, or just about anything else. Very simple to use and full of features. I really like that it offers an ics download for integration into other calendars, such as google. Top notch product and no complaints.

   DAs Plugin lässt sich weder vom Stil anpassen noch ist es als Widget nutzbar. Besonders das Design ist abschreckend, da groß und kindlich bunt. Leider für meine Zwecke nicht ansatzweise denk- oder nutzbar.
