Sorry to hear you’re leaving but I don’t think it’s a fair picture you’re painting, in the past two years we have shipped much more than just “colors”, we added many more options to how your note appear (checklists, tags, fonts), added the options to add tables to your notes, added the open quickly feature, added the more tag features and the tag editor, a powerful autocompletion feature, the recent projects filtering, the color options and are about to add collaboration options in a release before the end of the month. And that is not taking into account the literally hundreds of smaller features and improvements, I’d say that if you scroll down through that list that you got pretty good value for paying once £33.
Most important however, while of course you can argue that you’re purely paying for features, we would say that if you like Agenda and if it forms a critical piece of your workflow, you’re paying for making sure we can keep working on the app and keep the lights on so you can continue to use it and rely on it.
It sounds however like Agenda wasn’t perhaps a good fit for you, and that’s fine. Best of luck and thank you for the feedback!
