Cintanotes downloaded and installed without issue (Windows 10), and the Registration process worked fine (following the instructions from sharewareonsale).
The program itself seems to be under ongoing development, although perhaps slowly based upon comments on the User Forum, and a new version – 4 – is on the way (and, indeed, should have been released by now, per entries on the forum). Although it is not my first choice, am glad to see CN on the market.
As with any “PIM,” the user interface is a matter of personal preference, and there are undoubtedly a wide range of uses to which a creative person could find for it. From a personal perspective, I found the interface off-setting and felt Cintanotes lacks key features as compared to MY PIMs of choice: RightNote Pro and EssentialPIM.
Ver 4 of CN may narrow the gap(s), of course, but it is difficult to imagine that happening in one step.
For now, EssentialPIM’s big advantage – beyond being a “full” PIM (Contacts, Calendar, Notes, Email, Tasks & a Password module) – is its ability to sync with a native Android version. The Notes module itself is suitable for shorter notes, especially those which may require Action, with the ability to convert a “Note” to a “Task” or “Appointment” (Alarms can be set for either). Notes can also be made “Sticky,” which means they appear on the Desktop. In all, EPIM is a powerful application, although it may be “overkill” for anyone who wants a “simple” Notes App.
RightNote (Pro) is in a different league than most “Notes” applications – or, indeed, any general usage competitor I am currently aware of. (Ignoring true “Research” applications such as Mendeley, which are more academically focused.)
Perhaps the best distinction I can make is that EPIM and CN are good for Simple Notes, whereas RightNote (Pro) makes for an excellent Knowledge Database, with impressive organization & search capabilities. Only the lack of a Native Android version keeps it from being “perfect” (with full awareness that NO app is going to be Perfect!…), although EverNote integration helps for those who like EverNote (I gave up on it), AND RN offers a variety of EXPORT Options, including the ability to export as a Webbook. The Webbook format allows access on a Chromebook, although the the process can be time consuming given a large enough database. (Am running 6 Frequent Access RN databases, with another 6 as “archives.” RN Pro fortunately provides a Very Fast Search engine capable of returning results from multiple databases.)
