Ninox vs FMP

I am considering moving away from FileMaker Pro so I am looking for another Database solution for Mac.  I have written a few databases for my business but I am not a high end user. I have no need to share the Dbs but it could be handy to do so.  I could do with using some Dbs on mobile devices but its not essential.  I do need to manage clients, make age and duration calculations, produce pedigrees, sales documentation, keep health and weight records as well as track communications (email, calls etc).  I am looking for some advice on whether Ninox would be a better choice than FMP which is increasing expensive and doesn't seem to have moved forward (except in price) in the last 6 years.  I am sure Ninox can do all I have asked for but how easy would it be? - a lot the above is painfully difficult on FMP so, for example,  I use Numbers for tracking weight gain by day and so forth.  Ideally a good selection of ready to use scripts would be a big help so that I could, for example, display a period of lapsed time as days and months without having to write (or blag) a lengthy script myself.
