WHAT ABOUT THE IMMEDIATE FUTURE?

I’ve been a user of DietController for many years, back when it was still a multiplatform, Java-based app. I’ve liked this app for its rather easy-to-grasp interface and the ease with which one could add or modify existing products, in my case in order to adapt the database to European products (the entire included database is based on American products, so very little use here).
Now, I’ve noticed a very annoying problem: either the product is dead and development has stopped, or there is something dramatic in the pipes. Either way, my last two requests for support have been completely ignored by Margaret Dangerfield. To the point that I didn’t even receive an acknowlegement for my messages, contrary to what is stated at the website. Also the latest update here dates back from the beginning of 2013, so 2 whole years without an update…
Okey, things happen and well, a dead product is a dead product. Yet, somebody’s still taking the money, so there is someone at the other end of this pipe.
My real question though is: how future-proof is this soft at this point? I can testify that it works on the current public beta (ß6) of El Capitan, but it’s difficult to say if it will in the Golden Master, or in the next update.
As a result, my advice is: stand clear of a product that might not work in a couple of months.
