I have been looking for a replacement for ListPro for what seems like 10 years? Can that be right??
I used it when I had a Windows phone. The Sync feature was awesome. I didn't want my lists on the cloud. I just wanted a light-weight program to keep lists of account information for website development. I liked the idea of a single file, that if I changed on one device I could easily sync with another. ListPro WAS PERFECT. Now I have an Android device.
I to a lot with http://cloudlist.quarterstaf.com/
but i find it just a little clunky, you have to have a connection to the net or you can't start it (no "offline" mode), but it's the best "not-quite-Listro" I have found. I just have this feeling I'm gonna wake up one day, and Cloudlist will be gone.
FWIW... I STILL USE ListPro on my PC. I keep my lists up to date manually. I use Cloudlist of daily stuff and things that I need when on the road, but I still use ListPro at the core. I can't think of any other piece of software I have used this many years and it has ALWAYS done EXACTLY what I needed it to do, when I needed it.
I have actually considered getting an iPhone JUST so I can use ListPro again to it's full potential the way I used to. But Alas... it's just not worth it. I'd love to find a replacement for ListPro.
