Easiest/fastest ELO changing?

Sort:
invented

Howdy folks-

Best way i've found to improve my game [besides studying, which i'm too lazy for!] is to simply play and replay combinations.  And that's far easier, and more informative, if you can get that the ******* app to play stronger, easily.  [Yes, playing at ELO 1400 you won that exchange, but at 1500...?]

The only! app i've ever found that does this even semi-easily is Bringer [a humble orpaned freeware].  Fritz 5.32 is a bit slower.

Anyway, my question is: have i missed any free or paid apps that allow FAST [hotkey'ed, please please please] ELO changes?

thanks for your time...
