there is some (different!) game with an allods online theme for apple i think
there is a video about it

normal game is too resource intense for mobile phones i guess (lave alone control problems and so on)
how does it come your PC is too old? i became curious now
for playing, i often use a over 12 yo pc with windows xp (32 bit) and game runs more than fine there
it has a decent CPU @3 GHz, thats what counts for allods online, not the GPU!
