Android Apps for Exercise

Hi There
Sorry to be a pain, but as i mentioned in my previous post i am starting "The New Me" on the 1st January..
Now, due to chemotherapy affecting my balance and also having Peripheral Neuropathy too i am limited to the exercise i can do..

Would anyone happen to know if there is a android app that may help me exercise wise? things i could do at home maybe? then if i fall i won't feel silly..
looked at VIRTUAGYM FITNESS but unsure so any help on apps really appreciated xxx. :blushing:
