Moving to Coimbatore

Like the title states, I'm moving to coimbatore in a couple of months for work and as a female, I wanted to know what are the reliable transportation apps. P.s. I can comfortably converse in tamil and I heavily rely on autos and cabs for moving around. Also, I really don't want to bargain with drivers. Please also let me know if UPI payments are predominantly acceptable or should I always carry cash around? Just wanted to be sure.
