Ola has increased referral credit to $20.
Not a bad time to sign up.
Tried it for the first time yesterday with free credit was fine.
On other threads people have mentioned drivers can be a bit late and are ones who were not accepted by Uber.
If you don't have a referral use the links in the wiki.
Also, Ola have airport discounts:

They are just like uber - most ola drivers are also uber drivers actually.
All of them would rather take ola customers (instead of uber) as ola takes a much smaller cut from the fare
