For me, I actually spotted it off a reddit post, that quickly disappeared.(deleted by mods I believe), but I've been spreading it around my circle of friends since its reallly useful! I'm curious, how did everyone else come across this?
In past I used RepetiTouch pro and I wasn't happy with that, To faulty for my claims. It's a nice app( easy record and play) but I needed much more control. I tried out many other apps. One day I found Ankulua in Google play store. I had no lua skills, but with little help from other members here and much help from the Ankulua developer I wrote today my first own script and I will go on. It works very well for me. All in one - Ankulua is exactly what I need, perfect app... Respect to the developer!
