I know I posted somewhere else on the forum a while back, but thought I'd post an update here as to my progress to-date with apps developed with B4A. So, I have Yahtzee! Free, Yahtzee! Paid (99c), Yahtzee! Plus Free, Yahtzee! Plus Paid (99c) & BallBuster!
Yahtzee! Free is by far the best performer with almost 60,000 downloads since August 2013 - of which almost 34,000 are still installed (so over 50% retention rate). I am still seeing daily net increases of 500-700 installs, with it going to over 1,000 per day for a few days over Christmas (in fact on Christmas day, it was downloaded 1,992 times! - I guess a lot of people got Android devices from Santa...). This app is being played about 45,000 times per day & generating an average of about $30 per day in advertising revenue. Yahtzee! Paid has sold a little over 500 copies, while Yahtzee! Plus Free & Paid have around 3,500 & 60 installs respectively. BallBuster has been a bit slow to take off & has been downloaded about 1,200 times in a couple of months, with a retention rate of only about 30% - but it's a bit of a silly app.
So overall I'm pretty happy that an app I originally wrote about 15 years ago for Windows is now played by 30,000+ people & is making me close to $1,000 per month - although I must say that I have put considerable time into developing it & increasing functionality & playability since its initial release.
