After a lot of hard work, Addicta-Ball finally has a fully functional pay to remove ads feature! This will be made available in version 2.0 where the new UI will also be released. It will cost you £0.69 (about $0.9) to purchase adfree mode.
The released date is to be decided, however I can estimate that it will be released by Thursdsy, possibly even Wednesday.
Keep checking to stay up to date!
