I made many apps that automates bet placements, poker, sports betting, betfair, casino, and many other automations systems.
The app will use ocr, pattern recognition and some other techniques. the website has to be in the foreground for the app to work correctly.
The app will place the bet with a unit amount, IF it loses, it doubles the amoiunt on the next bet, IF it wins, it will start over and place a one unit bet, and so on.
The app will be completely unattended, you just set some parameters and let it run.
You can have some alarms when certain situations happen ex: reach certain PL, stop working for any reason, it can emit some sounds, or even send you an SMS if you want so.
Everything will be parametrizes.
Im confident that I can come up with a perfect solution that suits your exact needs.
Hope to work for you soon.
