So, it's best to just use it with one casino for the best usage of it. Since there are not a lot of casinos that shares their API.
That only means that only a selected few that has and allows it that any tool if there is any to maximize its use as what OP is looking for.
Yes, it's a great tool actually, since you can see your statistics (charts), pnl, days or time which you are "lucky" or win or losses, your winrate on such game, game provider, or overall win rates. It is really helpful for analytics and will give you hint for your next steps. And just like this, as its very helpful to users, you cant see such feature on any casino, why? Because it will give hints to their users, that's it give you an idea that casinos are there for business only, for their profits, yeah?
Yeah, exactly. They're there mostly just for the business and they are not a foundation or a charity that will just give profits to the gamblers.
In this case, those gamblers that sees it will have an idea whether they should gamble for more or they should have stopped already long time ago.
.Is it in tracking expenses or it's tracking time management.
It only becomes an expense if there is some payment for such tools. But if there is none, it's a good way for additional or better overall management of your gambling activity.
