It doesn't work at all, there's no settings, I'm using it on a mobile device, galaxy note 9, it has no setting , I was expecting suggestions or optimal line ups, which is why I paid for it. It only puts out what I put in, so if your looking for advice it's no help, it didn't optimize, $40 down the drain. I was trying to get roto grinders and ended up with this so called line up optimizer. I'm not seeing it, very disappointed, save your money, just take your $40 and play it on draft kings .

Hi Michael, thanks for reaching out. It sounds like you are manually entering players instead of using the optimize button. You can pick and choose manually, optimize an entire lineup, or do a mix of both. Our customer support team would be happy to help walk you through the features, support@rotogrinders.com

If you try to use the rotogrinders website, there is a pop-up message that says something to the effect, 'Use the app, it's better (really!). I can confidently say, "It's not. Really".

Terrible app for mobile device. No setting button in actual app. Must go on computer to use this app to it full potential. There lack of information when building line ups on the mobile app. This is not an easy application to navigate through. And a poor job explaining on how to correct line up and over stacks players in game and prevents line up to be created. I would not recommend this app if I could give negative stars I would. Poor design application and not easy to navigate through
