Is there extra floating button mapping like this?

Keymapper has a Floating Button for telephones, however I haven't seen somebody utilizing it. And I want there’s some mapping apps which have this characteristic, is there any app that has this floating button? Let me know! :)) (Im not taking in regards to the ones that appears like Mantis, trigger you’ll be able to't faucet it on display screen, like a nintendo or xbox, no not speaking about that.)
