Questions: VESC Android APP And ADC Throttle

Hi Everyone!

i have some questions, i hope that is the correct place to ask

i'm building a ebike, and i'm using an ADC throttle to say to VESC to accelerate, this is only one way throttle, and i want to configure to accelerate and brake, so....

there is a way to config the throttle to the first half of the throttle be to accelerate and the other halt to brake?

the other question is about the VESC App in Android, i tried to install on my cellphone with the apk that i downloaded in this site, but it won't install :C i see on the google play the same at arround 1.5 dollars but i'm afraid that it won't work, i have android 10 and a NRF51_vesc ble-uart, this version will it work??

Thank you for any answers!
