most GC apps i have seen have been awful, lokcing features behind pro mode, ads, etc and i was wondering if there is anything good out there? FOSS would be great but not nessacary, and if there is anything free out there, wonderful. i know desmos has an app but to be honest i am not a desmos fan. i am looking for something more akin to a ti-84 or similar. thanks in advance, comrades.
