Please drop apps recommendations for planning the whole year

So, I'm planning to actually have a productive year for once, but I literally can't do anything without a list with EVERY TINIEST detail planned or I will forget most of the stuff. I'm searching for an apps that will let me plan the whole year and stuff like tests, budgets, birthdays, routine, etc (at least one of those things🙏). Also I don't have an iphone and it would be nice if the app was free/not everything was for premium users
