Post 6 is a bit confusing. Does the OP need to know exactly what gear he/she is in while climbing a hill? Or does the OP just need to know that he/she has enough gearing to get up said hill. If it's the latter, a gear calculator should answer that question.
OP could use a clicking hand counter like the bouncers at the door of a night club.
