Ratios app for iPhone and iPad

This easy-to-use application compares ratios and solves for proportional unknowns. For example, is $25 for a package of three light bulbs a better value than $39 for five? Ratios makes comparisons like this easy.
It also solves for unknowns. For example, if a dog needs 2 tablets per 15 pounds and weighs 53 pounds, how many tablets are needed?
From comparing special offers to scaling recipes, budgets, or material lists, this app allows ratio problems to be solved as they appear. It is a simple application that can quickly pay for itself while making ratios user-friendly.
