About this directory

UtilCube is run as a small set of independent tools rather than a single monolith. That keeps each app fast and focused: loan and FD/RD calculators on their own apps, percentage tools on theirs, Tamil utilities on Tamil apps, and so on. This page is the directory you land on when you visit https://www.utilcube.com.
