Contact us

We read everything. Write to us if a number looks wrong, if a calculator is confusing on your phone, or if there is a tool you keep wishing existed.

When reporting a calculation issue, include the tool name and the exact values you entered — that makes it much faster to reproduce and fix.

Response time

KaroDesk is run by a small team, so expect a reply within two to three working days. Bug reports affecting a calculation are treated as urgent.
