User reviews

Basic calculations are wrong

Calculations as simple as finding the area of a 4 sided object are false. Wouldn’t trust this if it were the only calculator available.

Response from developer

Thank you for sharing your feedback. The area calculation for four-sided shapes follows standard formulas and works correctly when inputs and units are selected appropriately. In some cases, confusion can occur due to unit selection or input method. We request you to please check the latest version and verify the inputs and units used. If you still face any issue, kindly contact our support team with details so we can review it further. We’re always happy to help clarify and assist.
