Ruler is an iPhone app that utilizes augmented reality technology (AR) to accurately measure the area and length of real-world objects using your smartphone's camera. Developed by MD KHAIRUL ISLAM, this app has been constantly improved since the release of AR Kit, ensuring the highest precision in measurements.

With Ruler, you can enjoy premium services such as unlimited length and area measurements, as well as an ad-free experience. Subscription options are available, and the payments will be charged to your iTunes account upon confirmation of purchase. The subscription automatically renews for the same price and duration period, unless auto-renew is turned off at least 24 hours before the end of the current period.

Ruler offers two standard subscription options: a one-week auto-renewal subscription with a 3-day trial period, and a one-month auto-renewal subscription with a 3-day trial period. To learn more about the app's privacy policy and terms of use, please visit the provided links.
