“Deed Calls - Area - Perimeter” is a handy universal app for iPAD, iPhone and iPod touch that lets you easily convert real property description into a boundary map. This app will let you specify the starting point, units of measure and label attributes, then draw the property boundary as you enter the angles and distances. It will display the angles and distances as well as the closure error, total area and perimeter. You may email the deed calls file (*.dcf), or output the deed calls and drawing as a PDF file. If your device has GPS capability, you may pick the GPS location as the point of beginning. Please note: Location data depends on the GPS receiver used. Continued use of GPS running in the background can dramatically decrease battery life. The Deed Calls app will let you easily toggle the built-in GPS on or off. This app comes with a built-in help file.

ReceptionRating · Positive reviews · Number of ratings

Trimble Unity holds the better App Store score, 3.5 against 1.0. That said, the two scores are not equally well evidenced: Trimble Unity has 8 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 100% of Deed Calls's written reviews are positive against 0% of Trimble Unity's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Deed Calls ships an update every 7 months, Trimble Unity monthly. The most recent releases landed on September 16, 2026 and September 20, 2026 respectively.
