ProPaving measures parking lots, drives, and paved areas from satellite imagery, so you can bid a job without a measuring wheel. Measure - Tap around the pavement to measure its area. Edge lengths and the total update as you tap. - Drag corners to adjust them. A magnifier shows exactly where the corner lands. - Cut out islands, planters, and buildings. - Measure striping and curb with lines, and count stalls, ADA spaces, and other items. - Check any distance with the ruler. Auto-measure - Tap a lot once and Auto-measure outlines the pavement for you. Review it, adjust it, and keep it. - Auto-count finds the stalls in an area and adds them to your counts. Clear imagery - Switch between Mapbox and Esri satellite imagery. - Look at earlier captures of the same lot, each with its capture date, when trees, cars, or new work hide the pavement. Send - Add your customer and send the proposal by email or as a link, or preview the PDF first. - See when the customer accepts. Built for the field - Works offline. Everything saves on your phone and syncs when you have signal. - Undo and redo every change. - Your projects stay in sync with ProPaving on the web. A ProPaving account is required. You can create one in the app.

Verdict

The call

The clearest difference is in-app purchases: ProPaving at none against Cat® SIS2GO's 27. ProPaving also leads on update cadence (fortnightly vs every 6 weeks). Cat® SIS2GO's advantage is ratings volume (94 vs 3) and review sentiment (11% vs 0%). On price, rating, ads and device support there is nothing between them.

ReceptionRating · Positive reviews · Number of ratings

ProPaving holds the better App Store score, 2.3 against 2.2. That said, the two scores are not equally well evidenced: Cat® SIS2GO has 94 ratings behind it against 3, so its average is the more settled of the two. Written reviews complicate that: 11% of Cat® SIS2GO's written reviews are positive against 0% of ProPaving's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Cat® SIS2GO ships an update every 6 weeks, ProPaving fortnightly. The most recent releases landed on October 25, 2026 and October 23, 2026 respectively.
