# Poly Bridge 3 vs Build Bridge

The clearest difference is rating: Build Bridge at 4.5 against Poly Bridge 3's 3.9. Build Bridge also leads on iOS requirement (13.0 vs 16.0). Poly Bridge 3's advantage is ads (none vs shown) and review sentiment (65% vs 50%). On price, update cadence, in-app purchases and monetization model there is nothing between them.

Both are free to download. Poly Bridge 3 sells 1 one-off in-app purchase and Build Bridge sells 5 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

Build Bridge holds the better App Store score, 4.5 against 3.9. Both are backed by a comparable volume of ratings — 135 and 40 respectively. Written reviews complicate that: 65% of Poly Bridge 3's written reviews are positive against 50% of Build Bridge's, so the app with the better star average is not the one people write more warmly about.

Poly Bridge 3 ships an update every 4 days, Build Bridge weekly. Both last shipped on October 27, 2026.
