# Building Arcadia vs Critical

The clearest difference is update cadence: Critical at fortnightly against Building Arcadia's every 2 months. Critical also leads on rating (4.4 vs 4.2). On price, review sentiment, ratings volume and ads there is nothing between them.

Both are free to download. Building Arcadia sells 6 one-off in-app purchases and Critical sells 17 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

Critical holds the better App Store score, 4.4 against 4.2. Both are backed by a comparable volume of ratings — 52 and 147 respectively. Written reviews complicate that: 23% of Building Arcadia's written reviews are positive against 18% of Critical's, so the app with the better star average is not the one people write more warmly about.

Building Arcadia ships an update every 2 months, Critical fortnightly. The most recent releases landed on October 10, 2026 and October 21, 2026 respectively.
