# Air Raid Siren vs LETS CROSSING

The clearest difference is review sentiment: LETS CROSSING at 100% against Air Raid Siren's 66%. LETS CROSSING also leads on update cadence (every 3 weeks vs every 6 months) and iOS requirement (15.0 vs 17.6). Air Raid Siren's advantage is ratings volume (811 vs 26) and rating (4.5 vs 4.2). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. Air Raid Siren sells 1 one-off in-app purchase and LETS CROSSING sells 5 in-app purchases, starting at $3.49 per month. Whichever you choose, the download price is not the number that matters.

Air Raid Siren holds the better App Store score, 4.5 against 4.2. That said, the two scores are not equally well evidenced: Air Raid Siren has 811 ratings behind it against 26, so its average is the more settled of the two. Written reviews complicate that: 66% of Air Raid Siren's written reviews are positive against 100% of LETS CROSSING's, so the app with the better star average is not the one people write more warmly about.

Air Raid Siren ships an update every 6 months, LETS CROSSING every 3 weeks. Both last shipped on October 24, 2026.
