# Altitude Compass vs Blackout Mode

The clearest difference is rating: Altitude Compass at 5.0 against Blackout Mode's 4.6. Altitude Compass also leads on device support (3 vs 1) and iOS requirement (15.0 vs 17.0). Blackout Mode's advantage is update cadence (daily vs every 3 days) and monetization model (free with in-app purchases vs paid). On price, review sentiment, ratings volume and ads there is nothing between them.

Both are free to download. Altitude Compass sells 2 one-off in-app purchases and Blackout Mode sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

Altitude Compass holds the better App Store score, 5.0 against 4.6. Both are backed by a comparable volume of ratings — 17 and 8 respectively. Written reviews complicate that: 95% of Altitude Compass's written reviews are positive against 100% of Blackout Mode's, so the app with the better star average is not the one people write more warmly about.

Altitude Compass ships an update every 3 days, Blackout Mode daily. The most recent releases landed on October 24, 2026 and October 23, 2026 respectively.
