# 极光预测 vs Aurora Compass

The clearest difference is review sentiment: Aurora Compass at 83% against 极光预测's 25%. Aurora Compass also leads on update cadence (every 5 weeks vs every 3 months) and ratings volume (9 vs 1). 极光预测's advantage is in-app purchases (none vs 8) and rating (5.0 vs 4.8). On price, ads, device support and iOS requirement there is nothing between them.

Both are free to download. Aurora Compass sells 8 one-off in-app purchases. 极光预测 asks for nothing beyond the download.

极光预测 holds the better App Store score, 5.0 against 4.8. That said, the two scores are not equally well evidenced: Aurora Compass has 9 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 25% of 极光预测's written reviews are positive against 83% of Aurora Compass's, so the app with the better star average is not the one people write more warmly about.

极光预测 ships an update every 3 months, Aurora Compass every 5 weeks. The most recent releases landed on October 8, 2026 and October 15, 2026 respectively.
