# H2D DAB vs AlorAir

The clearest difference is rating: H2D DAB at 1.9 against AlorAir's 1.3. H2D DAB also leads on review sentiment (25% vs 6%). AlorAir's advantage is in-app purchases (none vs 11) and update cadence (every 2 days vs every 5 weeks). On price, ads, monetization model and device support there is nothing between them.

Both are free to download. H2D DAB sells 11 one-off in-app purchases. AlorAir asks for nothing beyond the download.

H2D DAB holds the better App Store score, 1.9 against 1.3. That said, the two scores are not equally well evidenced: AlorAir has 76 ratings behind it against 10, so its average is the more settled of the two.
