# Haze@SG vs Aurora Watch Global

The clearest difference is ads: Aurora Watch Global at none against Haze@SG's shown. Aurora Watch Global also leads on monetization model (free vs free with in-app purchases). Haze@SG's advantage is update cadence (every 9 days vs every 6 weeks) and ratings volume (11 vs 1). On price, rating, in-app purchases and device support there is nothing between them.

Both are free to download. Haze@SG sells 2 in-app purchases, starting at $0.99 per month and Aurora Watch Global sells 3 in-app purchases, starting at $2.99 per 7 days. Whichever you choose, the download price is not the number that matters.
