# 觀天氣 vs 環境即時通

The clearest difference is rating: 觀天氣 at 4.5 against 環境即時通's 3.6. 觀天氣 also leads on review sentiment (77% vs 50%) and ratings volume (64 vs 7). 環境即時通's advantage is ads (none vs shown). On price, update cadence, in-app purchases and device support there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.

觀天氣 holds the better App Store score, 4.5 against 3.6. That said, the two scores are not equally well evidenced: 觀天氣 has 64 ratings behind it against 7, so its average is the more settled of the two.
